	Re: Greenscreen Histogram by Tim Kolb on Oct 22, 2009 at 5:53:36 pm The idea with a green screen is the amount of difference to the foreground... 50 IRE or whatever number you pull out of a hat is best if whatever you're shooting is quite different from that... If you're shooting something very light, a darker green will be easier to preserve grayscale...if the foreground object is darker, a brighter background will be easiest to key out. Renting a waveform monitor would be the best because a horizontal histogram is difficult to use for this purpose.

	Re: Greenscreen Histogram by Craig Seeman on Oct 22, 2009 at 8:01:52 pm The poor person's method is with Zebras. I believe they have a ±5 unit range in the EX cameras so if you set them to a number (say 50%) if the entire green screen Zebras you'd be 45 - 55%. Using this is a decent "dirty" method of testing to see if you're lighting the screen evenly. Respond to this post   •   Return to posts index

	Re: Greenscreen Histogram by olof ekbergh on Oct 22, 2009 at 11:10:51 pm Well there is always the old light meter. I still have 2 Luma Pros. And they are great at checking how even light is and to check how many stops between highlight and shadow. Scopes of course are the best, but they weigh more than a Luma Pro on location.
