Once you’ve imported the photos from your iPhone’s camera roll into your iPhoto library, you’re presented with a choice: Should you delete the pictures from your phone or keep them there? It may not sound like this is a weighty decision, but if you’ve ever chosen poorly, you know what a headache it can be to get that darned camera roll clean again after keeping photos on it.
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.
