I find it strange that more people have not brought up the 'lost-sale' fallacy. By saying 'no' he actually loses out in the end because if the magazine is only looking for free photos, say to the keep costs down, it will just go elsewhere and the readership of that magazine will probably never know about that amazing photograph nor the photographer himself.

That argument is only bullet-proof when all magazines are in exactly that position. But some magazines may well just want to use that picture and try to press the cost of using it.
