I have a couple of film developer combinations I do not like, by starting with a developer I just cannot get decent results with TMAX developer no matter what film I use. I hate the results.

OK for films, Agfapan 400 developed in D76 or Rodinal...ecch but Agfapan 100 is a different story. Kodak D3200 developed in anything. And last but no least 2 films from China called Shanghai GP3 and SHD-100. These are aold thick emulsion films taht work great in Pyro but the quality control is terrible and actually has dust and stuff stuck to the emulsion

Thats it from me
