CHROMA SHOOT  (BLUE/GREEN SCREEN):

1)  for dv shoot on green screen as the video signal is compressed and some  color information is lost. 

2) avoid clothing matching the color of chroma screen.

3) light screen from front.

4) there should be no shadows on screen.

5)use gels to neutralize the color spill on foreground objects backlight.

6)keep at least 12 feet distance between fg ( foreground ) and screen.

7) use no special filters while shooting.

8)check the uniformity of lighting with a spot meter.

9)avoid shiny objects with glossy surface or shiny surface .

10) never use dimmers with lighting the screen as it lowers the color temperature, making the blue more orange.
11) capture with better sampling ratios . 4:2;2.

12)check what stock the dop is shooting on.

13)the dop should not use fog, difussion,superfrost or smoke when shooting chroma.

14)light your screen for its hue and not just to make it bright.

15) there should be no reflection of the screen on fg object or talent.

16) use a flat lighting scheme as far as possible.

 17) dop should not use fog, difussion, superfrost or smoke when shooting chroma.

18) colorist should not sharpen /denoise/deblur/use filters/or adjust the screen color....that part is more difficult to control than the DOP.

19) Motion blur kills the best chroma screens. Using higher speeds on the cam often does a pretty good job.... but wants a "little" more light or simply adjust the shutter angle, but then u have to avoid panning movements.
