I am having a problem trying to find my built-in isight settings on my macbook pro while I am skyping, or creating any video message or chat in general. I know that it is infact possible to change the effects of your webcam (ex. grayscale, sepia, negative.. etc.) while in a videochat. I was on my friend's mac a few days ago and noticed all she had to do was click somewhere in her toolbar and change the settings, but on my macbook pro there isn't an option to do that. I'm not looking for the photobooth effects; I understand that's a different thing. If this means anything I have the latest version of skype for a mac, the one where you cannot take snapshots either. If anyone could help me out it would be much appreciated
