When first putting up Adventures images for the wiki, I scanned them at 300 dpi. Essentially, a little lower quality, for a couple reasons. 1) It scans faster and 2) It's a lower resolution, so if any lint or hair or dust or whatever gets stuck on the card or the scanner, all it takes is a couple eyedropper/pencil strokes in paint to pretend they never happened. However, the images look a bit "washed out", particularly some of the cards with art that has a lighter background.
When I was rescanning Prosperity and Adventures cards, I scanned them at 400 dpi. This was definitely a higher quality image where you could see details better, but 1) This makes it scan longer, and if there's lint/dust/whatever it takes me longer to deal with it, or else I have to wipe everything and rescan and 2) They look like newspaper cutouts for some reason.
Maybe it's just my shitty scanner, but I can't seem to scan cards so they look like the images on the wiki for Base through Alchemy.
So I'm leaving it up to you people - which do you prefer? Is "washed out" fine, and I can call it a day? Or would you prefer "newspaper", given that it looks better and fits more with the other scanned cards? I don't mind rescanning, just don't expect it to be done tonight.
