Apple Watch Could Be a Password Alternative

With password tolerance levels at an all time low, alternatives to the pesky and insecure authenticators are beginning to abound. One of those alternatives could be the Apple Watch.

Even before Apple's latest gadget began shipping last week, MicroStrategy announced it was extending its Usher enterprise security solution to the Apple Watch.

Usher, launched earlier this year, lets an enterprise use smartphones to authenticate its users and eschew user names, passwords and tokens. The solution has two parts: a back end that runs in the cloud, and an app that runs on mobile phones.

Usher on the Apple Watch allows it to act as a digital key that employees can use to log in to business systems, unlock devices, validate an identity and open entryways.

The Usher app uses all of the Apple Watch's repertoire -- glances, notifications and force touch -- to perform its functions. It is designed to detect a variety of business systems through a wireless connection as users approach.

For example, as a user walks up to a workstation, a notification will appear on the watch to unlock the hardware, which can be done with a tap of the timepiece.

Security Plus Convenience

With Usher, an enterprise can remove the need for user names, passwords, physical IDs and badges, and replace them with a software key that can reside on a smartphone or the Apple Watch.

"That can be a transformational and important application for the enterprise, because it rids it of one of the real weaknesses in enterprise security," said Paul Zolfaghari, president of MicroStrategy.

"What the watch does is give Usher one more level of convenience," he told TechNewsWorld.

Actually, the watch may be better suited for authentication than a phone.

"The watch is designed for short interactions," Zolfaghari explained. "A short but important interaction is the transaction that takes place when somebody is being granted authorization to do something."

The watch has another benefit for the overseers of enterprise security.

"If you think about enterprise security and security in general, what you find is that for something to be more secure, it has to be less convenient," Zolfaghari said.

"It's the opposite with the Apple Watch," he continued. "You get greater security with a higher level of convenience."

Bad Password Hygiene

As if any more evidence were needed about the insecurity of passwords, LogRhythm released the latest in a long line of surveys finding that users continue to ignore good password hygiene -- except in maybe one instance.

Only 19 percent of users created unique passwords for all their accounts, according to the survey of 520 full-time employees at organizations with 250 or more employees in a number of industries.

However, when it came to their personal banking accounts, 78 percent of the respondents said they used a unique password there.

Despite the apparent concern users have over their personal finances, there seems to be little change in their general attitude toward password hygiene.

"Weak and stolen credentials is still one of the most common threat vectors used by the bad guys," said Mike Reagan, chief marketing officer at LogRhythm.

In addition to finding 81 percent of participants reused passwords in one way or another, the survey found that 79 percent of the respondents changed their passwords less frequently than once per month.

"The reality is that credentials are going to be stolen. The question is, what is the value of a credential to a bad actor?" Reagan said.

"The value of a stolen password drops precipitously when a person frequently changes passwords," he continued. "If I'm changing my password every 15 days, I'm really limiting the value of my stolen credentials."

Zombie Apps

Appthority waved a red flag last week over a what it sees as a growing problem in the mobilesphere: zombie apps.

Zombie apps are created when a program is removed from an app store but remains on a person's device. Apps can be removed for any number of reasons -- a developer pulls it because he doesn't want to support it anymore, or the operators of the store toss it for violating their terms and conditions.

"When it's removed from an app store and not from the devices, it's the equivalent of announcing a product recall and not recalling the product," said Domingo Guerra, president and cofounder of Appthority.

"It's like saying, 'We can't sell this car anymore because it's not safe,' but not telling the people who are driving the car," he told TechNewsWorld.

Because zombie apps are no longer supported by a developer, any flaws found in them by bad actors can be exploited without fear of being corrected. That can make them dangerous to a user -- even more so than mobile malware.

"We looked at over 500,000 apps on enterprise devices," Guerra said.

"Less than half a percent contained malware. More than 5 percent of iOS devices, and almost 4 percent of Android devices were dead apps," he noted.

"We also found that every single enterprise has dead apps," added Guerra. "That's not true of malware."

