Versa Light Box Learning
For Fingerprint Photography, the construction of the Versa Light Box (VLB) allows quick changes between several different lighting techniques. Examples are white opal light, dark-field lighting, underlight and episcopical light using a transparent mirror.
The LED light source for the system is a spotlight with lenses for projection.
The Versa Light Box is designed to be used directly under the AFIS digital camera (for direct scanning of the original fingerprint)and also in a small crime laboratory with a standard type camera.

Versa Light Box Parts
> Various light modes for photography
Here is a description of a typical light setup with a Versa Light Box and a camera.
You can photograph the evidence top on the box, in the box and under the box. The new Versa Lightbox is fitted with legs to make room for larger evidence under the box.
Mirrors for Episcopal Technique and Dark Field Lighting
You can switch to a transparent mirror or a regular mirror for the various usage options. Episcopal Technique, Dark Field Lighting Technology, Opal Light Technology.
On the left side, a transparent mirror, on the right, a normal mirror, and you can turn it to get the best light when it is installed in the Light Box.
Episcopic Technique.
Example, a fingerprint on a knife, mikrosil, gray plastic bag developed with superglue, photographed with the episcopic Technique. The fingerprints are placed under the transparent mirror for photography.
The light passes through the lens from the lamp to the transparent mirror, and you turn the mirror so that the fingerprint appears in the camera. The camera can now photograph the fingerprint through the mirror.
Dark Field Lighting Technology.
Fingerprint on a piece of transparent object. A fingerprint is placed on a clear glass plate for photography.
The light passes through the lens from the lamp to the regular mirror. The fingerprint is illuminated from below. Turn the mirror so that the fingerprint appears on the camera. The camera can now photograph the fingerprint.
Mirrors for Opal Light Technology.
For Opal Light Technology, we use a standard mirror which you place diagonally in the Versa Light box.
Opal Light Technology.
A brushed fingerprint is lifted with transparent tape and photographed with white opal light. A fingerprint is placed on a white opal board plate for photography.
The light from the lamp reflects via the mirror and lights up to the white opal board that makes fingerprints visible, and
the camera can now photograph the fingerprint.
> Example of an Episcopal Technique fingerprint on Microsil casting example
Here we have an example. We have a fingerprint on Microsil casting that we will photograph with the Episcopic Technique.
For the Episcopic Technique, we put a fully covered plate on the bottom of the candle box because it is a small object that goes into the box.
Hang down the fabric is there to block light that would otherwise be reflected in the camera. Hang it on the back side as the picture shows.
Place the Microsil finger print casting on the bottom of the Versa Light Box.
Put it into the Diffuser filter in the Versa Light Box, so that there will be a soft light.
Put the front lens plate there so that it concentrates light into the mirror.
Turn on the flashlight and aim the light at the center of the lens.
Look down from above at the Versa Light Box mirror and make a basic setting and adjust the mirror by turning the mirror so that you see the fingerprint clearly.
Then you have to adjust the camera and turn the mirror so that the fingerprint of the pressure appears clearly.
Here are the results we obtained with the Episcopal Technique of a fingerprint cast with a Mikrosil.

fingerprint on Glass
Here we have the same setup, but we have a fingerprint on the glass, it is a finger without brushing or any other influence which we will photograph with the Episcopic Technique.
Here are the results obtained on glass. It is a finger without brushing or any other influence and photograph with the Episcopic Technique.
> Example of an Episcopal Technique fingerprint on a Knife.
To photographing large objects that do not fit into the Versa Light Box or have difficulty placing the object, remove the bottom plate from the Versa Light Box.
We have one fingerprint on the knife.
And we have difficulty placing them in the Versa Light Box, so we place the knife below the Versa Light Box with a ground plate and magnet profile so that we can adjust the knife so that it does not reflect as much, and we also remove the Diffuser filter from the Versa Light Box
It can be difficult with shiny objects. But you can also direct light, on the side, at the top or, as in our case, it was best from under the side of the lens that you can see in the picture.
Here are the results obtained on a knife. It is a fingerprint without brushing or any other influence and photograph with the Episcopic Technique.
