The problem with cameras on mobile phones… (Phones)

Posted by – March 26, 2010

The problem with cameras on mobile phones is that they’re all crap – do you want to know why?.

In the olden days (you know when people used film cameras) no matter what camera you had, whether it was a cheap piece of plastic crap or the best SLR in the world, it all had one thing in common: 35mm film*. And the one thing 35mm film did well, was take photos no matter what the lighting conditions. Even in dark situations, without flash, you’d still be able to get some kind of photo from it. * assuming you weren’t using a 110 or APS camera. An example on flickr, and another example above with flash (I assume the flickr link is using 35mm film which measures 24x36mm).

Night shot Casio Z120

With a digital camera – nearly all of them have flash (I’d estimate 99%) – so in dark conditions you can use the flash and get a half decent photo (generally speaking). Some of the time you can switch the flash off, setup the self-timer, put it on a wall or a tripod and take a half-decent night shot. Which is fairly impressive considering how small the sensor is in relation to 35mm film. (The average compact digital camera sensor size is 7.2mm x 5.3mm (1/1.8 sensor), this is roughly 5x smaller than 35mm film, with an average Pixel area(µm2) of 2.6 – 3.8µm2) (Using a 12mp example: Canon Powershot G9 with a 1/1.7″ sensor, the pixel area is 3.8µm2). Example above taken with the Casio Exilim Z120.

On a side note: Do you remember when Digital Cameras were still new? Like in 2002 or 2003 when digital cameras were still so new that they had to write “Digital Camera” on the front of it somewhere so that you knew it was a digital camera? Simply being a digital camera in 2001 was so exciting and new that they simply used those two words together as a marketing tool / selling point for the camera. Now you’re lucky if you even have the model number written on it, and rarely do you find the manufacturer name on the back these days. (They used to always put the manufacturers name underneath the screen – like this). Now it’s more likely the be the huge number of megapixels or optical zoom or screen size that’s plastered all over the camera.

Night shot - Nokia N86

With a camera phone – most of them don’t have a real flash (maybe 1% has a real xenon flash (the Sony Satio is the only recent one) that is equivalent to the flash you find in a Digital Camera) – and the rest – if you’re lucky (or unlucky depending how you feel about it) – has an LED or a “twin” LED flash. The problem is that even with (or without) the LED flash, the camera’s just don’t cope with low-light situations. You can put the phone on night mode (if you’re lucky), put it somewhere steady^ and switch on the self-timer, and hope it takes a successful shot. The problem is that the sensors in camera phones are even smaller than compact digital cameras. They just can’t get enough light into the sensor, and that means in low light situations they produce crap noisy images that are over-processed so much that you’re lucky there’s any image left to view. Further problems are caused due to the small sensors lacking the ability to capture dynamic range, so dark areas are underexposed, and bright areas are overexposed, further reducing detail in images (the example above taken with the Nokia N86 – where’s the detail in the steps?). The latest 12 megapixel camera phone sensors made by Sony have a 1.4µm pixel size – which is again 2.7x smaller than compact digital camera sensors. (2.6mm x 1.96mm estimation). This is roughly 13.8x smaller than 35mm film.

In a nutshell – it’s all about the light – 35mm film cameras can absorb lots of light, and therefore take photos in dark conditions and get as much colour and detail as possible. Digital Cameras, more so compact cameras, have much smaller sensors and struggle in low light, but don’t do too bad a job of it thanks to having a flash, however, they are very much on the limit of acceptable image quality (that’s why Digital SLRs get better image quality – they have larger sensors). Camera phones on the other hand have had to miniaturize to the point where image quality is badly affected, and the only way to get good photos from them is to use them in ideal light, or have a real xenon flash for times when lighting is poor.

^ Options are limited as I don’t know of any camera phones with tripod mount, and you’re generally lucky if the phone will stand on it’s side without falling over. Even on the “Photo-centric” Nokia N86 8mp you can’t stand the camera on it’s side without it falling over!

Review: The Sony Satio 12mp Camera Phone – Re-visited (Phones)

Posted by – January 27, 2010

As a phone – it’s okay. It has a great screen (the built in videos are quite impressive) although it’s not as colourful as the Nokia’s OLED screen. Acceptable touch screen – although I’m not a big fan – so never really got completely used to (or happy) using this phone. The stylus seems quite loose – which has resulted in me loosing it once, and nearly loosing it a second time. The phone feels a little cheap – very plastic – although the sliding lens cover is quite nice and the shutter button feels decent. It’s interesting (and a little surprising) to see Sony ditch Sony M2 memory cards and instead include an 8gb Micro SD cards. (It looks like Sony are doing the same with all their cameras and giving the option of Sony MS or standard SD cards). What else does it do… find out below…

Review: The Nokia N86 8mp Camera Phone – Re-visited (Phones)

Posted by – December 29, 2009

Previously I was particularly scathing of the Nokia N86 8mp Camera Phone – but perhaps, after experiencing the touchscreen Sony Satio, and updating the firmware of the Nokia N86 – my experience using the phone has been a little more pleasant, and it seemed about time to post my re-evaluation of the phone.


