help?

Does anyone know how to prove if a picture has been Photoshopped? Like, is there some way to open it in Photoshop and take it apart?

All Photos manipulated in Photoshop are watermarked with "Photoshop " in the extended attributes of the file. This is done automatically and I don't know of a way to stop it, so If you get a image viewer that will display the extended attributes of an image file, you should be able to tell.

Only if they are sloppy. Visit the Fake Detective for a primer on faking and detection. It's geared towards porn though...

Pixel inspection (at ultra high zoom levels) around the areas assumed to be pasted in (like heads) is usually the best bet.

Wait. So you're saying that's NOT really you and Nomar Garciaparra in that picture???

The fact that is was opened and saved from Photoshop does not mean it was "Photoshoped", in terms of creating a fake. All pictures start as something format and get saved as a gif of jpeg for the web.

Of course if you have the .PSD file you can see all the layers. When a Photoshop file is saved to the GIF or JPEG format the layers are merged.

I couldn't "prove" it, but I can generally tell if an image has been manipulated in some way.

not sure what image this is related too, but you could always post it on a forum like CGTalk.com and ask them if they think it was photoshopped. I swear that some of those guys could look at a real photograph and point out the one pixel that was modified.
'course, it's dangerous ground though. Lotta liberals over there.

Can you please explain exactly how I can check for this watermark?
