Is that a day dream, or have you actually tried this enlarger/onionskin
approach? I know using a scanner for 2D-ish 3D objects works great,
but scanning a projected image? When a transparency-adapted scanner
scans, doesn't it turn off the internal light and rely on the
transmissive light? Wouldn't you want to do the same with the
projected image?
