Focus stacking is similar in principle to HDR photography. I enjoy demonstrating the capability of using a program such as Photoshop or Lightroom to extract single frames from 4K video clips, then creating beautiful 13×19-inch prints from the frame grab. For better quality at higher ISOs, whether needed for faster shutter speeds, more depth of field (a smaller aperture) or low-light conditions, the full-frame camera usually wins. The technique is called “focus stacking,” and until the recent new camera models hit the market, focus stacking could only be done manually. If you choose too large an increment, the image may be softened. Focus stacking lets you take several photos of a landscape, focused at different points, and combine them together into the sharpest possible image. It allows you to get more of your subject to appear in focus (more depth of field). Focus stacking is what you do with your series of photos after photographing them using focus bracketing. Although dedicated focus-stacking software has been around for a while, the hard part was getting suitable high-quality image files. When shooting macro, DOF is extremely shallow. The newest Panasonic Lumix and Olympus OM-D cameras also have this capability. By clicking Sign Up, you are opting to receive promotional, educational, e-commerce and product registration emails from Nikon Inc. You can update your preferences or unsubscribe any time. Focus stacking is frequently used by macro photographers, but it is also a great tool for landscape photographers. The D850’s handy “focus shift” feature is used chiefly to create the images for focus stacking, which are then combined in optional third-party software to create a final image with extreme depth of field. The Nikon mirrorless range also has focus bracketing in-camera. Using focus stacking software, an image was created in which the entire nameplate is in focus. The stacking process would vary from one camera to another. I adjusted the number of images to 140 and the increment scale to 3, and the Focus Bracketing in the EOS RP still worked perfectly. The Starting storage folder menu contains two options: New folder and Reset file numbering. You just shoot a series of images, shifting the focus a little between each shot and then merge the images so that only the sharp areas are visible. Best times and locations to photograph in Porcupine Mountains Wilderness State Park, Michigan. Some of the newest cameras now offer focus stacking as well. Focus Stacking in Camera. Built in focus bracketing is more important than focus stacking in the camera, although both would be nice. These however will be largely invisible except when the image is zoomed in at an extreme zoom of 400% - 800%. Macro lens focus stacking. It's a pretty easy technique. Now the industry has incorporated in-camera focus stacking features in a number of ingenious ways; it’s offered cameras including Panasonic LUMIX, Olympus OM-D, Nikon’s Z 6, Z 7 and D850, and Canon’s new entry-level, mirrorless full-frame EOS RP camera. A few popular cameras with this feature include the Canon Eos RP as well as Nikon Z6, Z7, and D850. The most practical (if not most aesthetic) answer is, it depends on how the images will be used. What if you have a home printer or send your images to a professional printer for enlargements? Thread starter Richard_R; Start date Aug 15, 2020; Richard_R Eclectic eccentric. But read on for another perspective. Use software such as Nikon’s View NX-i to view the photos and select the files you want from each sequence. Macro photography and particularly focus stacking enables you to see intricate details of tiny subjects. While we may insist upon 20 to 50MP frames from our DSLRs, the frame-grab exercise demonstrates that you can crop a 20MP camera image to 50 percent of the original file with great results for display as moderate enlargements and on social media. Note that this is simply the maximum the camera will take. Having completed the test at 1x with excellent results, I took it one step further and added a Canon EF 2x III extender to the 100mm macro for just a bit less than 2x magnification. Focus stacking or focus bracketing, as it is also known, is where you shoot multiple images of one subject with a slight change in focus point. This is an interesting question that goes to the heart of choosing and using digital cameras optimally in various photographic situations. As faithful readers know, I’ve been working for years on a project to document a bald eagle nesting site not far from where I live in Central Oregon. Focus stacking can be effective in two very different contexts. movie live view: switch to live view photography, interval timer shooting: end interval timer shooting, multiple exposure: end multiple exposure shooting. The Nikon D850 also has this capability. The default setting of “Off” is recommended in most situations, but you can choose “On” if you have no choice but to shoot under changing light conditions. However, manufacturers are beginning to introduce in-camera focus stacking. The beauty of this camera function is that it offers precise focus-stacking capabilities