I read a thread here about this subject in March. I used black screen on some transparent jellyfish puppets. They look fantastic...until I use the luma filter -key out darker (as suggested in March thread). After using the filter, they look muddy against my watery background. Any tips?
You should have used a Blue or Green screen. Black with transparent...not all that good. Whoever gave that advice gave poor advice. For proper keying, you need to use GREEN or BLUE...and not any green or blue, but proper keyable green or blue.
