OK folks, this is a first test<\/strong> of the iPhone 4s camera app<\/strong>.<\/p>\n

I shot the following photos in our garden. The goal was to test how professional the iPhone 4s camera app really is.<\/p>\n

Test iPhone 4s Camera: Aperture<\/h3>\n

Selective sharpness in macro mode or should we call it close up photography works great. The physics are limiting blur to the close up mode. We won\u2019t get great selective focus in portrait photos. I hoped for this when I heard about the great aperture of the iPhone 4s Camera. iPhoto showed me a fixed not changing aperture of f2.4. I don\u2019t know if we could rely in this. But this is of course a big step forward.<\/p>\n

Test iPhone 4s Camera: Shutterspeed<\/h3>\n

The shutter speed varies from 1\/60sec, in dark light, to 1\/120sec in normal light up to 1\/3954 in rare highlight situations. But this is no guarantee for a sharp photo. The autofocus is not very precise with moving objects in close up mode. And the time to release the shutter is fast but not fast enough for moving objects like playing children. But it fires like a machine gun.<\/p>\n

Test iPhone 4s Camera: ISO<\/h3>\n

Not much changing here. Most of the time it uses ISO64 outside. I only have one photo shot in ISO100. But I couldn\u2019t recognize any noise outside. Inside it goes up to ISO640 with some noise.<\/p>\n

The build in retouching function of the iPhone 4s<\/h3>\n

The auto enhancement is fast but not very improved. You will soon miss selective retouching. But it is a quicky for sending a photo on the road. Keep in mind that retouched cropped photos can\u2019t be restored after importing in iPhoto. The retouched photo can only be restored in the build in retouching function. So I strongly recommend third party apps like snapseed. The HDR function seems to be the same like on the iPhone 4. I will test it in a better environment soon.<\/p>\n

 <\/p>\n

This is my summary of the iPhone 4s Camera Test:<\/h3>\n
