![]() In the case of McKenna, I’d probably take one image in each mode in that case and see which one I liked better. However, I would have considered leaving the smart phone camera in its normal mode for taking the shot of Jim McKenna because of the pleasing background. My smart phone has a portrait setting, which I would have used for the image of Harjung. If you don’t own a DSLR or mirrorless camera with manual settings and interchangeable lenses, many smart phones have a setting that allows you to create the blurred out effect. The background isn’t necessarily my favorite, but I felt it was blurred enough for the purpose of this news photo. These settings caused the distracting background to be mostly blurred out. In the photograph below of forest ranger Julie Harjung, I used a lens with a length of 135 and set the aperture to f/2.

If you use the manual setting and set your aperture to a smaller number such as f/2.8, it will create a large opening in your lens, and result in the background being blurry. If you don’t have a good background to work with when taking a portrait, that’s when you often have to rely on using a larger aperture. Meanwhile the mountains behind him were just slightly blurry. This allowed McKenna and the fence to stand out, as they were in focus. In taking this shot, I set the aperture to F/4 and picked a focal length of 70 millimeters. The background was also pretty clean, which is what you aim for with many portraits. In the above photo of Jim McKenna, I was able to find a pleasing background, so I didn’t need to think much about obscuring the background. Choice of background is also important, though sometimes you don’t have good options. ![]() Photographers will use longer lens and large apertures – achieved by setting the f-stop to a smaller number – to get this effect. This method allows your subject to stand out, especially when there is a distracting background. They do this by creating a shallow depth of field, which results in subject being in focus and the background being blurred out. Photographers regularly use depth of field to their advantage when taking portraits.
