ese settings can greatly affect the quality of your image. For the most part, what is being adjusted to nd a proper exposure is the aperture and the shutter speed. Both settings must work in tandem since they both determine just how much light is allowed to hit the image sensor. e aperture is an adjustable opening in the lens that varies the amount of incoming light

hitting the sensor, measured in f-stops. As you open by one f-stop, twice as much light is being let in as the previous f-stop. As you close by one f-stop, half as much light is being let in as the previous f- stop. Shutter speeds also work this way. Apertures also control depth-of-eld, which is the distance in front of and beyond the subject that appears to be in focus. Smaller openings yield more depth of eld and the opposite is true of large openings.

Depth-of-eld is also inuenced by the focal length of the lens, so when you’re shooting in telephoto mode you’ll notice shallower depth of eld compared to shooting with the lens in the wide angle setting.

Shutter speed is the amount of time that the

sensor is allowed to record light hitting it, usually measured in fractions of a second. As with f-stops, each stop on the shutter speed scale will either halve or double the amount of light hitting the sensor when the picture is taken. Digital cameras usually help you nd the correct combination of f-stop/ shutter speed with numerical readout of how many stops you are off by. (i.e. -1 means that you are under-exposing by one stop.)

If you are not using the ash, and your shutter speed is slower than 1/60th

of a second, you should use a tripod or prop the camera on something still. When shooting, use the self-timer function so that you don’t move the camera as the exposure is being made.

Reviewing your work

After shooting a few pictures, it’s a good idea to review them to check the exposure, sharpness, etc.

Put your camera into Playback mode by pressing the playback button, then choose an image to review by turning the control wheel.
