Setting the Aperture Value

With the mode dial set to A (Aperture priority mode), you can select the aperture value for your shots. Because adjusting the physical size of the aperture determines the amount of light allowed to enter the camera through the lens, the aperture setting expresses the actual size of the aperture. It is important to remember, however, that the smaller the value of the aperture setting, the larger the diameter of the aperture, and conversely, the larger the value of the aperture setting, the smaller the diameter of the aperture.

Opening the aperture not only allows more light into the lens to compensate for low light conditions but shortens the depth of field as well. Use a large aperture to focus only the subject and blur the background when you want to shoot a portrait. On the other hand, use a small aperture to focus both the subject and the background.

Fine adjustment of aperture and shutter speed

If the brightness is adjusted with fine adjustment of the aperture value, in some cases it may appear that the shutter speed drive is not adjusting shutter speed. The displayed aperture value is the value of the optical aperture, and the shutter speed is calculated based on the CCD’s sensitivity to the brightness of the light to determine the optimum exposure. In order to achieve this, the aperture value and shutter speed may occasionally appear not to be adjusting in fine increments and does not indicate a malfunction of the camera.

Bright spots in the picture?

If you see extremely bright spots in your images caused by sunlight or reflected sunlight, this is a phenomenon called “smear” which occasionally occurs with digital cameras that employ CCDs. To avoid this problem, compose the picture again and try to eliminate the bright light, use a smaller aperture, or use a Neutral Density filter.
