Capturing An Out of Focus Background There are several ways to go about rendering the background out of focus. First and foremost it starts with your aperture, which for the most part will determine how out of focus the back ground will be… how wide open is the lens and how much light is hitting the camera sensor. A critical factor to keep in mind the smaller the aperture number, the larger the lens opening will be. This will correspond to the amount of light that reaches the sensor. The higher the aperture the smaller the opening that equates to less light. Another important part of the equation that determines what’s in focus and what’s not is the overall distance the lens is from the subject. For example if the object you’re photographing is as close as possible (meaning in auto focus the camera will lock onto the subject) and the background is a fair distance away from the subject, an aperture of F4.5 will allow the subject to be in focus while the background would be fairly blurry. Although most zoom lens can create a shallow depth of field the preferred lens to achieve the best results would be a prime lens. Prime lens that only have one zoom setting would most likely have a much bigger opening through which light can pass. An easy way to get started would be to set your camera to Aperture priority. (Usually identified as the letter A on the camera dial). I would use the smallest F-stop possible (the biggest opening) I would then increase my ISO a few settings to increase your shutter speed. Step as close to the subject as possible or as much as your lens will allow. Make sure there is enough distance between your subject and the background, which will ensure the results your looking for. At this point fire away!!! My suggestion would be if you looking to shoot with this kind of effect, I would absolutely consider investing in a good prime lens with a very large aperture…the 50MM and the 85MM are my favorites and by far the most versatile.
