This is a great site. I'm glad to see such good results from old film. I recently aquired 25 sheets of 4x5 Tech Pan which is about 25 years old. Now I think I'll play around with it.
The questions is what developer to use. I picked up about 12 packs of the powder Technol developer for 25 cents a box at a close out sale. I heard somewhere to use the powder only for 35mm Tech pan and not for Roll film. Also I do have a few packs of the liquid version and I assume thats the one to use for the 4x5. Has anyone tried to use the power with roll or sheet film. Does anyone know why they don't recommend the powder for 120 or sheet?
Lastly I know that if you're not careful with this stuff your film will be extremely cointrasty. Any suggestions for getting the gray value up?
