PhotoScape X is another free* program you might want to try. Lots of features and easy to learn, with plenty of video tutorials.

* - Its "trial" period has no end, so it is effectively free. There is also a paid Pro version, but the free version will probably meet all your needs.

Both Windows and Apple have simple photo editing programs built in. Try one of them to get the hang of it, then use Search in UHH and you will find lots of responses to similar questions. Many programs are free, and the ones that cost usually offer free trial periods. If you shoot RAW, you will have more flexibility in editing. Good luck!

Here's another try, tweaking mostly WB tint and temp and slightly reducing saturation in masked mountain and cloud areas. (Sorry, I clicked Store Original, but it did not download.)

Does adjusting the WB -- making the tint less magenta and cooling the balance slightly -- in a mask on the mountains have any effect?

Great shots -- thanks for posting.

If you get the Smithsonian channel on your TV, it has hour-long shows on Air Disasters that focus on the investigations of actual crashes. It's fascinating how they can ultimately pinpoint the problems that led to the crashes, a critical need in order to prevent future disasters.

Very nice set -- thanks for posting!

Great shots -- sharp, nice color, and interesting subjects. Thanks for posting.

Thanks -- will do. I'm a travel nut, currently confined to quarters, of course.

Great pics, and thanks for the fascinating narrative.

Welcome! As you have seen, you'll get lots of different opinions on this forum, and there are many good choices for PP software.

If you shoot Sony, Fuji or Nikon, I suggest the free Capture One Express. It is intuitive to learn, it has many great features, and there are lots of online tutorials and webinars. If you later want to add more sophisticated features, you can upgrade to the outstanding Capture One Pro for a one-time charge. C1 Pro has free updates during the year, and a major upgrade about once a year that you can decide whether or not to purchase. https://learn.captureone.com/webinars/capture-one-express/

If you shoot Olympus, I recommend PhotoScape X. The free version (called a "trial" but it has no time limit) has many features, and again you can upgrade for additional functions for a one-time charge if you want them. I've found the free version to meet all my needs for the TG-5. It is easy to learn, and there are online tutorials. http://x.photoscape.org/

Fascinating, and the interior and exterior seem to be in remarkably good shape -- thanks for posting.

Thanks for posting -- good information, and beautiful shots!

Very nice -- thanks for posting!
