I read the petapixel article, and it seems that AD Coleman writes an enormous buildup about how he's going to deflate Robert Capa and the myth of the melted negatives, and the end result is that he discovers:
- Robert Capa was actually on the beach at D-Day, actually took pictures of soldiers, landed a little later than the myth says, and mis-identified the type of a tank.
- The negatives were messed up in camera and not in processing.
The one who is inflating a myth here is AD Coleman. There's a phrase "the fog of war." I have never been in combat, but pretty much everyone who ever has, says that it's chaotic and at the time nobody knows WTF is going on.
