Hi, I set up a green screen and with markers on it that are a slightly lighter green than the majority of the green screen. I'm doing this so that another program (Labview) can track/measure the motion of the camera via the motion of the lighter green markers.
My question is what is the best way to chroma key out both of these shades of green? I tried putting two chroma keyers in the filter chain, but after going through the first chroma key filter, say for the majority green shade, the other green shade, the markers in this case, loose a lot of color, making it potentially closer to object colors in the foreground and hence the second chroma keyer struggles.
There must be a better way to do this.
