Brent, I've used a salad of photo editing and illustration software over the years as part of our business illustrations and presentations. GIMP is a product of the "Open Source" community that believes that quality software should be made available to the public. GIMP of course stands for Graphic Image Manipulation Program.
It is extremely powerful and it following is worldwide and there is a wealth of training available on YouTube and other sources. I doubt that one could go wrong for a zero cost investment and for editing images it does all anyone would want it to.

No. Sippyjug, not to single you out as many others in this thread have made similar claims about GIMP. Your post is just the most recent and someone needs to say no to this misinformation about GIMP. No it can't do all anyone would want.
It can't do what I want and all I want to do is simple stuff like darken a sky -- efficiently. Yes GIMP can do it but not efficiently. GIMP is way too expensive because it's so inefficient. Here's an example. I attached a photo below. It's a straight raw conversion with no additional editing. First job is to darken the sky.
I don't want to just drag a gradient over it because of the tree branches. I want to darken and saturate the sky with little to minor effect on the tree branches and I want to keep the the tops on the trees on the left side looking natural. I also just for reference attached my processed version of the photo so you can see what I want in the sky.
Can GIMP do it? Yes it can, but can it do it easily and efficiently?
An emphatic NO! I recorded the steps it takes to just darken the sky using three different apps. Here they are:
Capture Oneone mouse click add layer.
one mouse click type value set exp reduction.
one mouse click type value raise saturation.
one mouse click activate luminosity Range.
two mouse clicks adjust luminosity range limits slider.
one mouse click turn off display mask.
two mouse clicks adjust radius & sensitivity sliders
one mouse click OK.
one mouse click activate mask eraser and remove unwanted mask in water and grass -- done.
Photoshopone mouse click duplicate layer.
one mouse click set blend layer to Multiply.
one mouse click turn off dupe layer.
one mouse click select magic wand.
4 mouse clicks to select the sky.
one mouse click turn back on dupe layer.
one mouse click add layer mask which conforms to selection.
one mouse click to bring up Refine Mask dialog.
4 mouse clicks with slider adjustments to set refine mask parameters.
one mouse click OK.
one mouse click layers palette adjust dupe layer opacity -- done.

one mouse click Colors menu.
one mouse click Desaturate dialog.
one mouse click set parameter to Luminance
one mouse click OK.
one mouse click go to Channels.
one mouse click and drag Green channel to duplicate channel box.
one mouse click back to Layers.

done.
Notice how much more involved the process is in GIMP. While someone -- assume a GIMP guru is stepping through that I'm finishing the rest of the edit in C1 and I'll be on to another image while the GIMP use is applying another excessively involved and convoluted sequence of steps to try and finish this edit. With serious work to do I get the weekend off and the GIMP guru burns the midnight oil all seven nights of the week.
GIMP in theory could do the job the same way I did it in PS (Affinity can -- if not better) except it can't because it lacks that Refine Mask Edge option in PS (and Affinity) and because in PS you can see what you're doing but in GIMP trying to refine a selection edge is really irritating because you can't get a good look at what you're doing till you do it and then go oops and undo and then redo it and go oops and undo it and then redo it and go oops and then undo it and redo it and then settle because you can't stand it any more. Reading that last sentence is often what it feels like to work in GIMP. Yes GIMP can do it but you don't get the weekend off.