right in the camera for landscapes and macro, even up to 2x. Longer intervals are only needed to force the camera to wait when, for example, each photo uses the flash and you need enough time between shots for the flash to charge. Whenever you need more depth of field than you can get with trading off image quality, this is the way to work around it. Focus step width: 1; number of shots: 36 (taken with the D850), Focus step width: 2; number of shots: 11 (taken with the D850), The Focus shift shooting menu on the D850. To expand my knowledge beyond Canon, I went to a friend who has both a Nikon Z 6 and Z 7, both cameras featuring what Nikon calls Focus Shift Shooting. However, with focus stacking, images are captured with different focus points and later combined in Photoshop; this is in order to create an image with more DOF than would be possible with a single exposure. Post Focus will run a little video capture that will make an image with approximately forty focus points. In the focus shift shooting menu, you have the option of choosing a new folder and resetting the file numbering to 1. Lepp captured this image of a bald eagle feeding its chick on 4K video from a distance of more than 200 feet. Even at f/22, the area of sharpness is pretty shallow. Stay up to date on all the latest photography gear! I have been taking macro images of insects, plants and fungi for many years, using a full-frame camera with a 90mm macro lens. For Canon users, Digital Photo Professional 4 will do the compositing (this software comes with the camera at no additional cost), while photographers who have already been working with this technique may prefer specialty software such as Photoshop CS, Zerene Stacker and HeliconFocus. The Focus shift shooting menu on the D850 showing the various settings that can be adjusted. The following Olympus cameras have built-in focus bracketing and focus stacking. Many modern Lumix models offer a Focus Stacking function that helps users to precisely control the depth of the zone of sharp focus in their images. You’ll want to disable any features that could interfere … With focus stacking software you can make your usual camera render results that could not be achieved even with a classic tilt-shift lens. You’ve successfully subscribed to Nikon’s Learn & Explore newsletter. of shots. Focus stacking is frequently used by macro photographers, but it is also a great tool for landscape photographers. The Helicon Focus software rendering display. Not many folks have access to, or are willing to haul around, this kind of photographic gear. If so how? Sign in or create an account to access your information. The output images from the EOS RP can be in RAW or JPEG format; considering the number of images often required to complete the task, I usually work with large JPEG files when focus stacking. The focus-stacking process begins post-shooting with image selection. Built in focus bracketing is more important than focus stacking in the camera, although both would be nice. Once all images are shot, you will need to select the photos to use for focus stacking from the many shots you took at different focus positions, starting with the closest and ending with the farthest. Here is a photo of one of those NGK spark plugs. Yet my photographer and bird-watching friends come out to photograph the nest with 100-400mm lenses (sometimes with a 1.4x attached) and send me excellent close-up images that rival my megabuck, mega-millimeter images. This article explains about how it works and how to make the most of it. Of course, when it comes to getting the shot, the APS-C camera will likely have a few advantages of its own. It’s because sharing images through email or social media requires only a very small file, which allows the photographer to crop extensively…if the original capture is well-exposed and sharp. That feature has been included and improved in the E-M1 and E-M5 series of cameras. In my initial test of the in-camera technique, I used the EOS RP to take macro shots of some flowering plants. In the focus shift shooting menu, you can adjust the focus step width. I disabled Exposure Smoothing as recommended in the manual for the Canon 100mm and 180mm macro lenses. Assuming that the APS-C sensor (with a 1.5x to 1.6x crop factor) has 20MP resolution and the full-frame sensor has 30 MP, when the resulting full-frame image is cropped to match that obtained from the APS-C sensor, the two files will contain approximately the same amount of data and comparable sharpness. To adjust focus shift settings, go to the photo shooting menu and select Focus shift shooting. And regardless of your preferences for manufacturer or post-capture assembly, the resulting images will be sharper, have the precise amount and positioning of depth of field you want, and will greatly increase your technical and creative options. Years ago, I was asked by the folks at Canon what features I’d like to see in future cameras, and one of my suggestions was an automated focus-stacking capability—dramatically increasing an image’s depth of field by combining multiple captures taken at different focus points. Given the