Check the ISO before starting to shoot

Discovering that you’ve accidentally shot a whole series of images in ISO 800 on a bright sunny day can be extremely frustrating, especially if the photos were taken to document a special occasion such as a birthday, anniversary or other event that can’t be recreated. It’s an easy enough mistake to make, though, so to avoid this unpleasant surprise, make a habit of checking and resetting your ISO settings before you start shooting anything. Alternatively, make a habit of resetting this every time you’re ready to put your camera back in its bag.
