I wasn't able to figure out what to do with the 0209 and 0210 values.
Those are not values, just the names of those two images.
I'm also guessing that this will all be camera specific
Indeed. I think I lessened correction indirectly by faking tele zoom at a few parts of Canon's image processing code. It happened a long time ago, so I don't remember all details. It's possible there are better ways.
