How does Time Machine work for a photographer?

I am a photographer and I use photos that are about 15Mb each. I take hundreds of these per month and edit, let's say, about 500 per month. And sometimes I'll go back a week later and tweak a batch some more. Could someone explain, in detail, how the back-up process works? I'd like to be able to figure out how large of a back up drive I should get. Is it backing up/creating a new image file after every tweak of every knob I make in Lightroom? Actually, somewhat related, is this how Lightroom works? It comes with a "history" feature and I wonder how it is I can revert a photo on Lightroom if it was to not create a copy over and over while I'm editing.
