'scanning' negatives with digital camera
Here are some hints when 'scanning' negatives with an Olympus OM-D EM-5 digital camera with 60mm macro lens.
Film
Camera
Largest ratio for sensor (3:2)
Base ISO (200)
IS off
Sharpening & Noise filter off
Whitebalance (white) in camera on blank film

Flash
Adobe Camera Raw
Adobe Photoshop
Notes
Aperture of lens did have great effect.
Photographing emulsion side had a marginal effect (better).
Stacking 10 imgages did not reduce noise, so it probably is grain (clusters).
Noise filter didn't have a real effect (leave it to off).
Green channel from raw file gives most detail.
