How you edit REAL monochrome images? (from Leica)

I bought a cheap monochrome camera for the Raspberry Pi to use in a spectrometer. Turns out it has an IR cutoff filter, so all light above 660nm is lost. I may yet scrape off the IR filter, but I’ll probably buy a proper spectrometer instead. It is interesting to regard its images: surprising resolution for a 640x480 sensor, and what looks like at least two stops of increased sensitivity.

There is also a no-IR filter version: Buy a Raspberry Pi Camera Module 2 NoIR – Raspberry Pi

I have the V1, but sadly never had the time to use it for anything meaningful.
