Some wildlife photographers use aperture priority (A, Av) mode to have control over depth of field. Small differences in sharpness can be difficult to notice in the field, and you may come home with important parts of the animal portrait out of focus.If you are close to your subject or using a telephoto lens, too wide of an aperture could result in parts of the animal’s face or body being out of focus because the depth of field is too narrow.Wide apertures create a shallow depth of field, so the background appears softer and out of focusĭisadvantages of using a wide aperture for wildlife images:.Wide apertures allow you to use a faster shutter speed and freeze motion. Advantages of using a wide aperture for wildlife images: If you use the maximum aperture to achieve the shallowest depth of field, you will get the most separation from the background. Therefore, a shallow depth of field is often used in wildlife photography. And like with human portraits, the composition tends to be more appealing when the background is blurred. Typically when photographing wildlife, we are attempting to create a portrait of the animal. This allows you to shoot at faster shutter speeds and maintain a low ISO so as to not introduce noise into the image. The more open your aperture, the more light you will let into the lens. The more important setting you need to prioritize in aerial photography is shutter speed. There is no foreground element (unless of course, you are purposely trying to get some part of the plane in the shot), and so there is no depth of field to worry about in this case. However, when you shoot from an airplane, everything in the scene is effectively at infinity. Generally – yes and yes (remember, “it depends”). It’s usually best to be a stop or two down (higher f-number) from the maximum aperture, but only if doing so allows you to achieve proper exposure and freeze motion, which is important when doing aerial photography.īut wait, doesn’t a wide aperture lead to a shallow depth of field and for landscapes, you want a deep depth of field? Second, to keep your shutter speed fast and your ISO low, the aperture then needs to be wide open, or pretty close to it (typically f/2.8-f/5.6). Just keep in mind the adage, “it depends”. That said, below are general guidelines and starting places to help you choose apertures appropriate for different kinds of outdoor images. You may get tired of hearing, “it depends” as the answer to “what is the best setting for _”, but it is true that the available light, the subject, and your creative decisions change from image to image. If you are new to aperture and f-stops, then be sure to also check out What is Aperture in Photography? Key Concepts Explained and Aperture and F-Stops Explained to get a full understanding of this key camera setting.Īs with many settings in photography, the “best” aperture isn’t always going to be the same one every time. Don’t you agree? However, the array of choices we need make for proper exposure and creative composition can be a little overwhelming or confusing at times. As outdoor photographers, we are fortunate to have so many different subjects and types of compositions that we can create with the natural world.
