And why on earth would he, as an insurance investigator, have experience with DESTROYING Polaroids?

Him training himself simply means that through repetition he has become able to remember something. So if that's what you mean yes he can make new memories, but they are just habitual memories.

I don't know about the polaroids, he could have had experience for all we know.
