It is a negative film at size 6x7cm|||Film negatives don't have a resolution per sais only when the film is digitized does PPI (Pixels per Inch) resolution come into it. Your printer will use DPI (Dots per Inch), PPI and DPI are NOT the same thing.
Chapter and verse on scanning Wayne Fulton's site here
http://www.scantips.com/
Basically you set the resolution of the scan for output i.e. the resolution your print size needs, rarely at the highest resolution your scanner is capable of.
An easy way to work out this resolution is to work with file size. 1Mb of file size per Inch of print on the longest side guarantees a good print. As an example a 10" X 8" print needs a file size of ~ 10Mb, a 20" X 16" needs ~ 20Mb. What you are doing by this method is matching the 'grid' (pixels across X pixels down) of the scanned file to the 'grid' the printer is going to lay down, optimizing results and avoiding unnecessary file size which just gets 'interpolated down' i.e. 'dumped' excess data by the printer driver if it's too big, or, worse, 'interpolated up' if it's too small.
Chris|||Film is film and has no pixel resolution.
Get the finest grain 120 film and then once you have had it developed, scan in just those you want to convert into a digital file. Scan at the highest resolution for best results
Can we assume that you have a scanner that will scan 120 film with 6x7 cm frames?|||Have it scanned with a drum scanner. Either send it in to a commercial shop or spend the big bucks and get your own. These are not cheap but if you want to get the quality then you can.
