How are you capturing your images?
Film Camera, Digital, Video?
What specific make/model?
We are experimenting with our RUVIS and are trying to determine the best possible image capture method, and thought that somebody out there must have some tips and tricks.

Andrew, I have used both film and digital for capture, digital with Kodak/Nikon DCS Pro/SLR N, 60mm micro nikkor 1:2.8, I used the full manual mode, exposed at the meter recommendation and achieved consistant results; then moving to Photoshop. For film, I use Tri-X or Ilford B & W, shot at the rated speed, developed with Rodinal 1:25 or 1:50 6-12 minutes depending on the contrast of the ridge detail. One of several 35mm cameras are used, all full manual mode. A step up/down ring will be needed, which depends on the lens used. The RUVIS system was here when I was hired, have not had much/any luck finding actual casework ridge detail that could not be seen with normal white light searches. Most multi-colored background work is easier with film and filters or scan to photoshop.

we use the Sirchie Krimesite Imager (an older model). We went down to Sirchie's beautiful facility in N.C. to be trained, and we were taught to capture the image on digital, then take certain steps in photoshop to size it 1:1 and manipulate it into a grayscale image for easier comparison to inked impressions. In actual casework, I was only able to secure one latent which was not otherwise obtainable with powders. Mostly we utilize our RUVIS as a large area search tool...
