I have to burn a couple of papers in order the find out the exactly exposure time for a single foto.
To save paper I usually get a sheet and cut in 4 or 6 peices depending on the size.
I wonder if different papers have different time exposure or not. So I could use a cheap paper to test and use the expensive one to actually make the final print.
I have only used 1 paper so faz and now I am going to use Ilford ART 300.
