As a random Linux schmuck user who occasionally does very light image editing and processing, the few times I've tried to use Krita I have absolutely no idea how to do anything (without looking up a guide), while I can usually do whatever in Gimp pretty easily. Granted, I've never tried for very long, but that was my first impression.

Maybe Gimp has just rotted my brain over the years with its UI...

Are you familiar with Photoshop etc workflows? Krita is pretty similar to those, whereas Gimp is the outlier in UI/UX.

So I can see going from Gimp to a more standard interface being difficult, if Gimp is what you're used to. Conversely so many people hate using Gimp because of the same reason if they're used to Photoshop

Oh, absolutely, hence why I joked that Gimp has poisoned my mind. I'm not sure which would necessarily be more intuitive for a total beginner, but I know I'm just used to Gimp.

On top of that, I downloaded Krita again, and the UI seems more approachable than I remember. Don't know what's up with that, maybe there was some freak misconfiguration last time I tried. Ah well.

Sounds like you opened Krita expecting it to behave just like Gimp. You should take an hour and actually learn Krita. As someone who learned photoshop in the 90s, InkScape, Painter, Gimp, etc. Krita is my GOTO for any art needs now.

I tried to load 30GB image to Krita, it crashes. Gimp handles it pretty well.

Hmmmm, how much ram did the PC have that his happened on?

Did you mean MB rather than GB?

Kind of wondering what kind of image would be 30GB... :)

Thanks. Found info on that file format:

Pages 14 onward give the info. Seems like it's a variation of TIFF, in tiled format.

Main tile (image) size is 120k x 80k. That's huge!

29GB when saved uncompressed. I'd hope most applications would use the optional compression features. :)

This was 360 degree mosaic, about 100kX100k
