Well, the photographer in question has a very narrow view of omission and addition. He suggests he does neither, but indeed he does add something quite significant: time. And in doing so creates something that wasn't. All photography is deceptive, partial, and false in some way, but this is purposefully so. His "challenge" of HCB's decisive moment is a silly premise that photographic talent with Photoshop skills. It may be some sort of art, but it's hardly straight photography.
