darktable -vs- GIMP

Hi Claes,

I have a Canon EOS Rebel DSLR. It’s set to its factory default
settings as I don’t know enough re: cameras to know what alternative
settings I should consider and why set them to those settings.

I’m on a wild journey to learn re: photography and graphics!

I started by learning a few tasks in Gimp - e.g. add arrows, text,
Perspective Tool, etc.

Thanks for your insights.