There would be a major corporate data breach this year that leverages a mobile device, Guerra predicted.

"We're starting to see mobile devices replacing laptops and desktops in the enterprise. The [attack] surface vector is increasing tremendously because of that," he explained. "We also seeing more and more work being done on mobile devices, so the value of the data on them is increasing."

Canon EF 100mm f/2.8 USM Macro Review

The Canon EF 100mm f/2.8 USM Macro is one of two new 100mm macro lenses in Canon's range, the other being the more expensive L-series optic, the CanonEF 100mm f/2.8L Macro IS USM, which has the advantage of a new Hybrid IS system.

This one may lack image stabilisation but, nevertheless, it's priced attractively and competitively specified.

It contains an internal focusing system, which has the dual advantages of maintaining the same working distance throughout its focusing range and keeping the front element static as this happens.

Focusing itself is carried out via a ring Ultrasonic Motor (USM), which Canon claims offers fast and quiet autofocus, while the further inclusion of a three-group floating system is said to ensure correction for aberrations throughout the lens's focusing range.

On the inside, Canon has incorporated a secondary diaphragm to block stray light when shooting at f/2.8, while a single Ultra Low Dispersion element is also included to help minimise chromatic aberrations.

To help improve light transmission and to reduce both flare and ghosting, Canon has treated the elements within the lens with its Super Spectra Coatings. This works by cancelling out the reflections from the surfaces of the elements, so that more light can pass through to the sensor and not bounce around inside to degrade image quality.

The lens incorporates a particularly broad rubber manual focusing ring on its barrel, which turns easily and makes clear when the ends of its focusing scale have been reached. It can also be used to override the autofocus system once focus has been confirmed.

This is joined by two switches next to the distance window - one that alternates between manual and autofocus and another that closes off the focusing range to 0.48m-infinity for non-macro photography.

The distance window, meanwhile, indicates the focusing distance in both feet and metres, and also shows the current reproduction ratio down the maximum 1:1.

The mottled finish of the Canon EF 100mm f/2.8 USM Macro's body is similar to that of some previous Canon EOS DSLR cameras, such as the EOS 600D and EOS 5D Mk II, although its design is a little dated when compared with more recent finish options from other manufacturers.

The mount is constructed from a solid metal for durability, and above it sits a large red lens mount index that indicates the mounting position clearly.

The only other external features of note are the 58mm filter thread at the opposite end of the lens and the grooves around it, which can be used to mount either an external lens hood or a macro ring lite flash.

At this price we don't necessarily expect an image stabilisation system, and for macro work a sturdy tripod is generally recommended as a better idea. However, since Canon lenses don't offer image stabilisation inside their bodies, this puts it at a slight disadvantage to similar lens/body combinations from other manufacturers when used for non-macro work.

This is particularly the case with APS-C bodies such as the Canon EOS 600D and EOS 7D, where its effective focal length rises closer to 160mm, and this omission also means that the viewfinder image isn't stabilised for more precise composition.


Thanks to the use of a piezoelectric motor, focusing noise is about as silent as expected as the lens travels between its two extremes, and it's able to quickly shift its focus between varying distances before promptly confirming focus.

Furthermore, the use of different text colours in the distance window makes it easy to differentiate between its three readings, while the size of the focusing ring means that it's easily adjusted with just a finger if required.

Its positioning towards the front of the barrel makes this manoeuvre a little more difficult for those with smaller hands, but in most situations the macro lens will no doubt be either left to autofocus or be manually adjusted more precisely on a tripod.

Control over distortion is good, and the absence of chromatic aberration in the centre of the frame is particularly impressive, although as you venture further away from the centre it's clear that there's room for improvement.

Although central sharpness at f/2.8 is impressive this slowly drops off to softness towards the edges. By f/8, however, all is forgiven as the Canon EF 100mm f/2.8 USM Macro records excellent sharpness right across the frame. Predictably, things aren't quite as good at its smallest apertures, although even here consistency is still reasonable.


