I purchased a 5x7 collapsible chromakey green backdrop and am having the hardest time with it. Come to find out that it is not a true chromakey green (from other articles I have read). The software I am using does not recognize it much because of the color. Green Wizard Pro support told me the RGB values their software recognizes and I go into replace color and put in the values and that messes things up even more for their software. So I use the color values from a muslin green screen I have (from previous shoots) but the green looks nothing like the image I took the values from. Why is it when I put in the RGB values of one screen color into another they look nothing alike but all have the same values. I am thinking of selling it because I cannot get anything to work right. So what should the RGB values be of a true chromakey green background and when I buy a collapsible one how am I to know it is a true color that will work. The other softare I am using is the easygreenscreenn plugin and the author said it is not a true green for his software to work with.
