GREEN SCREEN SETUP

The green screen setup is very quick and easy. There are 4 collapsible “tent like” aluminum poles. The poles themselves are nice and sturdy. They are 5/8″ aluminum which was larger diameter then I thought when looking at the photos in Amazon. The 4 poles connect into 4 milled holes into the center frame piece (the green circle). The ends of the poles go into 4 grommets on the corners of the screen. That is all for the setup.

One thing that I was really curious about was how would it stand. The design actually worked much better than I had thought. By design, the holes in the center piece are milled at an angle. The X-frame angles back away from the screen. The serves 2 purposes. First, this offsets the frame away from the screen to prevent the screen from creasing over the frame. Second, this allows the weight of the frame and the center piece to be behind the screen so the weight naturally goes back. This allows the center piece to rest against the wall with the screen nearly vertical. Once against the wall, the weight stays back against the wall very well without worry of it tipping over. The screen itself is about 11″ offset from the wall.

Once setup, the screen remains tight and wrinkle free. I left it up in the same location for more than 2 weeks. There was no additional sagging, folding, or wrinkles during during that time. The design itself is 7′ 10″ x 7′ 10″ which allows it to fit under an 8′ ceiling.

IMPORTANT SET UP NOTE: If you are like me and choose to not read instructions, there is a 50% chance that you will set it up incorrectly the first time (which I did). As mentioned, the holes in the center frame piece are milled at an angle to keep the frame angled back away from the screen. If you set it up with the center piece turned around backwards then the frame will angle into the screen and cause it to bulge outwards. It is pretty obvious when you’ve done that. If that happens then just turn the center piece around and  it will be fine. See the image from behind the screen. This is what it should look like when assemble and leaning on the wall. Remember, you really don’t need to angle the screen back itself. The screen can be vertical or nearly vertical as the frame itself “leans” back.

GREEN SCREEN COLOR

By Far, the most important aspect of a green screen is the actual color of the screen itself. I spoke directly with the manufacturer of this screen. The screen is color matched to Pantone 354C. During the manufacturing process, they maintain a tight quality control tolerance with that color. Pantone 354C is a standard PMS color match for green screen.

I tested the color from the initial setup image of the screen itself. I made sure the raw image was properly white balanced in Adobe Camera Raw. I then opened the raw image in both sRGB and Adobe RGB 1998. Also, for the raw conversion, white balance was the only adjustment made. The camera Profile was set to “Camera Neutral” to avoid and artificial color saturation. EZ green Screen 5 was then ran on each image and the color was checked using the “Screen Color Check” feature which displays the average color of the extracted part of the image.

The color samples are shown on the right. For RGB, mathematical pure green is hue = 120. For this screen, the sRGB hue was 132 and Abobe RGB 1998 hue was 101. This is about perfect for a green screen. The reason for the different hues is because sRGB and Adobe RGB 1998 use different red, gren and blue channel values to represent the same exact color. For true chroma green screen, the hue is typically a little above 120 in sRGB and below 120 in Adobe RGB 1998. For the green color spectrum, the more color saturation there is, the more of a hue difference there will be between the 2 color profiles to represent the same color. The color of this screen is ideal because it works well in both sRGB and Adobe RGB 1998.

TEST EXTRACTIONS

I did a few test extractions. There were no major extraction issues seen. Since this screen was a pretty highly saturated green color and the dimension was fairly wide at 7′ 10″, I did the test at 4 feet from the screen to try to see if I could induce some spill in a “worst case” setting.  For the image of my boy, there was just a very small hint of spill on the right side of the face next to the eye, almost too small to really notice. However, the EZ green Screen spill correction had no issues fixing the color. Other than that, everything was spill free. At 6 feet or greater from the screen, there would for sure not have been anything at all.
