I use GIMP, and have learned a lot, especially about histograms and not only what they mean, but what can be done using them.
With the upgrade to version 3, one feature I miss terribly is the ability to open bayered pictures. It had been that when opening FiTS files, the choice was to check NAXIS=3, which I never did learn the meaning of. But now I have looked high and low, including the documentation, for the same functionality.
Has anyone found where it was moved to?

I could not get FITs to work properly, either. I submitted a bug report to GIMP. I just now checked and current status is a "plug-in issue". I tried reloading Darktable (the plug-in used successfully with previous GIMP for FITS) but no joy. So I guess I'm waiting on Darktable to update for new GIMP. I reloaded old GIMP in the meantime.
