Current ADBC Cameras

 
Home
May 23 , 2007 Digital cameras for photoscreening must have the flash located near the lens and the ability to override the "red reflex reduction" feature. The camera must be able to focus on the subject in a dim illumination, and ideally can zoom so the face can have sufficient image resolution for subsequent refractive crescent determination.

Focus and flash settingsfrom about 6 feet are simple with Gateway DV-S20 since there is no optical zoom or focus and the flash is automatic in dim light without red-relex control. other cameras require override or select relative to red reflex. JVC and Nikon Coolpix S4 focus better on bright detailed target identical distance to subject, and then silouette the subject with zoom up to 7x-10x from a distance of 8-10 feet.
