@tomnorthfilm @carusb @nanoelquant yes, you're right, I should've clarified which files! I'm building a film inversion tool, so I'm trying to estimate the amount of resources needed to process an average file.

@analog_cafe @tomnorthfilm @nanoelquant If I wanted to do a film conversion from a negative scanned at 3600 samples per inch (one of the native resolutions of my Plustek 7500i... 1800 spi is not fine enough), I end up with a 100 MB 16-bit TIFF or DNG Vuescan RAW file. I'd guess the Silverfast AI RAW scans would be similar. So 3600x3600x1.5 =? 19 Mpixels x3 colours x2 bytes ~ 116 MB...