Overall then, this lens is a capable performer, with quick and silent autofocus system and generally good to excellent image quality. While more expensive then the Tamron SP AF 90mm F/2.8 Di Macro 1:1, it has the distinct advantages of an internal focusing system and a much quieter motor.

HDR :Better results from multiple exposures

The sensor in a modern digital camera has less dynamic range than the human eye. That's why we're often disappointed with photographs we take: we don't see the sky as washed out, or the shadows as dark as they appear in our photos.

Naturally, there are now ways to circumvent this using the power of the PC: enter the high dynamic range image processing algorithms.

When we purchase a digital camera, we're often concerned with the resolution of the sensor (the number of megapixels), whether it produces images in JPG or RAW format, and whether we can use different lenses to get images from close up or far away. We're not generally concerned with the dynamic range of the sensor in the camera – in other words, the range of light levels that the sensor can capture.

It turns out that old-style film has less dynamic range than a CCD (charge-coupled device) – the sensor that registers light information that's built into modern digital cameras. If you like, we've moved forward in terms of dynamic range and also, incidentally, in terms of noise: film is noisier at low light intensities than digital.

EYE VS SENSOR: How the eye perceives light intensity (blue line) compared to the way the camera does (red line)

Both types of camera perceive a narrower range of light levels than the human eye. That's why when we take a photograph of a landscape, for example, we get an image that doesn't register the cloud formations in the sky (the sky becomes washed out) and the shadows become undifferentiated black.

If you're anything like me, you tend to get a little frustrated and disappointed that the camera isn't recording what you're seeing exactly, but I dare say we've all become rather used to the problem.

What is HDR?
There is, however, a way around this called HDR image processing (high dynamic range). This is a set of algorithms that process images to increase their dynamic range.

With HDR, it's possible to produce an image that has a much greater range of light levels to approximate what the human eye can see, or even to make fantasy images that look nothing like real life.

However, I'll also note that you will run into some issues. For example, the monitors we use to view images also have a smaller dynamic range than the human eye.

Back in the days of film cameras, it was possible to increase the dynamic range of a photo when you printed the image after developing the film. Photographers like Ansel Adams were experts at using this kind of image manipulation – known as dodging and burning – to produce the dramatic photos we've all seen and perhaps bought as posters.

Dodging decreases the exposure of the print making the area lighter in tone, whereas burning increases it making the area darker in tone. Recall that in film photography, the film is a negative version of the photo. Dark areas on the negative will show up as lighter areas on the print paper because the light-sensitive silver salts in the paper will be less exposed, and therefore appear lighter once the print is fixed. Light areas will show up darker on the print, because more light hits the silver salts.

To apply dodging to the print, the photographer would cut out a shape from some opaque material like card to block off part of the scene, and then expose the print paper with that card between the projector and the paper. Because less light hit that part of the scene, it would appear lighter.

Burning was done in a similar way, but this time the photographer wanted to expose part of the scene longer than the rest. They would cut out a shape that would block off the rest of the scene, letting the part to be brightened receive more light.

There are other techniques and materials that can be used, but as you can imagine, dodging and burning this way was a labour-intensive process and was usually only done for art photos and the like.

Another issue is that dodging and burning are physical manipulations that happen in real time, and it's hard to replicate the same effects across a set of prints so that the resulting images are all the same. With digital photographs and programmatic image manipulation, it's a lot easier to create images with a higher dynamic range.

The process goes like this. First you take at least three photographs of a scene. Ideally, these photos are taken with your camera on a tripod so that they all register exactly the same scene. I've tried using a hand-held camera and it just doesn't work as well during the HDR processing – there's always some obvious scene shake that can be seen.

Similarly, the scene itself should be as static as possible: any moving parts (like leaves fluttering in the wind, waves crashing on the beach, or cars or people passing by, for example) won't be the same in each image, causing scene shake in the processed HDR file.

Although the photos are of the same scene and have the same focus and aperture settings, you take them using different exposure times. For best results, you should shoot one photo as normal, and the others two stops either side. Increasing exposure by a single stop doubles your exposure time, and decreasing by a stop halves it.

