It may be necessary to compare various study photographs over different time intervals. This information may be required by the study sponsor for various reasons. Further, these photographs may be used in objective or subjective evaluations of the efficacy of the test product.

This instrument and its software have been specifically developed to take high resolution full face (left and right side views) photos under standardized conditions for the documentation of treatments and studies. Stable, long lasting and extremely homogeneous illumination of the face by white light LEDs, without developing heat, and a high resolution reflex camera integrated (18 mega pixel) with a special objective, allow for detailed facial photos. Photos are organised systematically and detailed comparisons are possible over various time intervals.
