Apple IPhone 3GS Review: Same Clothes, New Feel: Camera, Video Recording

3 MegaPixel (MP) touch-focus capturing camera with video

Apple iPhone 3GS capturing camera has been upgraded to 3 megapixels only - probably to haged the waistline of the 3GS down. Yes, it sound kinda lame having only a 3 megapixel snapper on a high-discontinue pricey device, but still Apple chose to go for only a diminutive megapixel upgrade here.

But most importantly beside the more megapixels, there's now touch AF and video recording.

The touch AF works very quick and accurate. It even tracks moving subjects after you tap on them with a finger.

The capturing camera user interface is more than simple - the only controls are the camera/recorder key and a small thumbnail in the corner that shows the last taken photo.

The capturing camera quality is ok actually. Colors seem balanced and the image is nicely sharpened with relatively fine reproduction of details.

An easily visible drawback however is the high noise level - just see for the grainy effect found all over. That amount of noise is way too much even for a mobile phone camera. The only fine thing about the noise is that the luminance noise is much more than the nasty chromatic noise, which usually takes the shape of variously colored dots across the photo and is much more nagging. Plus the noise on these photos has some nice pattern, which adds for subtle analogue film-like effect. But it's noise after all and it's there on all photos - even those made in colorful daylight.

So in the end, we've seen better 3 megapixel cameras on phones, but the iPhone 3GS does alright. It's only that some users would have preferred a higher megapixel count. If LG can fit a 5 megapixel capturing camera in the 12mm LG Arena and an 8 megapixel one in the 12.4mm LG Viewty Smart, then it shouldn't bother Apple fitting something more substantial despite the thin 12.3mm iPhone girth. So we guess, it's a marketing decision after all - you know, probably something along the lines of "haged the specs down so we can upgrade more easily in the future". Hardly a user-friendly approach, we know, but it seems to do the trick for Apple.

Here are several Apple iPhone 3GS capturing camera samples:

When they announced all the "sizzling" capturing camera features of the recent iPhone 3GS the guys from Apple also threw in the magical "improved low light performance" line. If you know us, you'd do know that we live for lines like that. Disproving high-flown pitch phrases is the most fun part of our job. But again, the best times are when marketing has not lied but we indeed see improvement of any sort. So we organized an impromptu low-light shootout among several handsets, none of which is well-known for its low light performance, just so we check whether the iPhone 3GS is any better than the 3G.

INDOORS: Low light samples without flash - full resolution:

iPhone 3G (2MP) • iPhone 3GS (3MP) • HTC Touch Diamond (3MP) • LG Arena (5MP)

Since objectively judging image quality based on full resolution samples produced by cameras of different calibers will be a daunting task to anyone, we decided to hold them all and downsize them to a more appropriate 2 megapixel level. If you haven't noticed up so far, downsizing images actually hides excessive noise, so no one of our competitors should be in a disadvantageous position. Besides the Apple iPhone 3G of course.

It’s laughable we should say that, but quite subjectively the results by the iPhone 3G are our favorites. If anything else, at least it's easy to spot that the iPhone 3GS doesn't offer superior results to iPhone 3G. So, that's done, here's another high-pitched copy busted!

INDOORS: Low light samples without flash - downsized to 2 megapixels:

iPhone 3G (2MP) • iPhone 3GS (3MP) • HTC Touch Diamond (3MP) • LG Arena (5MP) • Crops

OUTDOORS: Low light samples without flash - full resolution:

iPhone 3G (2MP) • iPhone 3GS (3MP)

Finally it comes the time for our studio resolution chart. This is a standard ISO12233 chart used for evaluating the synthetic resolution of digital cameras. It is an excellent tool for measuring pure horizontal and vertical resolution and also offers a fine reference point for comparison of resolution between cameras.

The long parallel lines serve as fine measurement of resolved resolution. The point where the lines are no longer clearly separated is where the resolution resolved by the capturing camera maxes out. There's a number scale alongside so you can even set a number corresponding to the camera's performance.

The several different line sets are taken from various places across the frame so you also have a nice representation how the image resolution changes as you go towards the edges of the frame (poor optics are far blurry towards the frame ends than in the frame center).

We also have some grey and color test charts stuck on there - those show how the noise suppressing algorithm affects the various colors (usually different) and how the algorithm affects the detail in the shadows. Usually with a poor capturing camera you can't distinguish any incompatibility in the shades of black, while in reality there is some.

iPhone 3GS records video in Video Graphics Array (VGA) resolution at 30 fps. The .MOV file format of the clip shouldn't surprise anybody we guess. The video quality, colors and contrast are relatively ok. The iPhone 3GS could benefit from some sort of digital image stabilization to haged handshake under control.

An fascinating drawback to video recording we experience and successfully recreated on several occasions includes the audio recording unexpectedly cutting on us when shooting in loud environment (say, a night club). Yes, shooting video with the iPhone 3GS in really noisy environment such as a night club makes the capturing camera stop recording sound at its whim - for no particular reason, whenever and for how long it decides it's appropriate.

Video clips are stored in the capturing camera roll and are indicated with a play icon. They can be sdiscontinue via email, MMS or can be directly uploaded to YouTube.

YouTube video uploading is a snap and it even works in the background allowing you to shoot more videos while you upload the first one. There are some limitations to it. For instance, the maximum duration of uploads should be no longer than 10 minutes. Also YouTube resizes the video files to 480 x 360 pixels and at least for the time being the recompression outputs quite pixelated videos, perhaps YouTube will optimize their encoding for the iPhone uploaded videos to achieve better quality.

Playing and sharing video clips

The recorded clips can also be trimmed. When in editing mode, the video is shown in filmstrip line, surrounded by a yellow box. After positioning the beginning and discontinue of the trimming zone, the clip is ready for precise editing. You simply have to hrecent your finger down on the yellow box to activate the precise editing mode. There is a play button for quick preview as well as a yellow Trim button for saving the result.

Unfortunately, at least until iPhone Operating System (OS) 3.1 doesn't create it to the scene, saving a clip after editing it WILL OVERWRITE the original video file. Quite a nuisance, we know!
