Here's a quick and easy tutorial video on how to quickly delete some or all the photos and videos from your photos app on your iPhone or iPad using image capture on your mac. Before doing this, make sure you have a backup of anything you want to keep.
Possible uses for this may be:
1. You want to clear some space for new photos
2. You want to pass on the iphone to someone else without completely erasing it
3. You just want to grab a few specific images or movies without using iPhoto
