Dr5
Encyclopedia
dr5, or dr5 Chrome, is a reversal black-and-white
process, via which most kinds of black-and-white negative
films produce transparencies (slides). It was developed by David Wood, CEO and proprietor of dr5 Chrome Lab, a photographer turned photographic chemist. The dr5 process is a chemical reversal process, rather than the standard light-based reversal for B&W transparency(black and white slide]. David Wood recently contributed to the acclaimed Darkroom Cookbook.
. Done privately until 1998, the process teamed shortly with A&I labs in Los Angeles CA. The dr5 process won best new product in 1999 at the '99 Photo Expo-Plus Expo Review In 2001, dr5 opened an independent lab at 38th and 8th in New York City. The lab used a processor made to dr5 specifications by Tecnolab in Italy
. The dr5 lab relocated to Denver Colorado in 2005.
