My chroma key with Vmix is generally always perfect. However, I have been running into a problem with white or pink shirts... that my shoulders are always too bright. I use smooth high quality LED lighting... so its not like I have spot lights on me. The rest of the key is fine. But for some reason it does not like those colors. Any setting I could adjust? If I adjust the brightness of the camera it causes issues from skin tone to just looking too dark in general. Any ideas or advice would be greatly appreciated.
