I found a site in my country that can deliver a lot from the Kodak catalog, and i had a little thought of trying Kodak chemistry. But i find this to be an informational mess, a real djungle. I cannot figure out what could be proper for a hobbyist like me, so i have not a clue what to order. The site: http://www.pcdoctorn.se/CBB.aspx?q=b:147;pl:1 If i search for Flexicolor or Ektacolor i get loads of different products with quite cryptic names, like "KODAK 8X3L FLXCLR SM TANK DEVR" or "KODAK 20 L FLXCLR RA FXR & RPLR". If i browse around at Kodak i do not find any useful info on what is what or what would fit my needs. So far i have only used Tetenal, that was a no brainer on what to order.. I develop film in a Paterson tank and paper in trays or tubes i roll on the table (those tubes i may be able to develop to something i can sell once i manage to make a decent light trap when changing and screwing off the chemistry holder). I need chems with long shelf life unmixed that can be mixed to working solutions in small quantities. The Tetenal concentrates goes bad in a month or two once opened, and i usually do not develop enough film to use it all up. I have even thought of making my own chemistry from raw chemicals, but there may be some Kodak product that i can use? What would i get if i order the "KODAK 8X3L FLXCLR SM TANK DEVR"? How long shelf life? How long shelf life has opened chemistry concentrates? How many films will 0.35L develop? Is it even concentrates? What???
