I have a question about the usage of the pattern "identification in" pattern here:
Three Marines depicted in the photograph, Harlon Block, Franklin Sousley, and Michael Strank, were killed in action over the next few days. The three surviving flag-raisers were Marines Rene Gagnon, Ira Hayes, and Navy Corpsman John Bradley. The latter three became celebrities after their identifications in the photograph.
The act of identifying the flag-raisers was external to the photo and after the photo was taken. So, is the "in" in the part "identifications in the photograph" wrong? Would "identifications from the photograph", where "from" implies the source of information, be better?
