@analog_cafe @nanoelquant I answered 100 MB specifically for Vuescan Raw scans in 16-bit TIFF or DNG. I only use RAW for slide film or conversion experiments. Most scans (99.9%) are straight to JPEG, around 5 MB.
@analog_cafe @nanoelquant I'm worried that the ambiguity in your question, indicated by your reply "TIFF or PNG" will taint the reliability of your results!
@carusb @nanoelquant yeah it'll be approximate, that's for sure! I'm generally interested in how large those files get for most people (thus, the largest file in the process). I'm building a film conversion tool and trying to size the resources.
