Either way, not getting far with that photograph, nowhere near the wiki photo.
Maybe.
Colours -> Auto -> Stretch Contrast HSV then Colours -> Curves pull the colour up to try and bring out the clouds.

There will be other/better ways
Hi Rich,
Thanks for replying - just to clarify, I obviously don't expect it to be anything close to the wiki photo, just needed those 3 columns to stand out a bit more. And I tried your techqniue of stretching HSV and then playing with colour curves and levels and that alone has made a huge difference! I'm quite happy with that now - thanks very much!
If others have other ways to achieve something similar, please post below. It's really cool to learn this stuff.
edit: By the way, I do have a Windows machine with GIMP as well. What does the gmic plugin do and how will it help here?
