Is the EPSON 4990 really 16 bit?
Hi, after comparing 8 and 16 bit scans of 6x6 transparencies with the Epson 4990 and Epson scan 2.61G by thorough examination of the scans with photoshop with respect to posterization in highlights and shadows, I can't see any differences between the two bit depths. I scanned with Epson color calibration as ... 15 Feb 2006 14:59

Want to scan old family photo negatives
Hi. I would like to scan old family photo negatives. I have the photos themselves, but a lot of them are faded, creased, etc. I also have negatives for a lot of them, too, so was thinking of scanning the film negatives so I could get a pristine/new electronic file and print. The thing is, I don't know what sizes t... 20 Jan 2006 21:15

Canon S820 pictures
The black pigment on both B/W and color prints from my Canaon S820 comes out speckled, for lack of a better word. Almost like a pointillism painting. This does not occur with the other pigments. I've tried a few different papers, both brand and type, but they don't really make much difference. It occur... 12 Dec 2005 16:21

Scanning from within a Visual Basic project
I tried looking in the archives, but I'm rather poor at searching, so I'll ask. The subject pretty much describes my question. I want to scan from within a VB project, and don't have any idea where to begin. Any and all help would be appriciated. -- David Froble Tel: 724-529-0450 Dav... 5 Dec 2005 14:37

About resolution in HP Scanjet 4890 / HP Scanjet 4850
I have had a HP Scanjet 4890 for a few weeks. It is a 4800 dpi scanner that I intend to use to scan film. But can't get a resolution that is anything near 4800 dpi. I have measured the true resolution by scanning a sharp edge and a special matlab program. You can find info about this program at: http://hem.bredba... 2 Oct 2005 07:15

A "slanted edge" analysis program
Well, my Imatest trial is up, and I'm not going to buy it (though it is a very nice program that I'd recommend!), but I'd still like to play with ESF, PSF, MTF and all that. Specifically, I'm still very interested in findout out what the "best sharpening" for my scanner is by analysing the edge spread function. ... 8 Oct 2005 22:24

Not there
Since 1999 I have had an HP ScanJet 5200 scanner on my computer, OS is Windows 98SE. The computer had to be completely reformatted due to a nasty trojan (we think). They were able to get back and save all the data and everything but my scanner seem to be working okay. I tried to add scanner in Add/Remove hardwa... 7 Sep 2005 19:39
