Q: Photobooth greenscreen doesn't work with Logitech C615 Web Camera

Apr 26, 2013 8:09 AMby EZ Jim,One or both of these may help you.
(1) Perhaps you installed some additional software on your Mac mini to control your Logitech?
If so, that software's driver may be overriding the Mac OS X webcam software and causing trouble with the "fixed focus and exposure and white balance" requirements for using Photo Booth's backdrops shown in http://support.apple.com/kb/PH5610
As one example, Logitech's http://tinyurl.com/ckfesn7 Troubleshooting page advises that their software may limit compatibility with some applications, Photo Booth included.
If you have installed any software beyond that automatically installed by OS X, follow the supplier's instructions on now to uninstall it, restart your Mac, and test again.
(2) Your problem can also be caused by small, even tiny, movement of your camera:

Movement in the camera's background field of view, even air moving pictures or curtains behind you, can also cause this.
Make sure everything is absolutely still, restart, and test again.

1. I did load the Logitech software that came with the camera only because the sound (microphone) was not recording when I first attached the camera to my Mac. After loading the Logitech software all seemed to work perfectly until I found the problem with Photobooth.
I went and uninstalled the Logitech software and rebooted. Upon finishing the reboot I once again tried to use the Rollercoaster effect in Photobooth. This time it gave me the message to "move out of the frame" (before I never saw this message) and after about 2 seconds it then told me "Detecting background". Alas, the user still does not show up in the video.
Unfortunately, the problem still persists. Now, it flashes the message to move out of the frame for less than one second and then shows the detecting background message almost as quickly. If I move to another background, say going from Rollercoaster to Eiffel Tower it does not even give either of those messages.
2. I also tried moving the camera to another location near my Mac that would be unaffected by any user movement. Unfortunately, this did not help either.
3. Just to be sure I hadn't missed something, I also removed the com.apple.PhotoBooth.plist file once again - still no go.
Any other ideas?

A few seconds after you moved out of the frame, you should have seen a message "Background Detected" rather than "Detecting background". (See the first ¶3 in http://support.apple.com/kb/PH5891)
You can move back into the frame once Photo Booth has detected the background. If the picture does not look right after that, see http://support.apple.com/kb/PH5900
If you really see "Detecting background" while you are out of the frame, your software may be damaged. Reinstall all your Mac's software or see your Apple Authorized Service Provider for help.
