Hi there,

I'm interested in trying divided d-23. There are a lot of formulas online and I'm not sure where to start. Currently I'm using HP5, and Arista/Foma 400 but I'm going to try TMAX 400 in 35mm also and might try it in 4x5.

I assume I'm going to have to buy the chemicals in bulk?

I'm guessing that DD-23 would not be a good high speed developer? I'm going to try TMAX 400 for my 35mm with the hopes of pushing it pretty hard, so I think I'm going to stick with XTOL or possibly Microphen for that and then maybe DD-23 for my box speed shooting.
