I used to shoot a lot of t-max but I was sending the film to a lab to get developed. I developed some myself in D-76 and the neg's turned out pink and it killed my fixer. It's my understanding you need t-max chemistry to do it right?
here is the deal...you have 2 basic black and white film grain types. This is referring to the actual grain in the halide. Its almost like binary code...on or off...
There is panchromatic and T-grain.
Tri-x is pan film along with ilford's x and hp series film...
tmax is like the ilford delta grain.
t-grain is already a "fine grain" where as the pan films are more based on contrast.
d76 and hc110(which are similar, but hc110 much better to use and has more subtle character to the shadow/highlight on good paper).
rodinal is a fine grain develper..
t-max is fine grain, but only made for the t-max(im sure others have tried it elsewhere).
If you use rodinal in high contrast tri-x you get some of the grain(although fine and beautiful) of tmax, but the higher contrast latitude of pan film.
T-max with rodinal is grain X2...meaning it will be really grainy and kinda spotty.
this picture was tmax 400, i ran it through some rodinal for fun before i sold off my darkroom equipt and then used my film scanner(cleaned it up a tad in PS as well).
it doesnt look like i have much if any film images on my flickr thing....but i have some great shots on LSD in chicago i did in 4x4.5 on plus-x(125 iso) developed with rodinal.
