Jack: You first need to determine the real (not the Manufacturers) film speed. Once that is determined, you can use that info and procede to further determine the proper development time for the various Zone issues. Send me an E-mail at benchemist5@hotmail.com and let me know what film and developer combination you're using. Don't do anything just yet with the camera and film. Forget about drilling holes in dark slides. I'll give you a better method |
