I just purchased the Casio Color wrist camera. As far as I can tell, the wrist camera has a long way to go before it can acheive acceptable result. You have to be indoors and with absolute perfect reflective light conditions in order to see your image in the LCD display.
It has 3 exposure settings. Outdoors, Indoors, & Dusk. I find that only the Outdoors and Dusk setting (High Light and Low Light) are effective. The only way to get some decent results is to have plenty of light, set your Watch Camera on a solid sound surface and use the 2, 5, or 10 sec self-timer to trigger the camera. If you are facing anywhere close to the light source, be sure to shade the lens with your hand!
A. The LCD is not active matrix and therefore you can only use it for telling time! You can not see the image properly.
B. The speed is slow, so absolute still is required!(pressing camera release on your wrist!...come on now!)
C. Buy the Casio EX-Z3! Super camera and just strap it to your wrist!!!!
