It’s really hard to claim “photoshopping” since its a huge part of photography. It’s called post processing. There are almost no pics that are taken by a professional photographer that are not edited in photoshop before they are uploaded/printed or what have you. Colors, sharpening, noise and a lot of other aspects are tweaked/corrected.
The first pic was indeed edited in photoshop, you can see it in the exif data of the picture. It was also shot with a Nikon D300 @ 24mm.