The dynamic range in photography is the number of stops between the darkest part of an image where you can still resolve detail and the lightest part. DSLRs generally have about 11 stops of dynamic range at low ISO values, and point-and-shoot cameras a stop or so less.

The external Viewsonic monitor I'm using with my MacBook Pro has almost 10 stops, which means that the photos I take with my camera already have twice the dynamic range that my screen can show.

Some cameras, especially DSLRs, have a mode whereby you can shoot three photos as a set, the other two bracketing the first in terms of exposure. The different exposures are regulated by the camera automatically.

On my Canon Rebel XTi (also known as the 400D), this is AEB mode (auto-exposure bracketing) and I can set the required +/- 2 stops there. If your camera shoots RAW instead of JPG and your HDR image processing application supports it, it's possible to just use one photo. The results won't be nearly as good though.

Once you have your three differently exposed photos, it's time to process them. The first stage is to analyse all three photographs in order to merge them as a single HDR image.

Encoding photos

NORMAL EXPOSURE: Our scene normally exposed

Without getting bogged down in compression details, image formats and so on, traditional images (like an individual photo from our set of three) encodes colour information for each pixel as a set of three bytes, one for red, one for green and one for blue. Each colour channel for each pixel can therefore represent 256 different levels, and the pixel itself can be defined as a single 24-bit value.

An HDR image is different. In a simple sense, it encodes more bits per colour channel per pixel than a standard image, but that's not the entire story. To understand why, we need to understand what's meant by 'gamma correction'.

OVER-EXPOSED: Our scene over exposed. Notice the difference in colour tones to the normal exposure

Gamma defines the difference between a pixel's colour values and how bright it is actually perceived (its luminance). For a camera, if you double the amount of light on a sensor's pixel, a value twice the original is detected – the relationship between a pixel's value and its luminance is linear.

This linear relationship doesn't apply for our eyes. When we increase luminance at low light levels, we perceive a larger increase in light. At higher light levels, we don't perceive increases in luminance as well. Our eyes are more sensitive to changes in dark tones than changes in light tones.

Accounting for this difference is known as gamma correction. A camera will apply gamma correction to an image before it saves it as a JPG file. It's the same with image processing applications that work with RAW image files, when you save an image as a JPG. In other words, instead of encoding the values of the pixels reported by the sensor, it will apply a gamma correction (the industry standard value is 1/2.2) first.

Instead of recording the real values of the pixel colours, it will encode them as colour tones that we perceive as varying uniformly. In effect, the code that saves an image as a JPG file uses more bits to encode darker colours than lighter ones.

When you view such a gamma-encoded JPG on your screen, the screen software will apply the reverse gamma correction (a gamma of 2.2 usually) so that the image you see is roughly the same as the original scene. Lighter shades will have less variation than darker shades, though.

UNDER-EXPOSED: Again, notice the differences in colour between this and the first two shots

Notice also that merging three JPGs to produce an HDR image would necessitate that the gamma correction be reversed before the merge. JPG is already a lossy compression algorithm (we're losing image information when the camera creates a JPG, smearing out high-variation regions of the image), which means that our three differently-exposed photos should all be in RAW format.

Now back to the HDR image. It converts colours as tones using the gamma correction just discussed (so darker tones have more shades) and encodes them as a floating point number, using either single precision (32-bit) or double precision (64-bit). All three standard images are used in this conversion/encoding process, since each will have a different complementary set of tone information.

There's a lot of redundant information, so the most popular HDR format compresses the RGB tone data as three fixed point values, with an extra byte holding a common exponent.

Viewing the image

TONE-MAPPED HDR: And like magic, the final result shows more dynamic colours and contrast to the original photos

So now we have an HDR image whose tones are encoded in high fidelity using a special encoding scheme. To view it, however, we have to export it as a JPG again.

Because of the +/- 2 stops bracketing, the HDR image has a dynamic range of roughly 14 stops, which happens to be about as much as the eye can perceive, but we have to convert that wide dynamic range into the 10 stops of the screens we use.

