I agree, pretty sure the host upload is at fault here.

A simple LED strip light, you know those flexible ones. They were glued on the inside (just the bottom panel) of an aluminium box 30x40x8cm and then a frosted acrylic panel was placed on top. While the light color is not that important I chose a neutral white. But I reference each scan images white balance from a reference image of the light table so it gets compensated anyway. Worked like a charm when I still shot analog. Gone digital now unfortunately as the costs just rose too quickly as a college student. Still miss my Fuji GX680 sometimes, but I'm also really happy with my Fuji X-Pro 2.

Time to blow dust from my Autopano Pro license! (Yes, it still works on macOS 15.1 on Apple Silicon).
