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.[1] The dr5 process is a chemical reversal process, rather than the standard light-based reversal for B&W transparency.[1] David Wood recently contributed to the acclaimed Darkroom Cookbook[2].
History
The dr5 process, the 5th incarnation or the process, was arrived at by experimentation. Though reversal film processing is commonly known, the dr5 process is proprietary by trade secret. Done privately until 1998, the process teamed shortly with A&I[3] labs in Los Angeles CA.[4] The dr5 process won best new product in 1999 at the '99 Photo Expo-PlusExpo review. In 2001 dr5 opened an independent lab at 38th and 8th in New York City[3]. The lab used a processor made to dr5 specifications by Tecnolab[5] in Italy. The dr5 lab relocated to Denver Colorado[6] in 2005.
