Classic pics!!
Only been to Amman for about 40 minutes when my Bahrain-to-London VC10 stopped there to refuel in early 1965, at the end of a military one-year tour (RAF Muharraq).
I use the GIMP plug-in G'MIC-Qt. Amongst many, many edit functions it has:
Artistic>Stylize - based on the works of well-known artists such as Monet.
Here's an original, then style of Monet's 'Lily Pond' with just one click ...
I sympathize. Had a similar neck operation three or four years ago. My left hand has chronic shaking but at least the right hand can still work the mouse so far.

Top left is Contrast-Limited Adaptive Histogram Equalization ## with default setting
Top right is Equalization in the GIMP.
Bottom left is same as Top right...
Wow!

In image 8 (primary, secondary and tertiary? colors) it is quite surprising how bad "CIE Y" is, compared to most of the others.
One such is RawTherapee which has an option to apply RL deconvolution or USM, post-resize - in addition to any applied in another tab.
Others, Like FastStone Viewer or the GIMP, allow sharpening several times during editing including both before and after re-sizing.
There is an issue with Uploading Photos (attachjments). I am not sure what the problem is, and I am looking into it. You can still try to Create your Threads and Upload your Photos, but it is hanging up during the Upload.
