One thing I just tried for zPhoto. Putting all the effects on at once. It basically comes out a garbled mess. I’ll probably have to take out the extreme ones like pop art for it to work, or do it first. And Sepia and Black and White kinda cancel each other out, plus if you remove or modify the color thermal doesn’t do anything but make it all bluish…so I really don’t think its worth it to put in an “all” filter.
The only reason I say this is because I saw ‘photobooth all filters on at once’ in my referral search strings, so I tried it out.
