incl. Pin cushion & barrel distortion visual demonstrations
3 hours, I'm watching it again but haven't seen the whole thing yet. This is a good one to listen to, to get familiar if you're on a drive or something, it's just audio:

This is Costella's introduction, great primer if you can sit down and go through it point by point, & it's not long at all:

Other symposium vids are coming, I just need to do one more and then I'll finally catch up on the playlists. I think I got this one from Palamara but not sure, but I downloaded it whole. Could be better resolution just don't stare too hard in the beginning when he's describing the ghost images and between sprockets, he details it zoomed in later.
