The Hillary camp was accused of doctoring one of Obama's photos last week, a theory which was quickly shot down by the web's resident tech expert (since I was somewhat "unavailable" ;) ).
This latest scandal, courtesy the inimitable Frank J. of IMAO, is going to be much harder to disprove...
As a photography "expert" (heh, yeah, I do use the term loosely), I certify that it is 100% genuine.
Update: The plot thickens. Is the Obama campaign manipulating their own photos? You be the judge.
