Sharpness and Grain…Diafine Processed Films Compared!

Here is something which is pretty straightforward and yet VERY interesting….a simple test target made by me to determine film sharpness and grain when processed in Diafine:

  • Lens to subject distance 55″
  • Leica M7 with a 90mm Elmarit F2.8 shot at F8
  • On a tripod with cable release.
  • Lighting, Wescott Spider Lights (5500 K)
  • All scan done on an Imacon Scanner (Wet Mount) 6300 optical dpi, 16 Bit.

Just click on the images below and check out the enlargement…the full size image (these are 35mm scanned negatives btw) would be 16″x 25″ at 360 dpi (optical resolution). No sharpening has been applied to the images but I did “try” to make them look as good as possible using levels and a little (I must stress the word little) noise reduction.

So what are your thoughts!?

  1. Funny, the apparent grain in the tmax-400 seems to give it a sharper feel. I assume it’s the contrast of the grain that gives it that “pop.” Great articles, but the way! I’m going to run out and buy some diafine ASAP.

  2. Gotta say that considering it was shot at EI 1250, Tri-X looks awfully good.

    Acros looks like it could use a contrast bump, but it’s nice and smooth and grainless if you like that sort of thing.
