Thanks, LWW. I have to sit on my hands not to post the original pictures vs my finished product. The pictures I like best are ones that start out bland, and I fix them up so they look great. The opposite of "unethical", I'm more proud of a successful editing session than I am of most original, SOOC pictures. Actually, my favorites are ones that pretty much suck, and I manage to turn them into something I really like. Often, I am surprised at how good a "bad" picture can become. Hoggers often say you can't make a bad picture good, but I guess that depends on what you consider "bad". If you have a good subject, but the rest of the pic sucks, you often can turn a sow's ear into a silk purse.
To me, showing how great a job you did is more braggadocio and trying to pretend your skill and hard work is SOOC would be rather stupid, other than in a contest or something. People that don't know how to edit think everyone is trying to pretend their pics are SOOC, when it's about the opposite, we are proud of our work, both in and out of the camera.
Anyone skilled in editing photo's knows it is not so easy to successfully edit a picture. The more you do to it, the more likely it will have multiple problems. Overdoing edits is a constant problem for all, particularly beginners. Sky replacements are pretty simple on the surface, but, as many pointed out, getting the right sky and lighting right and so on is the hard part. Myself, after maybe 25 years of editing, I still miss the mark quite often, and need someone else to point out the errors of my ways. Lots of times I just give up and toss the photo into a digital drawer, possibly never to be seen again.
This picture started out as a cell phone "portrait", something I complain about to my daughter often as cell phones normally are better done in landscape, because they fit monitors and TV's correctly with minimum editing. I like my pictures to display nice on my HD TV which is 1920x1080. This image started out as a portrait mode image, 3034x4032, not ideal for HD screen display. To correct it, you need to change the canvas size, and then put something in the added space is a nice touch.
This picture started out in my daughters kitchen, so the background was not sky at all. Pretty tough to add kitchen background to the added blank space of the landscape mode pic. Initially, I started with just a black background, and it looked good. Then, I saw a milky way pic on the hog, and thought, hey, that would look good as a background for this picture, so I grabbed it. I could have used it, but is was not all that good of a pic, so I went to UNSPLASH, on Affinities Stock panel, and searched for MilkyWay. I rarely do this, because it's much more fun using my own pics. Anyway, I really liked the outcome, so I kept it.
