Click the hyperlink to open up the Workflow Options dialog box and take control of how the image will be opened into Photoshop.
2. Depth – Work in 16 bit mode in photoshop always as it offers 24 million values per pixel where as 8 bit image offers 256 possible values per pixel. Basically means 16 bit offers more information to start with which ensures better print. Quality loss is minimum.
