Use a waveform monitor to measure the evenness of your lighting across the green screen.

This will help you in post production by narrowing down the shades of green your keying software will have to deal with.

What Lights Should I use?

For lighting the screen you will need a big soft light source. 

Using soft lights will help to reduce any imperfections in your screen.

I use fluorescent lights.

  • Have A Green Spike That Is Prefect For Lighting Green Screens
  • Are 5600k – Today’s Cmos sensors love daylight temperatures

Tungsten Lights will work too – but they need to be diffused.
