OK here is a selection, I made sure each of these has small dust fragment to deblur as well. You can see the smearing around the dust. These are 16bit tiffs.

These are all taken with 4800dpi flatbed which is almost the start of the art that can be easily purchased new… These don’t really compare with something dedicated but they are still useful, and could certainly benefit from some enhancement so perhaps a good challenge… This scanner uses pixel shift; two rows of pixels at 2400dpi in the X dimension and the stepper motor that steps in increments to match 4800dpi. It has a wide angle lens with hopefully enough depth of field to cover the film. When you choose the lower resolution you can’t be sure exactly what the scanner does to achieve this lower resolution.
These are some of the settings that seem to give good results:
for the 4800dpi scan: RL radius 2, amount 100 damping 50, iterations 30
for the 2400dpi scan: RL radius 1, amount 100 damping 50, iterations 30
then resized and USM (using the RT defaults)
