Taking Pictures Effect of Aperture By changing the aperture, you can control the depth of the area that appears in focus in the picture (the depth of field). By either narrowing the focus to emphasize a single point or giving depth to your picture instead you can completely change the feel of the picture you create. Use the c (Aperture Priority) mode. Opening the aperture (reduce the aperture value) Objects closer and farther than the focused 3 subject will be more out of focus. For instance, if you take a picture of a flower against a landscape with the aperture open, the landscape in front and behind the flower will be blurred, emphasizing only the flower. Closing the aperture (increase the aperture value) The range in focus expands forward and backward. For instance, if you take a picture of a flower against a landscape with the aperture narrowed, the landscape in front and behind the flower will be in focus. To Use the e (Program) Mode This mode automatically sets the shutter speed and aperture value to the proper exposure according to Program Line. Use the e-dial to change the shutter speed and aperture value while maintaining the proper exposure. 1 Set the mode dial to e. 1D04ownloaded From camera-usermanual.com Pentax Manuals
