Having bought this today I am disappointed that not all the green is removed when trying to use this software.
Is there a way that this can be rectified, as if this is the best it will do the software is going to be a waste of money! Any help appreciated,

You need to use the grading effects pill Supression, it should remove what ever green wasn't removed from the composting.

It may also just be a matter of adjusting the settings, or it may be that your greenscreen image has inherent problems.

If you can post an image, we could likely offer more specific suggestions to help you out. Its difficult to say what will fix the problem when we can't see it.

Spill suppression is in the key settings, but it activated by default, so probably isn't the issue here.

As Axeman says, please post up a link to the original image so we can take a look at your greenscreen and lighting. We should then be able to provide some tips to improve the compositing. Problems are usually due to the source image rather than the software.

what kind of greenscreen material are you using? some material is so thin that you will also be lighting the back wall,even a plain white wall will reduce the intensity of the green screen if the material is too thin, pictures or anything hanging on the wall make it even worse.

it is easy to check for balance, just shoot the greenscreen if it looks even go into your favorite editing program do the color picker (you know the eye dropper thing), check the rgb values it should be just about the same all over.
make sure your subjects are far enough away from the greenscreen, mine are usually 9' or more feet away from the screen. the closer to the screen the more problems you will have with shadows it can be be done but you need more lights.

here is a simple hint for everyone,if you have carpeting like I do, my studio is also my home theatre and my living room, go to to the lumber yard and get yourself a four foot square of 3/8 plywood put it under the greenscreen, that way your subject will not look like their feet are a half inch or so into the sidewalk etc.

I have been a photographer for over thirty years if it werent for Photo Key, I do not think I would have recaptured the wonderment that I had the first time I developed a roll of film. in Photo Key 99 percent of the time I do not use anything other than import, position and export
if you want to see my Photo Key work just Google me: Mark Nocera Photographer, it will take you to myspace, look at my photos directory models and stars all models Photo Key, then click on my friend Laura (first picture in friends) all photos that say photo by man are mine only a couple that are not Photo Key you guess what is real, then click on Liz second picture, all shots Photo Key then third row first picture, they call me dime piece, model shots directory all mine all Photo Key
have fun Mark
