Mirror Technique For the Recovery of Impressions from Light-Colored Floor Surfaces

FOR ADDITIONAL EVIDENCE PACKAGING SEE: Evidence Collection - Section 1 Evidence Collection - Section 2 Evidence Collection - Section 3

BVDA Gelatin Lifter Mirror Technique
	Position a mirror standing on the floor to be examined. Use a high-intensity light to create oblique illumination across the open floor. The path from the light-source to the mirror must be diagonal, at an angle of about 30 degrees in relation to the mirror surface. Aiming the light source directly into the mirror is not effective.
	Adjust the angle of the mirror and the light source until the impressions, if present, are visible in the mirror. The resulting visible impressions can be seen in the mirror, while they are still invisible on the floor surface. Using the mirror image as your guide, mark the toe and heel ends of the impression, two lasers are used in this demonstration (other markers may be used such as adhesive photo scales, permanent marker, etc.),
	After marking the location of the impression a Gelatin Lifter should be carefully used to recover the impression. Hold the Gelatin Lifter by its two short ends and apply it so that the impression is completelty covered. Remember to apply the Gelatin Lifter from one end to the other in order to reduce or eliminate the occurance of bubbles.
	After using a clean ink roller to completely remove any air bubbles from the Gelatin Lifter, the shoe impression can then be lifted. EVIDENT reccommends photographing the lifted impression immediately.
