[QUOTE="Horoscope Fish, post: 151929, member: 13090"] If you mean an iron-clad, 100% effective method for determining what/how/if a particular image was Photoshopped, there isn't one. At least not that I'm aware of. You can perform tests like Error Level Analysis but I don't think that's going to spot more subtle manipulations. Not that I'm any expert but two give away signs I see a lot in less-than-ideal Photoshop jobs are tool-marks like repeated patterns (bad clone stamping) and incongruent light and shadow. I'm sure law enforcement people with real training have other far more sophisticated tools but I don't know what those are. [COLOR=#ffffff].[/COLOR] [/QUOTE]
