I am working with 120 format negatives, shooting with a heavy tripod, and I want to get results that are sharp, fine-grained, with good tonal separation, particularly in the shadows. Sharp definition is my highest priority, and to that end I have been using Rodinal (generally in 1+50 dilution) to achieve that. So far I have tried Ilford Pan F+, Efke 25, and Fuji Acros. All look pretty good if properly exposed, but when enlarged to 16 x 20 none of them look better than 35 mm Adox CMS 20. Are there other combinations I should be trying?