We have to map the HDR tones into the range that can be displayed on a monitor. Since we're going to be removing information (or reducing the amount of data) in order to do this, tone mapping is a lossy one-way process. It also tends to be an interpretive process, much as dodging and burning was to the film photographers, requiring a good eye and attention to detail and lots of time tweaking and experimenting.

In any HDR image-processing application, there will be several knobs or sliders you can adjust to change the tone mapping, and thereby the look and feel of the finished low dynamic range image (sometimes known as LDR).

Some examples include exposure or brightness, gamma or contrast – sharpening tools that alter the local appearance of parts of the image. Some may come with presets that generate an LDR image according to the image style you want to show (Photomatix, the application I use, has a preset called Grunge and yes, the results are pretty grungy).

There are several tone-mapping algorithms that can process an HDR image to produce an LDR version (a hands-off algorithm), but it's a field that is being actively researched and is changing rapidly.

The biggest issue that automated algorithms have to solve is that tone mapping, by its very nature, reduces contrast (contrast is a difference in luminance: the higher the contrast, the greater the difference in luminance or tone). The earliest hands-off algorithms were global algorithms that acted on the image as a whole.

An example of global tone mapping is to take the tone (or luminance) information and scale it linearly to the required range. Luminance is a value on an exponential scale (each increase of one stop doubles the brightness), so the linear scaling is usually done on the logarithm of the tone values. The problem with this was that it paid no attention to areas within the image with local high contrast.

Other algorithms attempt to take into consideration regions of the image that have wide variations in contrast. The algorithms use a range of methods to generate an LDR image as a multi-pass process. Some, for example, tone map most of the image one way, then map the localised high-variation regions using another method to maintain contrast.

As you can see, the problem of HDR image processing hasn't been completely solved yet. Nevertheless, it's fast becoming an accepted way to process images with high contrast, and can produce some stunning photographs.

BlackBerry App News: Spotify finally arrives on App World

After yesterday's apologetic bounty of free apps, RIM has some good news on the app front today, with the announcement that Spotify is finally available for the BlackBerry platform. Finally.

Spotify has finally unleashed its Premium music streaming services on the BlackBerry-toting masses, by launching its mobile app.

Spotify mobile is already available for iOS, Android, Windows Phone, Nokia and even WebOS got some love from the Swedes before the BlackBerry App World is now getting a look in.

To make use of the app, just like on all of those aforementioned platforms, you'll need a Spotify Premium subscription, which costs a tenner a month.

Once you're signed up you'll have access to millions of songs, offline playlists stored on your handset and syncing of playlists between desktop and mobile versions. There's also track scrobbling to

The app is available to download in preview from the BlackBerry App World, but a full and complete version will be released very soon, according to RIM.

The launch of Spotify comes at an ideal time for RIM, which is looking to convince current users that it is worth staying loyal to the brand following last week's disastrous internet services outage which brought BBM down across the world.

Earlier in the week, the company says it was offering £63 worth of premium apps free for its users as an apology for the whole sorry episode.

Beats Wireless headphones review Hands on

We got our hands on the Good Dr Dre's new wireless Beats headphone and they look like they're shaping up to offer great cable-free audio from the Compton lad

Whether you're listening to NWA's Straight Outta Compton or Jedward's Planet Jedward, Dr Dre's Beats by Dre headphones have become the premium brand headphones to be seen with in public. From Premier League footballers to the teenagers who hang outside our local branch of Lidl - everyone wears them. And now they're wireless. That's a great thing, right?

Well... these new cable free cans connect to any music playing device via Bluetooth, something that can cause a dip in audio quality compared to going wireless via WiFi or say Apple's AirPlay for iTunes. Nevertheless Bluetooth remains the most practical option and Dre's team are promising the quality Beats are known for has not been compromised.

