Image Capture gives you a second chance to manage photos
Enter Image Capture, a little-used application that comes standard on all Macs. Once you’ve opened it with your iPhone (or other camera) connected, you’ll see a list of the photos in your camera roll. From here, you can choose to selectively delete any of the pictures or everything on the roll, eliminating the need to either remove the photos by hand or throw your iPhone out the window. So this is a cost-saving measure, I assure you.
