InDesign is Adobe's professional page layout program. You can paste, drag and drop, or place Photoshop files into InDesign. Any paths, masks, alpha channels, and transparency are retained, depending on your file format. You can even use the Photoshop paths to create special effects such as text wraps in InDesign.

Photoshop enables you to specify your image width in columns. Using columns is handy when you plan to import an image into a page layout program like InDesign (or even PageMaker or QuarkXPress) and you want the image to fit exactly within a certain number of columns, based on the established grid of your layout page. You can specify columns in the New, Image Size, and Canvas Size dialog boxes. To set the specific values for the width of the column and gutter (the space between the columns), go to the Units and Ruler panel of your Preferences (under Edit in Windows and Mac OS 9, and Photoshop in Mac OS X).
