1:1 Adapter Light Diffuser

The 1:1 Adapter lens is a useful and convenient tool for the photographer who has the responsibility of recording evidence, especially fingerprints, blood stains, blood spatter, small entry marks, etc. The Lucite cylinder screws into the filter threads and holds the camera the correct distance from the item you are about to photograph while the built-in Adapter Lens lets you take 1:1 ratio photos of the evidence with your camera's normal 50mm or 55mm lens. The Lucite cylinder serves as a camera support.


One problem you may encounter in using the 1:1 Adapter Lens is at a crime scene when you are using a flashlight as a light source. You will get hot spots in the photograph.

The solution is to cut a section of plastic milk container to make a diffuser to place inside the Lucite cylinder.

The diffuser is cut out of a one gallon milk container. Mark out a section 5 3/8” by 2 1/8” on the side of the milk container and using scissors cut the plastic section out. Roll the plastic and insert it into the Lucite cylinder. You now have a diffuser that will soften the light eliminating the hot spots.

The clear Lucite cylinder will allow you to illuminate the area through the cylinder, if needed. This works very well on latent fingerprints and entry wounds. This will also work with an ALS using an amber lens .

The 1:1 Adapter Lens can be purchased from crime scene supply companies for $62.00.
