I am just starting to develop my own BW films. It is very satisfying to have total controls of the entire development process. What do you think of these 3 shots here? Do you think the water temperature may have been too warm or too cold? These are developed using Kodak d76 at 68f, supposedly. I was having issues keeping the temp constant during the rinsing part. I was following the instructions from here.
Mamiya c330, sekor 65mm with a yellow filter. Tmax 400. Scanned by Canon 9000f.

This shot was from another roll tmax400 and D76 and pushed by 2 tops.
