RE: enlarger for scanning?
Maybe, but the enlarger has a focusing ability. I'd lay a piece of paper on the scanner first and focus the same way I would for an easel. Thus the projected image would be perfectly focused on the scanner glass. I'm reasonable sure it can't be this easy though or somebody would be selling this long ago. But I keep thinking all the scanner is doing is passing the light through from the top through the negative to the scanner sensor. How the scanner would react to nothing solid there though I'm not sure. Possibly the enlarger would have to be focused on the scanner sensor itself rather then the glass? Most likely I'm just spinning my wheels. However I'm hoping someone that has an enlarger at home will actually try this and report back to tell me how crazy I am! hint hint 8).

RE: enlarger for scanning?
Intersting idea. But why use a scanner. Would it not be possible to use a digital camera and a dedicated slide copier?

Re: enlarger for scanning?
He just scanned the test target instead of photographing it and scanning the film. His results are meaningless comparing them to the rest. Also note, without reading deeply, it seems that the tests also reflect the film and lens used by each tester. In other words like a lot of well meaning tests you can determine nothing from these as they are not sufficiently standardized. -- David Miers wrote: Has anyone ever tried using a flatbed designed for scanning negatives with a chemical darkroom enlarger?
