A really quick way to bake this kind of info into your brain... is stick a polaroid back on and grab a notepad. There's something about taking a shot, examining it, coming up with what seems the correct next step, and trying it out instantly... vs. shooting a roll and processing and trying to suss out notes for every frame. In the pre-digital days it was a dynamite way to learn some more advanced stuff very quickly or test your crazier ideas.

There's still 2 decent flavors of pack film available after all... and peeling those things always brings back memories (for me anyway).

EDIT: you can likely get a hassy polaroid back for next to nothing thee days, if you don't have one...
