Excepting slide photos. No real adjustment once taken (a more difficult medium than negative film which you can adjust a little when printing)

You’re right about Ansel Adams. He “dodged and burned” extensively (lightened and darkened areas when printing.) Photoshop kept the dodge and burn names on some tools for a while.

When we printed for our college paper we had a dial that could adjust the printed contrast a bit of our black and white “multigrade” paper (it added red light). People would mess with the processing to get different results too (cold/ sepia toned). It was hard to get exactly what you wanted and I kind of see why digital took over.

One might argue that there, many of the processing choices are being made by the film manufacturer, in the sensitizing dyes being used, etc.

I found one way to "adjust" slide photos: I accidentally processed a (color) roll of mine using C-41. The result was surprisingly not terrible.
