The new version is compatible with Photoshop CS4-CS6 64-bit on both Mac and Windows systems. Also two new interface modes (Express and Advanced) have been added.

An Akvis Sketch Home License (plug-in or standalone) sells for US$72. Registered users of the previous versions can upgrade to version 9.0 for $39. Or you can buy the Alchemy Bundle (which includes the Sketch, Chameleon, Stamp, Retoucher, Coloriage, Noise Buster, Decorator, Enhancer, LightShop, SmartMask and ArtSuite plug-ins) for $325.
