looks totally real to me. I like how even the long dead tree thats fallen in the water with no leaves is red.

What you're seeing is a combination of color bleeding due to aggressive color noise reduction and a hue shift due to how the color saturation was exaggerated. In the raw image data you get a lot of colored speckling called chroma noise and the more you do to reduce this the more colors from adjacent objects will bleed into each other. This is especially apparent when dealing with tightly packed relatively colorful objects like foliage. Red hues from leaves from one tree will bleed into the bark of an adjacent tree or the water near the trees. The other issue is that when you see a bare tree that is "brown" it's not represented simply as brown in the data, but as a superposition of the color channels. When you exaggerate the oranges and reds in order to makes to leaves look better, you'll also distort other colors like browns and if you have areas that were already pretty intense they can end up getting blown out in one of the color channels. The sample you provided there certainly looks like it was done by someone in the "HDR hole" stage of photo post-processing but there's no signs of actual manipulation other than going nuts with saturation sliders.

Actually, the post-processing tool he used is called a paintbrush. It’s used to apply colors on top of the image that aren’t naturally present. You can tell by looking at the lazy paintbrush strokes he used, like on the red tree in the water and on the bigger green patch at the bottom center of the frame - funny how only the top half of that green tree has a stroke of orange color and the bottom half doesn’t yet the whole tree is surrounded by orange leaves. I guess you’ll agree this is not the artifact of color bleeding or blown out colors.

This thread is freaking hilarious. So many people who clearly have no clue what they're talking about being so damned confident. It's absolutely shitty post-processing, like I said it's reminiscent of the "HDR-hole", but there's nowhere the guy painted in color. If you had any experience with photo post-processing it would be painfully obvious what actually happened but please continue basking in your ignorance.
