lol they're all Photoshopped as hell.
In the first one with the sunset, you can see where the sky meets the dark landscape and there's a weird black glow that bleeds out from the ground. That's what happens when you blur an image and blend it back onto itself, perhaps if one was trying to get a 'bloom' effect in Photoshop.
