I'm putting together a team to work on restoring these scans.
I need at the very minimum:
1. A colorist
2. Two dirt cleaners
3. An artist to fix really bad (e.g., big scratches) damage, just in case
4. A QA person with deep knowledge about the film
Volunteering will obviously get you early access to the scans, but you must have the skills, free time, and equipment necessary to do the work.
I plan on wearing a few different hats. Send me a PM if you're interested.
