Chroma-key and isolating subjects.

[Justinr]

I have just started using a light tent and am bothered by the presence of the background that often still shows as a faint blue/grey rather than pure white. This is especially noticeable when using a polariser to cut down on unwanted reflections. I'm told that the Chroma key/blue or green screen method is one way of overcoming this although I am not sure as to how I set about doing it. Anybody else use this method?

We use it in the studio, the background needs to be well lit, then we simply use select colour range, tweek the fuzzeness slider and job done, it helps if your model ISN'T in the same colour as the background (unlike our first test model LOL) I noticed but the photographer testing the kit didn't.  (and needless to say I didn't tell him till he'd finished)  Wayne
