I know that that question may have a thousand answers and one thousand years of philosophic debate, but I ask, what is a good developer for pushing film? I now that possibly diafine types are the best or very good, but for immediate use, I only have TMAX and XTOL avaliable. I doing a work for a photo workshop and doing a bit of photodocumentary about a martial art training, so fast moving subjects and also low light, since the trainings are at 19:00 to 20H or more. I have tmax3200 and thinking of using at the box speed, or more, insted of iso 1600. So, what is best for it? XTOL (that is one of my main developers for BW) or TMAX Dev that I know several people like for pushing. Also, my question being narrow to this two is, that they are both avaliable here in Portugal and can have it in two or 3 days if bought online.