Beats Wireless: Build quality

Smaller than the "classic" Beats Studio range that Beats By Dre have built their reputation upon, the Beats Wireless is essentially a tweaked pair of their smaller Solo 'phones. They're slightly weighty due to the batteries, controls, Bluetooth tech, and microphone built inside, but it's a good weight for the size of the product. It feels right in your hand, on your head, and crucially around your neck (where most people seem to wear Beats). The squishy ear pads, and smoothly folding arms add to the general feel that this is definitely a high end product.

Beats Wireless: Style

Even if you hate Dre (yes Ice Cube, we're talking to you here) you cannot deny that these new headphones look pretty damned beautiful. At a time when Beats have launched some neon coloured Studio headphones, these are gloriously black, minimalistic, with more curves than a zero. All the class of the Solo, with ear cup controls that are thankfully barely visible. The controls being as they are may make the headphones fiddly to use for some, but let's face it you're not looking at the buttons whilst they're on your ears anyway. Unless you're some kind of weird lizard or owl.

Beats Wireless: In use

The built in Bluetooth technology wirelessly connects to your smart phone, tablet, laptop, PC, whatever. It does this with absolutely no fuss - our pair connected to our iPhone and started playing music without us even asking it to. Managing the volume, skipping tracks, and answering phone calls is all managed directly from the ear cups, which could take some getting use to. For a while you might be taking the cups off to remember what button does what, but that time will pass quickly enough. Recharging via a USB is simple and fuss free, and the quality of audio meanwhile is simply excellent despite our fears over what the Bluetooth might do to it. If we're being pernickety, we'd say it's perhaps a little bassy, but there's little distortion and the sound is anything but flat.

Beats Wireless: Verdict

A UK price tag has yet to be confirmed, but they'll no doubt be in line with other Beats prices (AKA not cheap). As with all 'phones however you pay for what you get, and Beats Wireless ooze quality, crucially in the key areas of audio performance and style. Hell, even the way they fold up feels so right. If it's priced sensibly, this could be one of the must have audio products of 2012.

Beats Wireless availability: later this year for purchase exclusively at Apple stores.

Beats Wireless price: TBC (US $279)

Panasonic Lumix DMC-FZ150 review

A flagship super zoom joins the Panasonic FZ line up. So what does the FZ150 offer to justify being priced similar to an entry level DSLR?

When you’ve used a camera with a large zoom lens bolted on the front, going back to a pocket model with a weedy 5x or even 7x lens can feel like trying to take a picture with one arm cut off. Closely resembling the feature set of the FZ48 model, and styled like a miniature digital SLR, the FZ150 – updating the FZ100 – likewise fields a 24x optical zoom, starting out at a wide angle 25mm equivalent, running up to 600mm at the telephoto end, and boasting grandly named Black Box Nano Surface Coating technology to minimise lens surface reflections.

We also get, as expected, Full HD 1920x1080 pixels video clips at 25fps (even its semi-pro G series interchangeable lens models are yet to stretch to 30fps) into the bargain, and a slot-on lens shield is provided in the box to minimise sun glare in bright conditions. It’s worth pointing out that, unlike a DSLR, the FZ150’s lens cannot be swapped however. But then again, an equivalent lens on a DSLR would be both prohibitively bulky and expensive, so with the FZ150 you’re getting greater portability, if not quite as sharp image quality.

As with the FZ48 camera we recently reviewed, the new FZ150 goes up against the slightly higher-powered likes of the Fujifilm Finepix HS20, Canon PowerShot SX30 IS, Olympus SP-810UZ and Nikon Coolpix P500, to name just a few competitors in its ‘super zoom’ category. Like the best of them the Panasonic incorporates stereo microphones just behind the lens barrel and incorporated within the housing up for the pop up flash, though stills resolution is again a modest 12.1 megapixels. Its maker has obviously thought 12 is more than enough for the consumer market and crowding a small-ish sensor with more pixels will only lead to more visible grain if shooting at top ISO3200 light sensitivity setting. It’s a sensible if hardly dynamic choice.

Hitting the shops this month (October 2011), suggested retail price for the Panasonic Lumix DMC-FZ150 is £469.99, so £120 pricier than its almost carbon copy in the existing £349.99 FZ48. Let’s take a look at how its manufacturer might justify this extra expense.

