I have been experimenting with D23 at 1+3 and rotary development in home made BTZS style tubes, rolling them slowly and gently in a tub of water.
I intend this thread to be a resource for Times, Temperatures and experiences doing the same.
I am finishing off my last package of Kodak Tmax 400 (which I will post about in this thread). After that film is gone I plan to use HP5+ (which I'm already using in 120 roll film). However, I acquired 175 sheets of J&C Pro 100 4x5 at an incredibly good price so will be using that up first. I will post my experiences with HP5+ and JCPro 100 when I have reasonable experience with them in D23 1+3. (I have mostly used those films with Pyrocat HD at this point)
