How to Focus a Camera for a DSU

How to Focus a Camera for a DSU

A properly exposed and focused picture requires the correct speed, aperture and focus settings on your computer. Because all of these settings affect each other, you must adjust them all for proper focus. When using a digital slave trigger unit, or DSU, which offers remote flash, you must adjust the aperture differently than when taking pictures without a flash. The DSU adds light to an image but does not add light at a consistent rate, depending on the brightness of your surroundings. Because of this, you may have to try several aperture settings before finding the perfect focus.

Instructions

    1

    Attach the DSU to the digital camera.

    2

    Turn the camera on by pressing the "Power" button. Point the camera at the subject.

    3

    Adjust the knob of the camera that allows you to focus. Adjust the focus until the subject you want to capture is the sharpest. If you are taking a picture of a person, make the eyes the clearest part of the photograph.

    4

    Hold a light meter over the subject, and take the f-stop and shutter speed reading.

    5

    Turn the shutter-speed dial to the suggested amount. Tun the f-stop to the number just below the suggestion on the light meter. This will adjust for flash. For example, if the light meter recommended an f-stop of 4, turn the dial to 2.8.

    6

    Click the shutter release button to take a picture. Examine the focus of the picture. If the area you wanted to focus on is not in focus, repeat the process of adjusting the focus.