Panasonic Lumix DMC-FZ150 Controls (ease of use)

Like its FZ series forebears this camera is chunky, which on the upside means a large and comfortable handgrip, with enough space between it and the lens barrel to prevent your knuckles chaffing against it. As well as a decent grip the camera benefits from optical image stabilisation to help counter-balance camera shake when shooting towards the extremities of the zoom. Feeling a little plastic-y to the touch, dimensions are 124.3x81.7x95.2mm, so the FZ150 won’t fit in a pocket. Weight is a reassuring 528g with rechargeable battery and SD card inserted, lending it that built-to-last quality.

The shutter release button that sits on top of the handgrip is large, obvious and springy, and is ergonomically encircled by a lever for operating the zoom; so in practical terms it’s easy to zoom in and fire a shot without having to take your eye off your subject. Alternatively a second, larger zoom lever is provided on the lens barrel, should you wish to zoom with your left hand and press the shutter with your right. A busy shooting mode dial contains 14 options, including intelligent Auto, which ‘recognises’ common subjects and implements the best settings for you, allowing for pure point and shoot operation, as well as the usual smattering of pre-optimised portrait and landscape modes. This being a Panasonic we also get a Creative Control setting, which allows the picture to be tweaked in camera. Choose the ‘Expressive’ option within this setting to boost the intensity of colour for example, which can work really well.

In summary there is the option here to use the FZ150 as a glorified snapshot, albeit one with a huge lens and so wide array of framing options, or get more ‘hands on’ and customise its features as you desire.

Panasonic Lumix DMC-FZ150 Screen

The FZ150 differs from the FZ48 in that, happily, it features an angle adjustable 3-inch LCD screen, which can be flipped out parallel to the body as you would with a palm camcorder. Furthermore the screen can be flipped or twisted so that the 460k-dot resolution LCD is facing the body for added protection when inactive. While this is a boon for composition and certainly worth having for low and high angle photography, it’s a moot point as to whether it’s worth £100+ more than the fixed screen on the FZ48 alone.

Directly above the LCD is a smaller, lower resolution 201.6k dot electronic viewfinder (EVF) that juts out, but not far enough that your nose doesn’t squash up against the screen below when you bring an eye level with it. Although useful on models with a fixed LCD, we felt the larger angle adjustable screen here made the EVF slightly superfluous. A button is provided for switching between use of the EVF and LCD: an eye sensor for doing this automatically would have been even better. But as we say the LCD is so flexible the EVF here is even more secondary to use of the FZ150.

Panasonic Lumix DMC-FZ150 Speed (performance, basically)

Though we’d have preferred Panasonic to have located an on/off lever surrounding the shooting mode dial, like on its GH2 model, whereby the camera might have been activated with a flick of the thumb, instead a simple power switch sits to the far right of the top plate.

A finger flick of said button and the FZ150 is ready for your first photo or video in two seconds. Should users desire, the camera is capable of up to 12 frames per second (fps) continuous stills capture, and impressively at full resolution too, up from the 3.7 fps of the FZ48. Also a boon for sports photography is 220fps high-speed video, which provides slow motion results. Even in normal single shot mode the camera is fast, locking onto target in an instant, but officially 0.1 seconds.

Otherwise the camera responds fluidly to each button press and menu selection, the lens barrel adjusting from maximum wide angle to extreme telephoto in all of four seconds if you hold a finger down on its zoom lever. Fortunately the full extent of the optical zoom can be used for video as well as stills.

Panasonic Lumix DMC-FZ150 Battery

The Panasonic Lumix DMC-FZ150 comes supplied with a chunky DMW-BMB9E rechargeable lithium ion battery, with mains charger and plug provided in the box. This is good for approximately 410 pictures from a single charge, so marginally better then the FZ48 that uses the exact same cell, according to industry testers CIPA. The ability to eek out power over roughly a week’s occasional use means that this is a good option for a jack-of-all-trades camera to take on holiday with you, should an autumn or Christmas break be planned.