Most of the issues originally reported still exist (and pretty much all of them are still relevant), but being aware of the limitations has let me work round most, sorry, some of the issues (and ignore or avoid the rest), until I can get a “real” smartphone (see Android phones), and finding 3rd party apps has certainly helped.

First of all you’ll need to install Opera Mini (version 5 Beta 2 works very well*) as the built in web browser is pretty rubbish, and data hungry. Another good app is J1CK.Tweet which is a simple and easy to use twitter app, with a decent number of features, such as letting you take photos and post them on twitter / twitpic (and then onwards to facebook if you use the facebook selective twitter app and #fb). See what I mean about needing to find a work-around or two?

You can also use Opera Mini for RSS feeds – but I haven’t found an app for this problem yet. (The built in RSS feed reader hides inside the built in web browser).

ISO100

The built in Sat-Nav software is still pretty annoying, and limited to 10 days of use. One feature you can use is the walking mode – and as long as you don’t drive over ~29mph – you can still use this as a handy navigation system when stuck with no other solution. (The N86′s built in Sat-Nav software is by Nokia, and called Nokia Maps – and is noticeably better than the Sony Satio’s bundled navigation software: “WisePilot” – when I first used it, it only had four locations available: Sweden, Germany, plus two other European countries, which were not much use when I was in the north of England!)

ISO100

There is still no facebook integration built in apart from the “Facebook app” – which is basically a shortcut to the website, and an icon. It uses the built in web browser, and the web browser still doesn’t accept email addresses with the subject defined after a ‘?’ question mark. You can get round this by adding an email account to the phone, and adding your facebook mobile email address to your contacts, or by using a 3rd party twitter app (see above). But it’s hardly elegant or particularly easy.

ISO100

Running too many programs at once is an issue – and by too many – I mean about 4 or 5 apps. Load up Opera Mini, Web Browser, Email, Music Player, etc and then try sending a text message to someone – and the phone will freeze, unable to open the text message page, and will give no error message, just an empty screen. You can go to each application and quit them one by one, but sometimes it’s just quicker and easier to switch the phone off and on again.

Battery life is still awful. The only solution to this is to carry a USB cable with you at all times so that you can charge it when you’re in front of a computer. If you’re staying anywhere overnight, you will need to take the wall charger, battery life is around 1 or 2 days. If you actually use it, the battery life is appalling.

ISO123

The battery life can noticeably affect the visibility of the screen in bright light – so it’s important to keep the phone charged at all times. The screen does look very good – the colours are very bright, the screen is clear and crisp, assuming the battery is fully charged – and the sun isn’t out. Although the screen does seem to scratch very easily.

ISO132 - Keep Off The Rocks” How about “No large notices?”

Since the last issue with ovi.com and their on-line services I’ve avoided them completely. However I’ve had to use the OVI desktop software – this is a big huge mess of an installation – centering around “Nokia Ovi Suite”. The most useful feature of this is the ability to plug in your phone and use it’s internet connection when yours is down, but the Sony Satio version of the software is much better, simpler to install and use, and gives you more useful information when connected to the internet. (The Sony Satio software is also easier to install, being cleverly stored on the phone, so that you can install it where-ever you take the phone, instead of the Nokia software coming on CD, or needing to be downloaded).

ISO107

The camera uses an LED flash, which despite Nokia’s claims of excellent low-light performance thanks
to the f2.4 aperture lens, just isn’t adequate for indoor shots of people. It simply isn’t bright enough when compared to cameras with a real flash (see DigiCamReview.com or the Sony Satio) and photos of people with any movement will come out blurry (see the examples below, these are fairly typical of the results you’ll get indoors). In fact it’s so bad that one nights photos with the Nokia N86 8mp were completely unusable – I took about 12 shots with the camera with flash, they were nearly all blurry, with poor colour, featured lots of red-eye, and were not even decent enough to put on Facebook (with it’s lower than VGA photo requirements). In comparison the same number of shots taken with the Sony Satio on the same night all came out well due to the Sony’s Xenon flash.

ISO100

Photos outside, in good light, can be pretty good. By pretty good, I mean good for a camera phone (see the examples shown – these are some of the better photos taken with the camera). I still think even the cheapest branded digital camera from Kodak (see below), Fuji, etc would be better than the Nokia N86. The macro mode is fairly good, but often the photos look a little washed out (lens flare?), and the camera is very sensitive to any dirt on the lens. Photos are still overly compressed and end up on average between 590kb and 1.9mb which is quite small for an 8mp camera (averaging around ~1.2mb).

