Setting the Exposure

Effect of Aperture

Adjust the amount of light hitting the CCD by changing the aperture.

Opening the aperture (reduce the aperture value)

Objects closer and farther than the focused subject will be out of focus. For instance, if you take a picture of 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 flower against a landscape with a smaller aperture, the landscape in front and behind the flower will be in focus.

Depth of Field

When you focus on a specific subject, there is a range in which objects closer and farther away will also be in focus. This focused range is called the depth of field.

The depth of field for the GX-1S differs depending on the lens but compared to a 35 mm camera, the value is roughly one aperture setting lower (the focused range becomes shallower). The wider the wide-angle lens, and the farther away the subject, the greater the depth of field (some zoom lenses do not have a scale for depth of field because of their structure).
