Hmmm. Still got one of those in the attic. And the ancient Mac that came with it. System 8 and SCSI. Oh joy. ;) René Damkot www.damkot.com www.getcolormanaged.com Verzonden vanaf mobiel

A scanning back using a tri-linear array sensor, e.g a Betterlight scan back, would yield the same result in a single pass.

I'd guess you wouldn't get de-mosaic artifacts if you used something like a three shot DB? I'd think there are still modern variants of that around?
Although that might present other issues...

And that's all assuming you're limiting yourself to the Canon 5DIII. If you're doing oversized high-resolution art reproduction for commercial work, you're going to be using much higher resolution gear, and at least in medium format. There're many off-the-shelf offerings of at least 80 megapickles, and your budget is the only limit past that.
See my previous post for the *requirements*.
I’ll add that I think that high resolution capture using medium format is also seriously deficient because of moiré issues.
An example that comes to mind is photographing bird feathers. If you stick them in front of a studio back that can capture <250MB RGB files and take close up shots, take a detailed look at the individual barbs. I’ve found the weirdest artefacts generated by the cameras — bands of in- and out-of-focus image (in a sharp shot) or patterning like tiny little swastikas instead of real detail.
Stick them on the Lanovia’s scanner bed and you get exactly what you’re expecting — sharp detail without moiré issues.
Artwork for me includes stuff like etchings, engravings, woodcut and linocut etc. 300 dpi capture and funky anti-moiré issues aren’t good enough.