Overall – this camera phone is pretty rubbish – but “acceptable” as a phone as long as you don’t expect too much of it. Don’t expect it to do RSS feeds properly or well (it needs a dedicated app for this), don’t expect it to do Facebook properly or well (ditto), and don’t expect it to do Twitter at all unless you get a 3rd party app. Most of all, don’t expect it to be a decent camera, simply because it can’t take decent photos indoors. The twin-LED flash solution, is just not good enough, and if you want a camera on your phone then you will need to get the Sony Satio with a real flash, or better yet, just get a cheap digital camera, such as the Kodak Easyshare C140 for £49 – it had a real 3x optical zoom lens, and a real flash!

After three months of use I’ve grown to accept the phone’s limitations – and grown to appreciate it’s design – I like the buttons, the sliding design, and compact size. It’s easy to text and phone people*, and the camera is acceptable in good weather**. But saying that, a dedicated digital camera is always going to be better, thanks to a real flash and better image quality – the images from the Nokia look over processed, and the colour seems poor generally. The phone works fairly well on the internet (better with Opera Mini) and is a decent enough phone if you don’t want to switch over to a touch screen, are a fan of Nokia, and you don’t expect too much from it. However, saying all this, it’s still pretty rubbish, and should have been, and could have been much better!

Pros:
Uses the new Micro USB connection which is now the world-wide standard for all mobile phones! Hooray!
Uses the standard 3.5mm stereo jack
Wide angle 28mm AF lens

Cons:
Satnav limited to 10 days navigation.
LED Flash (no substitute for a real flash) – doesn’t light subject well, but does create red-eye
Poor value for money (especially when new, as with most new contract mobile phones – £238 sim free)

* apart from the crashes obviously.
** assuming you don’t have a real digital camera with you.

Tested with software version 20.115.229.01, 21-09-2009. Face detection was added with the firmware update.

Fuji FinePix F70EXR Review on DigiCamReview (Cameras)

Posted by – October 5, 2009

Fujifilm FinePix F70EXR

DigiCamReview have reviewed the new Fujifilm FinePix F70EXR – it’s currently the world’s smallest 10x optical zoom digital camera and features a wide angle zoom lens (27-270mm), a 10 megapixel SuperCCD EXR sensor that provides high resolution, high sensitivity, and high dynamic range modes, an anti-shake sensor, 2.7″ screen, SD card support, 5 Film Simulation Modes, and VGA video recording at 30fps. The Fujifilm FinePix F70EXR is available from Amazon for £200

“The Fujifilm FinePix F70EXR was a little unexpected, so soon after the F200EXR, it’s thinner, yet has an impressive 10x optical zoom lens! As a compact camera it’s impressive that so much can be packed into a camera the same size as most other cameras only featuring a 3x optical zoom lens! Whilst the EXR sensor may not be as good as previous Fuji cameras for low noise, it does provide much improved dynamic range, especially when you would normally lose detail in the sky.”

Samsung ST50 Review (Cameras)

Posted by – July 21, 2009

Samsung ST50

The Samsung ST50 could be summed up by the writing on the front of the camera: it’s got an ultra slim 16.6mm stainless steel body, features “smart auto”, “beauty shot”, a 12.2 megapixel sensor and a 3x optical zoom lens. And that’s about as interesting as this camera gets. It doesn’t have HD video recording (max video resolution is 800×600 at 20fps), it doesn’t have any form of real image stabilisation (only offering digital image stabilisation), it has a 2.7″ screen and face, blink and smile detection. The Samsung ST50 is available for £136 in Black, Silver or Red, measures 94.2 x 56 x 16.6 mm, and weighs 121g.

Samsung ST50

Apart from the camera being very small and fitting very neatly in small pockets, the camera has a very annoying focal range where the subject has to be 80cm away from the camera in normal mode, meaning you’re always having to switch to macro mode so that you can focus on subjects that are between 10 and 80cm away from the camera, or alternatively leave face detection on all the time so that you can take photos of people! The camera has a macro button on the back of the camera, but it’s a little slow to respond, and the menu is even slower to access (this problem can be avoided by using the “Smart Auto” mode). The camera doesn’t feature any scene modes, so you can either use Auto and hope for the best, or try “Smart Auto” and once again, hope for the best. The Smart Auto mode will automatically select the scene mode it thinks is best, alternatively you can choose the “Photo style selector” in the normal mode, which gives you the choice of: Normal, Soft, Vivid, Forest, Retro (Sepia colours), Cool, Calm, Black and White, Negative, Custom RGB.