Panasonic Lumix DMC-FZ150 Pictures and video

We sometimes find regular stills from Panasonic cameras to be a little flat, so the ability to occasionally add a sense of dynamism with the Creative Control modes, indicated by the artist’s palette on the shooting mode dial, is welcome. Here we enjoyed the ability to swap between retro (slight yellowish tint), high key (high contrast), pinhole (Box Brownie type shaded edges), and the now ubiquitous miniature effect, being able to see what effect they would have before we fully squeezed the shutter release. Like most digital cameras that are, at their heart, point and shoot snapshots, it’s best to stick at ISO800 or below to avoid image noise, and though we did occasionally get soft shots shooting at maximum zoom, the image stabilisation feature means that there’s a higher chance of getting usable results with it switched on than without.

As we noted earlier, the zoom can be used when shooting video, though the built-in mics do inevitably pick up the sound of the lens barrelling through its focal range, with an audible ‘clunk’ as it comes to a stop. This will be less noticeable in busier environments. Though a dedicated video record button commences shooting automatically, a manual or ‘creative’ video mode found on the top dial also lets users adjust exposure and colour for video shooting – so if you’ve wanted to shoot a black and white epic, this could be the camera for you.

Panasonic Lumix DMC-FZ150 Verdict

The FZ150 is a good option for anyone looking for the one camera that does it all. Though it is not particularly cheap or portable, you’re not going to be considering this bridge camera – so called because it forms a ‘bridge’ between the simplicity of use of a compact and the relative complexity of a digital SLR – unless a large lens takes priority over everything else anyway. If you’re not bothered about a tilting LCD screen or faster shooting speeds for action photography though, save yourself £120 and go for the FZ48.

Motorola Razr review Hands on

With a Motorola Razr UK release date pegged for early November – just weeks away - T3 has gone hands-on with the new Android Gingerbread version 2.3.5 powerhouse.

In spite of the official unveiling of Android 4.0 Ice Cream Sandwich yesterday alongside the Samsung Galaxy Nexus, Motorola has confirmed that its 7.1mm thick Android device will be powered by the older Android Gingerbread version 2.3.5 of the Google mobile OS.

However, Motorola has confirmed that the Motorola Razr will be upgraded to Android 4.0, or Ice Cream Sandwich, in the first half of 2012. The official Motorola Razr UK price is not yet known, especially network pricing, but a host of retailer pre-orders are already live.

Motorola Razr Screen.

Measuring 4.3-inches across the new Motorola Razr plays host to a Super AMOLED Plus display that is stunningly sharp, vibrant and responsive. Featuring well contrasted and beautifully bright colours, the Razr’s screen is of comparable quality to those lining up on the new Apple iPhone 4S and T3 Gadget Award winning Samsung Galaxy S II.

Although visibly slim the Razr’s minimalist form factor does not transfer to its feel within the hand with the ultra wide 4.3-inch Super AMOLED Plus display feeling large despite the device’s disconcertingly light form factor.

Motorola Razr Camera

Boasting an 8-megapixel rear-mounted camera with 1080p video recording capabilities the Razr’s snapper falls, on first impressions, slightly short of expectations. Whilst viewing the camera’s live view on the expansive and vibrant display, content appears grainy and lacking clear definition.

Once snapped, however, shots are of an acceptable standard with little blurring and a broad arrange of vivid colours. Sampled under low light conditions the Razr’s camera requires further in-depth testing before writing off its on paper possibilities can even be considered.

Motorola Razr Specs

Responsive and zippy thanks to its high-end handset required 1.2GHz dual-core processor and 1GB of RAM the heavily skinned Razr looks fantastic with the Kevlar rear panel appearing luxurious and a welcome break from the standard black plastic.

Whilst the scratch resistant, life surviving Gorilla glass screen coating and splash proof nano technology could not be tested during our hands-on review of the Motorola Razr, the display technology appears not to affect the AMOLED’s brilliant picture quality or responsiveness.
