Wired is running an article discussing how computer scientists are developing software that attempts to detect when a photograph has been altered. The article

discusses legal ramifications of such software — particularly with regard to criminal defense matters. It appears that the software would not distinguish between arguably permissible alterations (e.g., lightening a scene) and impermissible falsifications (e.g., cloning away evidence). As these tools become more widely available and affordable (one set of tools costs $25,000/year), they may constitute another arrow in the wise litigator’s quiver.
