Exposure – The Basic element of Photography by Nitin Khanna
When photographers talk about “exposure,” we simply take it as the darkness or brightness of a photograph. It looks easy enough to take a photograph that is correctly exposed, but in reality it can be quite the trick.Read on the present blog to help get the right exposure with your camera settings. If you are reading this blog post, it possibly means that you currently shoot on the automatic setting or the Green mode of your camera. This implies that your camera entirely controls the exposure of your shot. In automatic mode, your camera chooses an aperture setting a shutter speed, an ISO setting, and a host of other settings for you. Automatic can be a convenient option, but it seriously limits your creative ability to shoot a stunning picture. All the elements (ISO, shutter speed and aperture or f-stop) of exposure work together and compensate for each other to produce a properly exposed picture. These basic elements of exposure balance each other to create what can be a very well exposed picture. Before we go on, let’s talk about what good or proper exposure means. It is important to remember that the exposure settings on your camera are tools for clicking the photos you want. There is no correct or incorrect way to get the photographs you want.ISO, shutter speed and aperture are like the three legs of a tripod, to use an appropriately photographic expression. As one of these factors varies, the others have to adjust to preserve and accommodate the right exposure. When your shutter speed is very fast, you have to allow more light through the aperture. This can be done by changing the f-stop. If you opt to alter the f-stop to decrease the depth of field, you then have to reduce shutter speed, so the appropriate amount of light gets to the sensor.Something good about the digital cameras is that you can modify the ISO settings. In older times, you had to stick with the same speed setting for the full roll of film. If you adjust the ISO, just be sure to fine-tune the other settings to adjust for the increased or decreased light sensitivity.
Now, as you know why it is so important to have control over the exposure, your next step should be to learn about shutter, aperture and ISO.
