The first has formulae for RA4 roller transport compatible Developer and Blix. If you are tired of having commercial kits go bad in storage, or simply having a hard time getting kits because your local camera store has become a computer and peripheral shop, see: http://www.people.fas.harvard.edu/~keirst/technical.html Also I have a second page for Jonas Palm's Room Temp RA4 developer from which I derived my formula. See: http://www.people.fas.harvard.edu/~keirst/technical-jp-dev.html for his original recipe. I have not actually tried it because I have a roller transport processor, and so I don't do any development at room temp. Most of the chemicals are available from <http://www.artcraftchemicals.com/>Artcraft Chemicals. I get Etidronic acid, Diethylhydroxylamine and Triethanolamine from <http://www.sigmaaldrich.com/>Sigma-Aldrich Chemicals. -- Steve Keirstead Photography, Website: http://www.people.fas.harvard.edu/~keirst/ Steven Keirstead Photography 148 Worcester St. #5 Boston, MA 02118 Work Phone: (617) 495-2683 (Harvard University Biology Teaching labs) Home Phone: (617) 247-8164
