Almost none believe it or not!
I ran a mild unsharp mask over them as I figured it couldnt hurt, and it didnt make any difference tbh, usually I end up oversharpening things to make up for a soft lens or similar.
As it was raw I opened them in camera raw and used the auto values, and again it barely changed anything, might have just notched up the exposure by .2 or something, and I changed the blacks value from whatever they were (~2-3) to 5 or something else non-major.
The only other thing was in the river shot there was a plank of wood at the end that was just visible once you really started to scrutinise the shot, so I clone-tooled it out. I cropped about 3% from the bottom of the river shot too, other than that theyre both full frame.
I also rotated it 180 degrees at one point out of curiosity. Seriously, looking at it upside down is weird, you kind of know its upside down but still end up looking for the waters edge in the wrong place.
