So, my wand scanner arrived yesterday and I’ve tried it out already. I managed to do a decent scan of a page from the Na-Ga Rindou -rough note- book.
The top and bottom parts of the page did get cut off though, so need to watch out for that. I’ve tried scanning horizontally rather than vertically too, however that results in some of the margin being cut out. If you want to scan in a whole page, it seems you need to start just outside the intended area. That can be a problem.
Moire is a potential issue with scans too (and now I know the name of that annoying distortion my scans sometimes get! I thought they were called scan lines, but apparently not.) Flatbed scanners usually have a descreen option nowadays to prevent this kind of thing, it seems, but not wand scanners. It seems to be worse with higher resolution images (I think that picture above was scanned at 600 or 900 dpi)
This scan is somewhat okay, but it’s still not perfect, unfortunately.
Nyatsume Kyoudai box scans. Left is 300dpi, right is 600dpi. You need a very steady hand for scanning, otherwise you’ll get a distorted image. Distortion aside, quality is pretty good on 300dpi, can’t see any glaring signs of moire. 600dpi not too bad either. The box is glossy cardboard so that might just scan better than paper.
Horizontal and vertical scans from the book (300 dpi)… it’s really hard to scan smaller books without distortion. Works better for large books. And there’s the moire again. Yay.
In conclusion, I’d say it’s okay for making low quality scans but if you want the best quality scan you can possibly get… use a flatbed. It’s still a handy little tool to have if you want to scan something in quickly and aren’t terribly fussed about the quality.
EDIT: Okay, I may have been a bit hasty in my lambasting of the wand scanner.
I did another scan at 900dpi and compared it to a scan I had previously made with my flatbed scanner (I think that was 600dpi?).
As you can see, the difference isn’t really all that great. Heck, if I zoom in on my flatbed scans, I can see moire patterning anyway. Even those Little Busters Perfect Visual Book scans have moire patterning, though you have to zoom in to see it. Course, I have no idea what device the original scanner used… I’d assume flatbed though.
There is some difference with the lightning (I think I made the flatbed scan with my scanner’s Photo setting at the time. Don’t use it anymore.) and what seems to be slight distortion in the center of the wand picture. Something about it looks off compared to the flatbed scanner. Actually, my wand scanning was off a bit, whoops. Had to rotate it in Photoshop a little. Might just be the lighting playing tricks on me though…
So… yeah. Flatbeds aren’t perfect either. Maybe my flatbed doesn’t have descreening. IDK, I’ve never looked for it before… I really don’t know much about this kind of thing.
EDIT 2: Okay, I found the descreen option and did another scan with my flatbed.
Yeah, uh… there doesn’t seem to be much difference. e_e Ehh… maybe moire’s just something that’s almost impossible to get rid of completely.
I made another flatbed scan and followed the steps here: http://researchguides.case.edu/editimage/moire
Hmm, that actually seems to have worked pretty well. 😀 Okay, I’ll try doing that from now on.
Did the same with the wand scanner.
While the moire seems to been successfully dealt with… it’s still somewhat distorted and the lighting’s different.
In the end, the flatbed’s the clear winner.
