I have a Canon CanoScan LiDE210 (a USB flatbed scanner)
WIA is meant to be the new way to acquire images in Windows, as a replacement for TWAIN. Except when I use WIA I get this very limited, cut-down UI that doesn't present many options at all, just some Presets. The (somewhat hidden) custom settings screen only lets me adjust the DPI, output file type, and brightness/contrast. I can't see how I can get better control over the scanner and I have no way of knowing if it's going to perform any kind of processing of the image that I don't want.
Canon does offer TWAIN drivers, but on 64-bit operating systems it only offers 64-bit drivers, I cannot install 32-bit drivers - which is frustrating because Photoshop CC only supports TWAIN in 32-bit mode on 64-bit systems...
What's a scanner-guy to do? How can I get better control of the scanner via WIA?
Here's another frustration: the WIA UI only lets me scan up to 600dpi, even though the scanner has an optical resolution of 4800dpi.
