A friend of mine who is an artist has put some put images (jpgs) of some of her collages on her personal website. As I understand it the jpgs were made by scanning slides; the photography and the scannning were done by a professional lab.
My friend is disappointed with the results and I sympathize with her: the images are not nearly as sharp as they should be.
Apparently the slides were scanned at 72 dpi; and the people at the lab told her there was no point in using a higher resolution for something that was to be displayed on a computer screen.
This all puzzles me (I know very little about "resolution" and that sort of thing!) For one thing, I've looked at a lot of photography blogs that show full-screen (laptop screen anyway) images that are *very very* sharp. If you can take a photograph of a building or a face and display it big and sharp on a computer screen why can't you take a photo of a painting or collage and get the same quality of result?
Thinking about this it occurred to me that the use of intermediary slides might be the problem. Slides are small so it's not surprising that when they're digitalized and then blown up it the results are blurred. Wouldn't it be better to work entirely from digital images as the photography bloggers presumably do?
Any explanations that would sharpen my understanding of any of this mysterious stuff would be much appreciated.
