In the olden days of photography, a true student of the hobby would carry a note pad and write down the shutter and film speed as well as the lens setting and information such as whether or not a flash was used. The photographer would then use this information as a reference in becoming familiar with the camera.

Even with digital it is extremely important to learn how your camera reacts in various settings. Digital cameras often have very hot flashes that wash out a subject if it is too close. Other cameras may be picky about shooting strange lighting.

Whether a photo comes out perfect or awful, it is often useful to be able to go back and see how your camera was setup for the shot. Your digital camera automatically records such information but you have to know where to find it.
