I'm confused when people talk about scanning at 11, 6 or whatever 3 microns.
As some of you know here by my previous questions etc I have a Scanmate 5000 drum scanner and I have been trying to get the most out of Portra colour negative film and black n white film during the past year.....
I have no idea about microns and how it applies to the scanmate can anyone explain?
I understand there is a relation between the film used and the final size of the scan and the resolution you scan at to get the best quality.....
e.g to get the best scan for a final size of 32cm from a 6x6 film I scan at the enlargement required and around 2200dpi for a file size of about 100megs give or take for a 16-bit rgb TIFF file (in the case of Portra)
In my tests I have not found scanning at 4000dpi with the massive file size it gives not really being an advantage.....
What I have found is always scanning over the resolution needed and downsizing the image always results in a better image.....for example, if a scan of a 6x6 to the size of 32cm for a final result of 300dpi for use in a magazine gives me a certain resolution to scan at I always scan higher so I can reduce the image to get rid of extra 'grain' i see.....
