" I never change the tones of my negatives. I print them as they are. No burning and dodging, they are just as transparencies."
@Erik van Straten,
that's not how printing works. The second you put that negative into an enlarger, you're making choices. Paper finish and grade (or split-grade on MG), developer choice... all of them
change the tone of the print. Hell, even before that, when you chose your negative and developer, you were making choices that influence the finished print. If you think
your final print, regardless of what you do or don't do to it, isn't "chang[ing] the tone of [your] negatives", you're not only misunderstanding the process, but you're not getting the best out of your print.
The print I scanned and dropped into this thread a page or so ago was from a roll of XP2 I developed in Rodinal. I mentioned that I had to use a +4 contrast filter to get the right grade for the print - I knew that because I've printed from XP2 before, and I know the purple base plays havoc with contrast levels.
When printing from something with a clear base like either of the Rollei Retro stocks, I usually have to print around a grade 1, sometimes even using a pre-flash just to give a bit more detail to the highlights.
If I printed both of those materials the exact same way so I wasn't "changing the tones of my negatives", one or both of those prints would be truly bloody awful, and not reflect the actual image I took at all.
