I question becomes, does that matter? If everything needs to go through forensic experts, that works for courts. For media, who knows. Maybe it just becomes another way to challenge anything.
There's always been a certain value to letting people see things themselves, and use their non-expert judgement directly, en masse. Think of that iconic image of a Vietnamese girl escaping napalm or (more recently) the drowned refugee child on that Turkish beach. These had value past the factual information.
In any case, I think the Photoshop/stills case is a little heartening. We get an occasional false image, but overall it hasn't created some sort of massive truth-crisis. Other stuff did happen to truth, but Photoshop wasn't at the centre of it.
