I am having a difficult time determining the differnce between HC110 and Tmax/Tmax RS developers in terms of if they have any different effects on negative characteristics when used to develop Tmax 100 film. Also, how do the two developers compare when it comes to N+/N- development. From a convenience point I would like to switch to HC110 as the recommended temperature for N+/N- is 68 degrees which is the temperature in my darkroom and the Tmax is 75 degrees which means I have to go to alot of effort to maintain the temperature especially for tray development of sheets.

Thanks in advance.

Why don't you use T-Max RS at 68 degrees? Other than the times changing, I haven't found there to be any significant change in the characteristic curve shape between 68 and 75. I have been using T-Max RS at 68 degrees for years.

You may know this already, but TMAX developer is not recommended for sheet film. It causes dichrotic fog. Use only TMAX RS for sheet film.

hc 110 gives the tmax neg mushy big grain in my opinion, I've used it for a long time, but then tried tmax rs and wouldn't go back for anything--nice, crisp and sharp. I say stick to the tmax rs and adjust your times to suit you.

I've used both to develope Tmax. Regardless of what temp I use, I hate the results I get with HC11O.
