Add 24 Hidden Visual Effects to iChat and Photo Booth
With a little bit of hacking and modification, you can add up to 24 additional visual effects to iChat video conferencing and Photo Booth! A reader pointed out this very cool Mac OS X mod and if you like to play around with Photo Booth or iChat effects it’s worth the effort, since it gives you some new nifty options.
To enable the effects first locate the .qtz files in
/System/Library/Compositions and copy them to
/Library/Compositions, if that second folder doesn’t exist you can just create it.
Next you’ll need to drag the files you want to use into something like TextWrangler or another property-list editing capable text editor. In each visual effect that you want to use within iChat and Photo Booth, simply find and delete the array code that follows ‘ExcludedHosts’ that refers to excluding Photo Booth and iChat (see screenshot), it’s usually near the top of the file:
After you delete those lines, save the files and launch iChat or Photo Booth to have the new effects as options. Here’s the full list of the additional hidden visual effects you can enable, 24 in total:
* ASCII Art
* Blue Print
* City Lights
* Color Controls
* Color Invert
* Compound Eye
* Copy Machine
* Dot Screen
* Exposure Adjust
* Film Stock
* Gamma Adjust
* Line Overlay
* Line Screen
* Zoom Blur
As RobG at MacOSXHints.com points out, you can preview each of these effects by opening the quartz files in Quick Look. Personally I think Ascii Art is the coolest just on a purely geek level (above screenshot is this effect on the Mac Finder logo, below screenshot is the ‘Line Overlay’ effect on the Finder logo).
