Alien Skin Software has posted Leopard-compatible updates to many, if not of all of its Photoshop plug-ins, including Eye Candy 5, Blow-Up, Exposure 1 and 2, Xenofex 2 and SnapArt. The plug-ins would bring Photoshop down if invoked while running under Mac OS X 10.5.
And, if you’re using Exposure 2, don’t forget to check out the Alien Skin user forums, where there are plenty of additional settings for the film simulation plug-in.
