I recently decided to “digitize” some of my moth collection. However, my Canon EOS 30D could not capture the level of resolution I was looking for.
Inspired by Joseph Scheer’s “Night Visions: The Secret Designs of Moths,” I thought I’d try to scan my specimens. My first several attempts were less then satisfactory so off to Google through which I found Jim des Rivières website, which includes a page on the techniques. With this information and some more fiddling the parts started to come together. The main point was to adjust the setting to insure that there was no clipping, at least of the highlights, since I was aiming for a black background.
At last the moment of truth; scanning the specimen at 4800 dpi. The first scan was rather useless since one of the wings had not lain flat, so I had to weight down the wings. After this minor snag and some time, the scanning was finished. The files ranged between 1.73 gb and 367 mb so editing took some time. After the usual post processing (straightening, a bit of contrast adjustment and some sharpening), I created quarter sized copies of the individual moths and stitched them all together, though not in any particular order.
Here is the final, though heavily reduced, image:
To give an idea of the actual resolution here is a 100% crop from the full sized scan:
