Exposure Level Increments

This is to change the increments of shutter speed, aperture, and exposure compensation - 1/2 stop increments or 1/3 stop. This setting will also apply to Auto Exposure Bracketing (AEB) and Flash Exposure Compensation. Set this depending on your personal preference and what you are used to using for these increments. Many photographers prefer the greater precision of 1/3 stops, which is generally the traditional and standard setting, but you may prefer the simplicity and ease of 1/2 stops. Shutter speed and aperture will be covered in the Exposure section, and Exposure Compensation in its own section of the text.

recommend: 1/3-stop

ISO Speed Setting Increments

This sets the increments for ISO, either 1/3 stop or full stop. Again, the setting depends on your personal preference and what you are used to. Many photographers prefer the greater precision of 1/3 stops, which is generally the standard setting, but you may prefer the simplicity and ease of full stops. ISO is discussed in the Exposure section. recommend: 1/3-stop

Bracketing Auto Cancel

This determines whether or not Auto Exposure Bracketing or White Balance Bracketing is canceled when you turn off your camera. I recommend that you have this cancellation set for On: Enable, because if you have a shooting session where you are bracketing, then use your camera the next day, you will probably have forgotten that it is set on bracketing, and then most of your shots are going to be improperly exposed. More on Auto Exposure Bracketing later in this text. recommend: On: Enable
