Hi Shawn, I had the same problem with Tech-pan. Using Technidol, I was developing at 68F for 11 minutes. My negatives too were sort of flat and required grade 4 paper to bring it up to par. This worked fine until I decided to use some Luminos Charcoal R, which is only available in grade 2 1/2. Selenium toning helped, but I never got the contrast I was looking for. Then I tried Photographer's Formulary TD- 3. This was my saving grace. Not only does it allow you to adjust the contrast level through dilution and agitation, but it also gives you an extra stop of speed for good measure. I still shoot at 25, but my neg's are denser now. The standard diltion gives me all the contrast I need to print successfully on grade 2 1/2 paper. The best part is that I'm still getting the micro-fine grain I need for 16x20 prints. Get some. It's what you need.(posted 9160 days ago)Good luck,
