I just thought you were judging that I was going to try to use an specific paper without have trying and practice with other papers before.
I have being print for only 2 months about but I have printed hundreds photographs already.
As I said, I know that some of my questions sound silly. I knew that there is no paper which will have the exactly same time exposition and development. But since I am not a master who know everything, I gave a chance to see if somebody have found a solution to save paper based on their experience.
I actually printed for the first time on ART 300 today and love it.
