I have made contact sheets of 35mm negs with base exposure of 20.2 seconds @f/11 without Filter.
Paper: MCP 312 semi-matte
Developer: Adotol NE - 1 min.
Enlarger: Focomat Ic.
Film: APX 100 and Fomapan 100 developed with Rodinal 1+50.
Contact sheets gave an overall idea about the print exposures and as well as neg exposures(APX is lossy compared to Fomapan).
Now I am curious about the effect of filters(atleast Grade 3) before I burn some more paper.
One thing for sure is it will affect the contrast but I wonder whether it will effect the base exposure too...if so, how much? Provided the height, the lens opening and other variables are kept constant.
