Dr5

Dr5

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 invented by David Wood, a photographer turned photographic chemist. The dr5 process is a chemical reverse process rather than the standard 'light reverse' for B&W transparency.

History

dr5, the 5th incarnation or the process, by experimentation. Though reversal film processing is commonly known, the dr5 process is unique both in recipe and procedure. The process is proprietary by Trade Secret. Done privately until 1998, the process teamed shortly with A&I [A&I's website is [http://www.aandi.com here] .] labs in Los Angeles CA [" [http://www.rangefindermag.com/magazine/archives/Jan05/labpro.tml Lab Profile: dr5: B&W Chromes Reborn With Proprietary dr5 Process] ", "Rangefinder," 2005.] .
