Epson v800 8x10 transparency vertical banding

I'm curious. If the 1-3% of banding occurs normally with this scanner, where else might we see this problem on normal shots?

Well, technically it affects every scan of every negative. It's not a good choice for, say, archival preservation of large format negatives.

However, it is rare that you will see the unevenness in a normal photo. The exceptions seem to be truly empty sky or perfect light-toned untextured backgrounds. I first noticed this in the sky of a landscape on an overcast day and I see it in the test shots I use to evaluate development evenness. The latter are photos of a blank white evenly-lit stretched canvas that is out-of-focus. So perhaps you could not scan Avedon style portraits well with these scanners.

Some other options are sourcing an older scanner (speculatively), medium format DSLR "scans" (maybe good for 100MP), and drum scanning services for $$$$.
