I know I'm missing something simple here, but I just installed photokey 4 pro on my new machine and it is exporting my images with a black background. On my old machine I had photokey 3 lite and I would; import an image, photokey would remove the green screen, then I would export it so I could finish it in photoshop. Trying that same process now and I get a black background with my image. I watched the tutorial and it just said not to import a background, or to deselect the background before exporting (unless I missed something which is possible). So what am I missing here?

This is a problem which has been known to occur only with TIFF files, and even then only with Photoshop. If you look in the Channels palette in PS you will see that for some reason, Photoshop includes an alpha channel containing the transparency info from PhotoKey, but doesn't apply it to the image. So you have to do it yourself.

If you export to PNG the transparency works as you would expect, and if you open the TIFF files in any program other than Photoshop, the transparency works as you would expect.

Thanks for that feedback, we will make a note that ACDSee software has difficulties with the alphas as well. If your image software doesn't read the alpha channels correctly, you can avoid the issue by using PNG format, which provides lossless image quality.
