That means that both the foreground and background are in focus but it’s less sharp than desired. Well, despite more of the image being in focus, the actual sharpness isn’t as good. This surely sounds great and you may be asking “Christian, why isn’t this the optimal aperture then?” I.e., there aren’t parts that are blurry or out of focus. You might have guessed that using this aperture will result in more of the photo being in focus. That means we’re looking at a higher f/stop number such as f/22. What is a Narrow Aperture and When Should You Use It?Ī narrow aperture is the opposite of an open aperture. Keep in mind that how blurry elements become will depend on where you focus (foreground, middle, background), how close the foreground element is to your lens and what focal length you use (wide-angle vs. There’s not much natural light available at night, so you’ll need to increase the ISO, use a slower shutter speed and use an open aperture. Next, place your camera on a tripod and take some test shots to compare.Īn open aperture was used to blur out the foregroundĪnother common example of when an open aperture is ideal is during night photography. So, have a look at what the widest aperture of your lens is and use that to calculate the optimal aperture for overall sharpness. Since the majority of professional lenses have the widest aperture of either f/2.8 or f/4, you’ll often hear that the best aperture is either f/8 or f/11. A faster lens, such as the 14-24mm f/2.8, has a sweet spot between f/5.6 and f/8. This spot is located two to three f/stops from the widest aperture.įor example, the sharpest aperture of the Nikon 16-35mm f/4 is between f/8 and f/11. The sweet spot of a lens is the aperture that gives the best overall sharpness. I recommend reading our Introduction to Aperture in Landscape Photography for further understanding of this subject. As an example, the HD Pentax-DA 35mm Macro goes from F2.8 to F22. When referring to the sharpest aperture, I’m referring to the point in which the overall image is at its sharpest. No lens has all the F-stops shown above any given lens covers a smaller range of the scale. Note: in this article, we’re talking about overall front-to-back sharpness not Depth of Field sharpness. The best aperture for my system might not be the same as for yours. If you’re just learning about aperture it might sound confusing that the sharpest aperture depends on the lens you’re using. Let’s take a closer look at what this is before we move over to the situations you want to use it. It’s at that setting you’ll find the greatest front-to-back sharpness with your setup. But if you want to focus on one person, consider using a shallower depth of field.Step one is to find your lens’ sweet spot. If you’re looking to take a picture of a busy street, a higher f-stop will probably work better for you. Street photography settings depend on what you’re trying to capture and how high or low your shutter speed is. f/8 is usually a good starting point for most cameras, but depending on the landscape, you can push the aperture slightly higher if you feel like more should be in focus. When photographing landscapes and skylines, you want to get as much of the image in focus as possible without losing detail. You might need to compromise focal length if shooting free-handed, as taking photos below a specific shutter speed without a stable surface is almost impossible. When taking photos at night, The Exposure Triangle is fundamental.
