If you like, you can custom-tailor your white balance (color balance) and ISO (sensitivity) settings. To start out, it’s best to set white balance (WB) to Auto, and ISO to ISO 200 for daylight photos, and ISO 400 for pictures in dimmer light. You can adjust either one now by pressing the WB or ISO buttons on the left side of the back of the camera, and rotating the main command dial until the value you want appears on the top-panel LCD.
