That allows you to see all images at the same time making it easy to identify the best photographs taken. Creating a contact sheet on a software like Adobe Bridge is easy as its a simple matter of selecting the images that you want to include and then transferring them to Photoshop. Then selecting a table with the correct number of rows and columns, depending on how many photos you have.
