When shooting blue/green screen for motion pictures, dedicated matting programmes are usually used to create the mattes and to clean up any stray spill. This shoot doesn't look like a green screen or a blue screen shoot to me. If it was a green screen shoot, the screen would be green. If it was a blue screen shoot, where's the green spill coming from? Can't imagine anyone using a green backlight unless for special fx, like a rock promo! And, IAC, the green here looks more like spill than a backlight. BTW, why would anyone need a "specialist" to do blue/green screen? If you can do photography, you can do blue/green screen work. <g> > It may be worth a quick chat to a video post production house unless there > is someone on the list with video post production experience.

Actually, Photoshop Channel Chops has some good techniques for matting and cleaning up spill. If you don't have it to hand, you can use Hue/Saturation as an Adjustment layer to clean up some of the spill: 1. In the H/S dialog, select Green from the Edit popup menu. 2. Use the Eyedropper(s) to select the spill (make sure its options are set to 3x3 sample size). 3. Move the Hue slider to the left and click the OK button when happy. 4. Change the layer's blend mode to Color. 5. To clean up the edges, do some cloning on a new layer by sampling the hair and change the layer's blend mode to Color and play with the opacity. HTH.
