I am a beginner with b & w printing and have the following problem, (if it is in fact a problem). I am using FOMA paper (Fomaspeed Variant RC glossy). I am trying to ascertain the exact exposure time to achieve a solid black in the paper. I am doing this by doing contact prints of clear film at different times. I notice that as the paper dries the faint greys on the paper seem to become more black to the point where they disappear and the whole paper simply looks solid black. E.g. if I do a contact print of clear film for 13 seconds at f11 I can see (faintly) the outline of the film while the paper is wet but once it dries the whole sheet looks uniformly black, (to my novice eye).
Any advice about this would be much appreciated.
