Tech notes: Mamiya RB67 with 65mm K/L mm lens. Kodak TMAX 400. Developed in Kodak TMAX developer, 7 minutes at 70F. As the weather and foliage changes, I am going to modify the development time. I'm losing mid tones because of all the identical green. The 7 minutes is not helping because it gives a little push. This helps with underexposure or shadows but at the expense of mid tones which are already flat. The whole idea is to expose properly and develop accordingly.
