Most digital cameras offer a feature to save your personal set-up or several set-ups: MR for Sony, U for Nikon, C for Canon. Usually accessible on the Mode dial, you can instantly dial up a group of camera settings that you used before and saved. For example, you start with Aperture Priority mode. Set your starting point for aperture. Then dial in ISO, metering, focus mode and area, along with other settings. Save those settings, and you can dial them up quickly when you’re out shooting wildlife.
