One day I received a question from a National Association of Photoshop Professionals (NAPP) member. He asked if there was a better way to crop large numbers of photos that he'd scanned. He went on to explain how he'd spent hours gang scanning photos into his computer and then cropping each one individually in Photoshop. To his surprise, I replied that this could be done with an automation that was already built right into Photoshop.
Place multiple images on your scanner and scan them into your computer. The Crop and Straighten Photos automation will tend to work best on photos with clearly defined edges, so keep that in mind. When you scan them, you should get a single file with multiple photos in it.
Open the scanned image in Photoshop. I know I said we were going to use Bridge in this chapter, but this is one of the few automations that isn't included in Bridge (again, I have no idea why) so you'll have to use Photoshop here. Now, you can use this feature in one of two ways. First, you can draw a selection around the images that you want to crop and straighten and Photoshop will only use the photos in that selection area. Or you can just use an entire layer, which is what I use the most. Then, from the File menu choose Automate>Crop and Straighten Photos. The automation will start processing your photos and placing each one in its own window.
