Seems counter intuitive that if I add more light in the foreground that I'll actually reduce the reflection. I select using that method, modify the extraction and contract a pixel or two and I almost always get a clean extraction. I had limited lights so I couldn't get the backdrop as uniform as I should have, but Select->Color Range is working nicely for extraction. The dark areas are exactly where I see the reflection. These are the areas that leave residual green on a still photo subject. Dark areas are where green screen (Chroma Key. I know that when green screen is used in broadcast televsion, it's a two step consideration:ġ) Get the lighting on the screen itself as even as possible and run it about a stop over the subjectĢ) You have to get some backlighting on the subject themsevles to cut the hole cleanly.

To remove color using the paint bucket tool, first select the paint bucket tool from the toolbar. I've seen two rationales for using a greenscreen with digital: 1) It can be used outdoors without interference from blue skies and 2) the green channel holds more tonal detail, but I'm not sure how those things would apply to our digital photography. In that case it is better to use the white balance slider in your RAW processor. Sometimes your white balance will be off when you took the photo. What's the advantage of shooting against a green screen? I would have thought a white background would be better - certainly in this case.ĭuring the film days they used the bluescreen because blue was the complimentary color to the red and yellow skin tones, allowing them to filter the blue then filter for good skin tones.
