It's all semantics at the end of the day, everyone doing this stuff has different aims and different parameters. I haven't seen a screening yet where I can't see the mattes, so I am personally leaving them in on the work I am doing. For a version that I want to sit down and watch and enjoy, they are being corrected out. On another film I am working on the wires holding a model are just barely visible, I could correct them out just with colour controls, but I decided to leave them in. It really does come down to personal preference. We have no client, so can do whatever pleases us for once in our lives!

[For my own enjoyment I am making a version that is how I 'remember' the films, (i.e. better than they look on the prints) with many of the shitty comps, mattes and glitches removed, but that is a different project altogether]

Just out of interest, where the mattes sit over the top of lighter items and are still visible, are you correcting those out as well?

I've done it both ways, just wondering which way you are going with those?
