PhotoBooth is an excellent utility from Mac which allows you to take quick pictures from iSight camera of Macbook or any other USB webcam. Although the images are quite plain and if we want to add effects to those images then we’ll need to dip our hands dirty into image editing field and trust me that’s not at all easy!
Well, for lazy people like me software or utilities like CatEye come pretty handy. This utility puts various effects in photobooth and iChat. So if you want to take a still photograph showing the retro effect then it will be as simple as clicking a picture from Photobooth or while chatting with your friends you can show these wonderful effects through the iSight webcam.

CatEye package comes with RetroPixels, Love for 80s and Bent Pels effects packages and is pretty simple to install, just extract the .QTZ files into the folder /Library/Compositions. That’s it and when ever you’ll open PhotoBooth or will launch iChat, it’ll show you the list of effects like you see in the above given image.
