Hi, I have been scanning different size of filmsheet and prints lately and am experiencing some problems when I want to use the result for web-publishing.
I scan 6x6, 4x5" filmsheets and 4x5" contact prints at 900-1200 dpi to get a reasonably large tiff-file of say 50-90 Mbytes. I then import the file to Photoshop and resize it to be 600-900 pixels wide with rather good results.
When I scan an 8x10" print, I scan at only 300-600 dpi to get the same tiff-filesize, but when I resize to 600-900 pixels the picture seem to loose much more of sharpness than the 4x5" scan and also when I compare to the print itself. (It seems that the resize algorithm chooses randomly which pixels to keep, which in turn makes straight lines look blurry etc)
This is so disappointing that I hardly want to scan any enlarged prints and instead produce dedicated contacts to scan...sometimes I also dodge/burn the contact, and I do not like doing this artificially in PhotoShop.
Should I scan the 8x10 print at lower resolution to fit the websize from the start or do I need to step up further in dpi or...
I would appreciate some help in this topic. Thanks, Patrik.
