There are a total of 16 Filming Canisters in the game. If you hit it will show your progress while you are playing. From the main menu, you can also view the Concept Art that is unlocked. Each canister unlocks a different art piece. You will get the achievement after finding all 16. The best route to go about this is when you have found 4 grubs and find an upgrade station, go ahead and spend them on the upgrade that allows you to see them all on your map. This will make it a whole lot easier.

Note: As you gain powers, you'll be able to reach certain collectibles that you couldn't get beforehand. You will be backtracking. You really should collect everything that you can while you are there. There is a chance that the Laboratory has highly missable collectibles. You must get each one before you continue on. Make a backup save at the start on another memory device if you want a safer route just in case.
