Hello everyone,

Can anyone give a brief tutorial or link to one that has tips on how to scan oversize artwork on a normal sized 8.5 X 11 flatbed scanner?

I scan my pieces in 6 to 8 sections, but when I go into Adobe Photoshop to stitch the edges together or to overlap sections,  I am finding that each scan, scans with a slightly different lighting.   I make sure that I place the artwork on the scanner facing the same direction for each scan, I don't turn the piece around.  I have  made successful  pieced scanned images but it takes a ton of post work, that I feel is way overkill because of something I am doing wrong initially.

Any ideas on what I might be doing wrong to get the tone of the  images to be so different even though they are side by side scans within seconds of each other?

 

sincerely,  Qetesh

How big is the overall work? You may want to visit a place where you can use a larger scanning bed and simply scan all at once, reducing the size as needed.

Pieces will scan with slightly different looks depending upon the texture and color of the piece you're scanning. There's not much you can do to avoid subtle differences each time you scan, especially if the individual sections vary in light and dark.

The problem is probably that your scanner is set to do automatic exposure prescan each time you scan a section. Because each section has differing amounts of lights and darks, the autoexposure setting reads differently on each one and the result is varying exposures for each section. Depending upon the quality of your scanner, the software driver that comes with it may allow you to set the exposure manually, thereby permitting you to keep the same settings for each scan. Less expensive scanners may not have this feature.

For what it's worth, if you have a digital camera you may be able to do the same work with fewer shots, depending upon how many megapixels it captures. Again, you'll want to set the exposure and white balance manually so that they stay consistent for each section. If you'd like some tips on how to do it, let me know.
