Simply exposure is about understanding exposure as it relates to photography, particularly digital photography. Once the concept of exposure is understood, you will experience a "light bulb moment". You will understand the relationship between shutter speed, aperture, and ISO settings to provide the perfect exposure for each shot. I have used the Nikon DSLR camera as an example throughout the book to explain menu settings. You will need to refer to your own camera's menu settings, if you have a different camera.
