Hi all, I'm using the older version of 15" Macbook pro. So it's been almost a year and there's nothing wrong with my isight. However today after I joined robo.to (a website where you can post videos just like how you update your Twitter) and configured my settings when they asked me to choose my webcam. There are 3 choices: USB Video Class Video IIDC Firewire Video DV Video So I chose the USB one. After doing that, I opened my photobooth and realized my isight quality is not as clear as before. I also tried with my iMovie and the quality still remains unchange. I really don't know what to do to recover it. Someone please help!
