Still vs Video ... are the cameras on iPAD 2 adequate?
Photography 101 for the uninitiated.
Perhaps a bit of psychology. With still digital photos, as resolution increases so does the detail. We all love sharp, crisp detail. In stills, we study every detail and can get critical depending upon our need for perfection. There are a lot of other factors, but not here, and now.
What is video ... it is a lot of stills, being rapidly presented at a rate faster than the human eye and brain system can follow. As the speed of change increases and if there are slight differences from one frame (stills)then our brain takes over and it looks to us like it is a continuous scene. Here we can tolerate a bit of lessor detail because we concentrate and are focussed on the changes. Early projectors ran around 18 FPS. Obviously 24 FPS is better.
IMHO, Apple chose to support the FaceTime feature which is a video sharing service between various Apple products. The iPAD2 camera system provides reasonably good video for sharing.
The front camera of course focusses on the originator, and the rear enables sharing of the view of what the originator is viewing.
I doubt Apple envisioned using the cameras for still photography ... IMHO... hope this helps clarifies a bit.
