Expression Blend 3 Features Streamline Photoshop Import

Expression Blend 3 enables the direct import of Adobe Photoshop files, ensuring a smooth integration with traditional workflows the designer may already have in place. On import, layers can be easily regrouped and elements retain their original formats; layers, layer positions, text and vectors remain available for editing within Expression Blend.
