Using the Photo-Flash
The photo-flash allows optimal captures to be obtained in any environment with the highest quality. You can even take captures in a completely dark room and varying subject distances with no degradation of image quality.
Once the flash intensity is set for a given subject distance, all captures will be identical even with different amounts of room light.
The VALCam stores different settings for Flash and non Flash captures so both live and Flash captures can be obtained without user intervention.

Cropping Control
The VALCam USB allows the user to set cropping parameters for both preview and capture. The live preview will display live video that corresponds to these parameters. The capture image will also conform to these dimensions.
These parameters can be set to match the picture box of the card design thereby eliminating the need for software cropping and speeding up the capture process. The efficiency of the process will depend on how the photo-id application handles image captures.
Another advantage of this feature is that the live preview will correspond to the actual “portrait” design of the card for a more pleasing a realistic rendition of the image.
