I'm new to photo key and I am trying to add a layer, I have a background image and a foreground image as my subject. But when i add a layer that has been taken on the green screen background it appears with the green screen attached, how do i get the layer image to have the green screen background already removed? Also can I then add shadow cast to a layer image? I was wondering whether I have to save the image that I want to use as a layer into a PNG format, if so can I do this in Photo Key and how do I go about doing it?

You can only key the foreground. Layers have to have alpha channels embedded if you want them to contain transparency. If you want to use multiple greenscreen layers, then you can export each one as a foreground, to a png image with no background, and then import them as layers afterward.

Ok so I have tried that but when I export the canvas it comes up on a white background, not transparent. So when I import it as a layer it still has the white background attached. I'm sure when I first played with the program it gave me options of saving as a PNG file, now it only gives me the option of a JPEG? Maybe I have changed a setting somewhere and not realised? Do you know how to fix this? I can take the images into photoshop to produce a PNG file but if I can do it through photo key it would be so much quicker. Thanks for your help it is much appreciated.

There is a menu in the Export tools that should allow you to choose the format which exported images are saved in. Does the software not let you open them menu, or can you just not select PNG, or do you receive an error when you try? What exactly goes wrong?

Ok cool I have worked the exporting out now thanks for that. When I export the PNG file it comes out on a white background which is fine as when it is imported as a layer the white disappears anyway. But now I have little bits of black lines that are let over how can I get rid of those, have tried using spill suppression but this also takes black away from the image itself anyway of just selecting the areas I want to clean up so to speak?

I'd need to see a sample image to troubleshoot that. Is it possible you could upload one somewhere and give me a link? Or, you could submit a support ticket and attach the image there, and one of us could take a look.
