Does someone know if you can export the extracted subject of a Chroma-Key photo done in PhotoKey3Pro on a transparent layer or just as the cut out subject instead of on a solid colored background?

If so, can you explain?

Thanks in advance

Yes you can. If you don't import a background, then when you export there won't be one, if you export to a format which supports transparency.

JPEG does not support transparency, so you cannot use jpeg for alpha export.

Both PNG and TIFF will work, however, with TIFF there is another detail which should be mentioned. For some reason, if you open the TIFF in Photoshop, it won't appear to have a transparent background. Every other program I've tried handles it correctly, except Photoshop. In Photoshop, the alpha info is stored in an alpha channel assigned to the background layer. So the info is there, it just has to be applied to the channel manually to remove the background from the image.

Thank you! I really appreciate the help. I am just starting to learn how to use this program tonight and I am really loving it so far. I have not mastered the green spill controls. When you apply changes the image pixelates until you are done with whatever change you are making, and that makes it more difficult to compare a "before and after" of an edit. I am sure I will get used to it.

Luckily the image I started off with did not have any spill, which helps I am sure. Proper set up is most likely a key to success in any background removal scenario.

Thanks again! I am sure I will have more questions the deeper into this I get. Hopefully I will be able to contribute answer too as I learn more.

Any way around the pixelation described above that you know of?
