After finishing the second Rob close up shot I went back to the opening wide shot to see if I could make it better.
Sure enough, after using Primatte and a Mocha Pro travelling matte; along with the usual KeyChew node and a few hold out mattes it is now much better. So much so I can feel confident to move the footage up so you can see the feet!
Graded again using Saphire Glow.
Then tackled the one shot which caused me all the heartache - Alex close up.
Took longer but with a stagically placed Mocha Pro travelling matte on her hair it now works. Pleased.
Onwards to the next mid shot!
