Finally inspired by a recent post re: Cold Light v. Condenser and over-perspired from trying to burn in runaway highlights in too prints from "contrasty" negati ves, I am in the middle of converting my Omega D5 condenser head into a diffusio n source in the following manner:
I am placing a piece of diffusion material (flashed opal glass precisely measure d, cut round) in the bottom most part of the condenser assembly, so that it will be situated closest to the negative carrier. Then, because of the light loss f rom the diffusion, I am replacing the standard 75 watt bulb with a more powerful one (a 250 watt for starters, if this runs too hot, then 150 watt).
I am interested in hearing from experienced B&W printers who have made similar c onversions on your experience with it. How did you like the results vs. origina l set up, any drawbacks or other details to be concerned about, etc. Thanks. A ndre Noble
