Photo Tip #21-Store Your Camera Setup for Your NEXT Shoot
Come up with basic settings for your camera-ones that you use the most frequently. For example, ISO 100, F/16, aperture priority, RAW/high JPEG, etc. and get in the habit of leaving your camera with these settings in place. If, in the field, you stray from these settings, no worries, just remember to put your camera back to it's basic settings BEFORE you unload it (film or flash memory.)
Remember, it's very easy *the next time* you go out shooting to forget to check these things. Keeping your camera on the same basic setup most of the time, and especially every time you store it, will help ensure you don't accidentally forget and shoot a lot of pictures with your camera on an incorrect setting.
