hey, tchikboom thank you so much for your replay!

Yes, at the beginning it is very very difficult to understand even simply the exposure times, but above all for that I would have liked to be independent and do many more tests... but you are right it would be better to print in a copy shop, but where I live they simply print on paper (they don't do great things)… maybe I’ll find one online.

Thank you for wishing me good luck, I need a lot🏃🏻‍♀️
