I use a sinar camera with captureshop, take a scene reference with the lighting but no subject then Shoot the subjects in place and all the background is gone and even if the lighting is a degredee you only have the shadow that was added by the subject This gives the perfect dropout without any fringing A grey is the probably the optimum for this too edwin -----Original Message----- From: owner-photoforum@xxxxxxxxxxxxxxxxxx [mailto:owner-photoforum@xxxxxxxxxxxxxxxxxx] On Behalf Of Herschel Mair Sent: Monday, February 22, 2010 5:19 PM To: List for Photo/Imaging Educators - Professionals - Students Subject: Re: Chroma key or the traditional black gray backdrop?? Forget Chroma key for stills. It's a video thing and cameras have the facility built in. It requires extremely careful wardrobing and lighting with the background and foreground lit separately plus a good distance between the subject and the background. GREY is the colour for stills if you want to drop out backgrounds. Also, if you want it to be easy in Photoshop, you need to carefully control the lighting. But at least you don't get a green or blue edge tint on your subject. Try and shoot something white or reflective against a green or blue key background and then try and drop that into, say, a grey, white, brown, pink, ivory or cream background in PS... you'll have a nightmnare getting rid of the green edge. If you shot it on a grey background then you can drop it into anything and make it look good with minimal effort.
