I know, this is 'lame', but it's still proof that she uses photoshop. I took all of her own posts from a set amount of days and found the original photos. You can see the difference in them as well as screen shots of the two posts' properties.

And there you have it. She uses Photoshop to change and enhance the photos to her liking. It makes no sense, either, because the original photos are just fine.

I am also sorry if the formatting is weird, or off. I couldn't get the photos to match up the way I wanted them to so I used pre-formatted text and previewed it a billion times to make sure it worked.
