True, but I kind of prefer that personally and for the majority of them you have to figure out how to get access to them first and there are different ways of getting them (about 4 or so ways iirc which involves pretty much gliding, using explosive gel and batarang, using the electric shock gadget/gun, freeze grenade and bat claw and the remote batarang etc.)
What exactly do you mean by the camera puzzles?
The ones where you have to find the giant question mark painted on a wall (weren't too many in this game and some are pretty big/noticeable as well)
Or/and:
The riddles? Where you have one like "where all the madness began" "the root of all evil for poison ivys plants" (or something like that) and you have to hold "x" to solve the riddle. There are loads in this game, just have to find riddlers informants and interrogate them to get all the stuff to show up on the map.