same aperture and a lens focal length chosen to produce the same picture angle, the large image sensors in FX format cameras and the like will show a shallower depth of field than smaller sensors, so you really have to stop the aperture down to get a deep depth of field. We set up the Z 6 and accomplished the same series of images that I had done with the Canon EOS RP, also with great results. It can be tricky to choose the minimum number of shots needed based on the lens focal length or focus step width, but you can take some of the pressure off during shooting by taking a large number of photos with the idea that you can choose the ones you want during focus stacking. Take several shots at different focus distances instead of just one, and Helicon Focus will quickly and smartly combine the stack into a fully focused image. Perhaps they could have gone for … In these circumstances, the way to get good depth of field without stopping the aperture down so far that pictures lose definition is by focus stacking. Because we don’t need to worry about getting a deep depth of field with a single photo, we can instead consider how aperture can be adjusted to produce a high-resolution, high-definition image with each shot. Handheld focus stacking is a brilliant solution for many scenarios. All current Lumix G models offer an in-camera focus stacking mode that is easy to use and which avoids the need for post-capture software when we want to extend or control our depth-of-field. This feature is accessed via the Post Focus mode, and comes in 4K and/or 6K varieties according to … Exposure smoothing adjusts exposure to smooth out changes in subject brightness that may occur during shooting, but really you want all the photos in a focus stacking sequence to be shot under the same lighting and other conditions in the shortest possible period of time. How small can you go? I would like to use in-camera focus stacking when taking low light landscapes with wide apertures so would appreciate any help with this. When using focus shift, you’ll mostly be photographing stationary subjects with the camera on a tripod, and you can either choose silent photography or shoot with the regular mechanical shutter. Staff member. The amount the focus distance changes with each shot is not determined solely by the focus step width but is calculated by the camera based on a variety of lens data, including focal length and aperture, so it’s probably best to experiment until you get the hang of it. I've followed @Dan Bailey 's book and the Fuji manual and wasted a massive amount of film with no luck. The software will render the final image. There’s no moving the camera, manually changing focus, or repositioning the subject. As with manual focus-stacking techniques, the in-camera capture sequence is later transferred to computer-based software for compositing into a single high-definition image. It’s a time-consuming process. The strips of in- and out-of-focus areas are visible at four- or eight-hundred percent zoom (f/4.8 with a focus step width of 10). Focus stacking or focus bracketing, as it is also known, is where you shoot multiple images of one subject with a slight change in focus point. Some cameras do the entire focus stacking process in-camera. At high magnification, depth of field is extremely shallow, so in the Focus Bracketing Menu, I selected 40 shots, with the focus increment set to number 4 on the scale. Macro & Focus Stacking With the help of CamRanger, get your macro shots in micro time. Starting with the interval between shots, “zero” is basically a good choice. Focus stacking is a task for the heaviest hitting photo editors, such as Photoshop. Other Olympus cameras like the OM-D E-M1 Mark II and E-M5 Mark III also have In-Camera Focus Stacking. Focus stacking combines multiple images at different focal lengths to eliminate blur and keep all elements within an image crisp and clear. Among the current models, most cropped sensors (APS-C size) are around 20 megapixels, and the full-frame could range from 20 to 30MP or more. ! It would be so easy, just bracket focusing, taking a bunch of shots, … Focus stacking is generally performed using Adobe Photoshop or other generic image-processing software or dedicated stacking software such as Helicon Focus from Helicon Soft or Zerene Stacker or Combine ZM from Zerene Systems. If the full-frame camera has a higher resolution, such as 46 or even 50MP, then the cropped image from the full-frame camera will contain more detail—an important advantage when the files are enlarged. […] But first, let’s look at all the variables that can affect the outcomes, beginning with differences in pixel counts. Plus, cropping versus smaller sensors and file size considerations, One of North America’s best-known contemporary outdoor and nature photographers and a leader in the field of digital imaging and photographic education, Lepp is the author of many books and the field editor of. Is a larger image file worth the cost of large sensors, higher resolution, extra sensitivity and lots of technical calculations? You will be surprised at what is possible even in these situations.
