![]() You’ll probably be using a narrow aperture to achieve a deep depth of field. Here are some tips regarding focus peaking for a few different scenarios. When To Use (And When Not To Use) Focus Peakingįocus peaking is a tool, and like most tools, it can be used properly and improperly. Experiment with different colors on different scenes to find out what works best for your scenario. This is useful when certain overlay colors might not show up as well as others, depending on the scene. Most cameras have red, yellow, and blue as options, but some have more. The other useful parameter you can usually change is the color of the overlay. Fewer areas are overlaid with blue pixels, allowing the photographer to specifically target specific portions of the frame for the sharpest focus. Many portions of the scene are overlaid with blue pixels indicating sharp focus. ![]() In an opposite example, landscape photography at f/22 will have a large portion of the image in focus, and a lower sensitivity might be useful so that you can see more of the image itself rather than just color overlay. For example, if you’re doing macro photography at f/1.8, only a small portion of the image will be in focus and a higher sensitivity might be useful. This is useful because some scenarios will not have many areas in focus. The two most common parameters are the sensitivity and the color of the focus peaking overlay.īy changing the sensitivity or level of the overlay, the algorithm will either have a higher or lower sensitivity to the areas of highest contrast. Most cameras have adjustable focus peaking parameters, which you should use to your advantage depending on the scenario. The areas of low contrast are not in focus, so they will not have a color overlay. In the most simple terms, the areas of high contrast are in focus, and therefore will have a color overlay. A focus peaking algorithm digitally analyzes the scene, looking for areas of high and low contrast. The mechanism behind focus peaking is logical. The aperture is f/1.8, but there is enough distance to the subject so that the depth of field is sufficiently wide. Online camera stores often have external camera monitors on sale around holidays. Before purchasing, ensure that the monitor has built-in focus peaking and that it is compatible with your camera. Simply plug in the external monitor to your camera and access focus peaking on the monitor itself. The biggest downside is that they aren’t the cheapest accessories, but if you find yourself needing a way to check your focusing accuracy, you may want to consider an investment. Since videography has used focus peaking for a while, most external monitors meant primarily for video have focus peaking. ![]() If your camera doesn’t have focus peaking built-in, you are not out of luck. Make sure to read your camera’s manual, looking for anything under “focus peaking,” “peaking highlights,” “focus assist,” or general focusing aids. While every camera is different, it’s important to note that your camera may not have focus peaking. To switch your lens to manual focus (provided that you have a lens with autofocus), find the switch on the lens that has AF and MF, and switch it to MF. Most cameras will have focus peaking settings grouped with other focusing settings, and some will only let you access focus peaking when your lens is in manual focus. This is useful in situations when you aren’t sure what aperture will give you the depth of field that you want. In this case, focus peaking will overlay color on a large part of the image. In this scenario, focus peaking will only overlay color on a small part of the image.Īt a narrow aperture, such as f/22, the plane of focus is large, and a large portion of the image will be in focus. At a wide aperture, such as f/1.8, the plane of focus is small, and only part of the image will be in focus. ![]() In addition to helping photographers determine what parts of their image are in focus, focus peaking also helps visualize the effects of changing aperture. Another example of focus peaking providing its visual indicator overlay for changing planes of focus.
