Yes, I use Greenscreen wizard for both my PC and Mac (which was released earlier this year) It is very user friendly. I also use express digital darkroom for my fast paced events; but for slower events I prefer greenscreen wizard. It does pretty good with subjects that are wearing green; although you'll have to play with the settings. it takes 3-10 seconds for the software to extract the background. The speed of your processor determines how fast this happens.
