I am not known for being a great specialist in film scanning. So, reluctantly I scanned some recent b/w negs on my Epson Perfection 1240U flatbed scanner today. It's TPU (transparency unit) is the only way I have to scan MF negs, my other 'real' scanner being 35mm film only (a Konica Minolta Dimage Scandual IV).
First one below is a scan of a Pentax 67 neg on Ilford FP4 in HC-110 (dil.B, 6 minutes), the second is one of a Bronica RF645 neg on Tri-X, also in HC-110. I scanned both at 1200dpi as 'color neg' because that gives less 'dirty' and less grainy results on the flatbed.
The only tweaks in PS Elements 2.0 were : conversion to greyscale, auto levels, slight luminance & contrast tweaks and finally some sharpening (unsharp mask).
Besides that I think the pics are not really sharp, they are grainy and dirty. I was wondering now if this had to do with a bad film/developer combination, a bad scanner or a bad workflow.
I had the same bad results last time I tried with 35mm negs on the KM Scandual IV, but that might have been because of the HP5/Rodinal combination (1+50, 15min.), this developer being famous for grainy results? See third scan for this.
Ideally I shold print each of these negatives in the enlarger and compare the prints with what I got on the computer screen, but my wet darkroom is in boxes... Thanks for any input and ideas on what is the problem here.
