I finally got around to comparing the results of wet vs. dry scans. The link shows a much-reduced jpg of a scan of a 6x9 image captured on Fuji Astia and scanned at 4000 dpi (a boring shot from outside my front door). The scanner was focused on the white 'For Sale' sign text on the right of the frame, and the 100% crops are from the top part of the moped which is right of center. The wet scan clearly exhibits better flatness, but there is also improved contrast. I used Lumina fluid and supplies from Scan Science. Preparing the film takes a bit of practice, but I am getting better at it. And, for me, it's worth an extra 2 - 3 minutes (prep time should drop as my skill level increases).
