BSA227, Green screen day! 31 August, 2016

Green screen work!
visual fx data sheet
the effect happening in that real world shot: animators records info with film crew
element data sheet should be filled in as fully as possible.
it makes matching footage later easier
camera info, motion description, dutch: tilt, lens type, measure height of camera etc. so everything can be matched up later.
then, in green screen room, you can match everything that's been done with the camera
clean plate important
so things can be masked out.
reflector ball is broken, so never mind.
light ball polystyrene ball on  a stick, put in front of camera fir referebce,
animators can make sphere in maya with white lambert and try to match lighting in maya with the ball in the live shot
time of day sun angle, weather, what lights used:
 draw a lighting map or where sun coming from
all these things help in post production
four pages to fill out!

for today:
try to match green screen shot with what's happening in live shot

I can hear Parth in the background trying to arrange a test shot with an actor walking across the screen.  Good thinking, Parth!

We tried out the green screen and I got some instruction on how to set up lights from Kate, Johanna and Nicola, then Vaughn showed us how to set up the black magic camera.  Parth filmed Kate in front of the screen.  Now to try to integrate the footage with the alleyway shot.
I will go back to the lesson on green screening the lady in the room/castle for how to do this
