If you're a photographer - or just a viewer - you'll know that the ability of someone to "Photoshop" an image to have it display something different from what was visible through the camera lens has come a long way. So far, in fact, that most of us realize that the "photographic record" is probably an oxymoron.
Of course, that isn't necessarily a bad thing. You can do wonderful things with your photos by manipulating them. What you end up with in a photograph is often not what you were seeing - at least not the scene that you remember. Playing with the light and shadows, colours, etc. can often recreate something closer to what you were hoping to capture.
If you're the type that likes that sort of thing, prepare yourself for the next "really cool" step. Photoshop is readying a new tool called Content Aware that brings the ability to fine tune images to a whole new level. To see what I mean, watch this video on YouTube.
(Note that I haven't verified whether this is really a post from the Photoshop team. It might be someone's idea of a prank. But it does look convincing.)
