You should go watch this program 'honour and valour' (i think) on discovery channel. Caught it a few days back..really great..shows reenacments of how Capa got some of his shots during d-day. I believe on a military transport ship was where his famous 'if your picture is not good enough, you're not close enough' line came from.
In the documentary, he was depicted as having a conversation with two other photographers/filmographers in a military transport ship on its way to France (however, this was the false start of d-day, where the invasion was delayed due to bad weather).
In this conversation, one photographer raised that it was safer to stick with the E Company, as they were behind the first wave of infantry to land on the beach. He also raised that C Company was dangerous as they were part of the first wave of infantry.
However, Capa went and asked, 'Where's the action?'.
The other photographer replied, 'The action's everywhere'.
Capa then said, 'well, if your picture is not good enough, you're not close enough'.
Well, that's roughly what i can remember from the docmentary, some parts may be wrong but mostly correct. I think he was wearing the same battle fatigues as the infantry men, but I wasn't really paying attention... =p good luck in finding what he wore and the model...=)
