Cameras using USB, serial connection, and USB/IEEE Mass storage connections are supported. The camera interface is fast and smooth, with thumbnails to preview the pictures before downloading and, at least with Canon cameras, you have the option to only select new pictures for download. Photos can be organized by albums, date, saved searches, and a completely customizable tagging system.
