In the first cutscene with Fragile, there are hand prints in the cave. Once they come close to Sam, one of them forms some ice particles (?) on the floor, but I wonder what caused this? His breath?
Also the photograph that drops: was it on his clothes, or was it already there?

I assume you're talking about chiral crystals. In-game you see them form by destroying BTs, but presumably they get created by BT activity normally. And yes, he's carrying the photograph.
