Well if you have silver, the easiest way is to dissolve it in nitric acid then precipitate it with a bromide salt. You would then make an emulsion of that with gelatin.

Ok . . . Docberto . . . But I need more details, I think much more details. . .
How much silver and nitrate whats the relation. Ex. For i make 100g Silver Nitate ???
How I´m not a chemical, unfortunately I need details about to do, how to proceed, step by step. like a cake recipe.
I aleady got some material form internet, but all is superficial as much.
Thank You for while. ..

Your post is too vague to get any help.

What exactly are you trying to make? A science fair project?

Your name sounds familiar, U2U me in portuguese if you will.
