![]() The result is that, in close-up or macro photography, you are dealing with very shallow DOF. If you want to see DOF numbers for your lens and camera kit, there are several macro DOF calculators online. Therefore, you can say that the factors affecting DOF in macro photography are: aperture, focal length, subject-to-lens distance, and magnification (as part of COC). My hair still hurts from when I wrote about circle of confusion half a decade ago, so I will just say here that one of the factors in the COC equation is “enlargement,” which is interchangeable with macro magnification and the lens’s reproduction ratio. However, with macro photography we are getting into relatively large magnifications of a subject in the image-some macro lenses can project reproductions at life-size or greater. The four factors that affect DOF mentioned in the previous section also apply, of course, to macro photography-the math is constant regardless of what kind of photography you are doing. ![]() Without sufficient DOF, some of the watch face falls out of focus. If you want to stay on this channel, keep on reading. ![]() If you want to take a super-deep dive into DOF, please see my three-part series on the subject starting with this article. The four primary factors that determine DOF are: lens aperture size, lens focal length, the subject-to-lens distance, and a concept known as circle of confusion (COC). That linear distance before and after the focus plane is the DOF. Depth-of-Field Basicsīefore we dive in with macro DOF, let’s get the basics of DOF out of the way.ĭepth of field is defined as the area in a projected image, forward and aft of the focal plane, which also appears to be in focus in the image.īasically, the camera lens is focused at a single distance from the front of the lens and the human eye sees an area before and after that distance in sharp focus. Large magnification macro lenses often have DOF distances that measure in the millimeters or less! This means that a photo of an insect or small creature might show the eyes in sharp focus, but nearly everything else is a blurry haze. In the world of macro and close-up photography, however, a shallow DOF shot can be the photographer’s nemesis. To accomplish this, there is the grail quest for lenses with larger and larger maximum apertures. Let us know if you have any additional tips.Shallow depth of field (DOF) is one of the visual effects that many photographers seek in their everyday photographs. Naturally, avoid changing lenses in the wind, at the beach, desert or other sandy and dusty places – if it’s possible. Have your camera facing down while doing it so less dust will get trapped inside. AdvertisementsĪlso, when changing your lenses, make sure to have everything prepared so you can do it as quickly as possible. This will make the dust spots more visible so you’ll know where to look for them. Set your camera on Aperture Priority, use low ISO, and a small aperture like f/16 or f/22. It can also be a piece of plain white paper if you’re shooting indoors. Before or after you’re done shooting, take a photo of the sky. So, if you do have some dust spots and won’t be able to get your sensor cleaned for a while, here’s something that crossed my mind. This is why I won’t tell you “keep your sensor clean.” It goes without saying, but sometimes it’s easier said than done, especially if you don’t want to mess with it yourself. Since there is no camera shop that performs sensor cleaning in my hometown, I have to go to the capital when I want to have my sensor cleaned. It also works by just hitting the Copy and Paste buttons beneath the edit history. Then, select the rest of the photos and right-click, go to Develop Settings > Paste Settings. Click Ctrl/Cmd + Shift + C to copy settings, uncheck all, and only check Spot Removal. Now, go over the dust spots with your brush until you clean all (or at least most) of them. Or you can just hit A on your keyboard to make it happen. At the bottom of the image you’ll find the “Visualize spots” tool which will help you see the dust spots more clearly. It should be one without too many details so that you can easily see the spots. When you import the photos into Lightroom, choose the one where the dust spots are the most prominent.
