For a successful stack, you need sharp images to begin with. Sharpness - Focus stacking is not a magic bullet that converts 10 unsharp images into one sharp image. One thing to observe is that for many not so great stacks, all the factors need to be explored and relying just on buying a more expensive lens is no guarantee of success if all the other factors are not in good shape. Regardless of the software or hardware you're using to create a focus stack, there are certain standout factors that will affect the quality of your final focus stack. Learn Focus Stacking!Īs of March 2017 I'm now doing full and half day workshops covering everything macro, which of course includes focus stacking! If you want to try out Stackshot, WeMacro or MJKZZ stages, or want to learn Zerene and/or Helicon Focus, and spend some time getting to grips with the whole stacking process from a to z, you could do a lot worse than to spend a day doing macro, learning insect praparation techniques and learning to stack. Like anything, there's a workflow and certain amount of preparation that's done before shooting a focus stack. Focus stacking, also known as macro stacking, focal plane merging, z-stacking and focus blending, can be done inside on the kitchen table during winter and is fun to learn, opening new worlds and opportunities for photography. Focus Stacking Walkthrough 1 ➤ The focus stacking workflow 2 ➤ How to prepare a focus stack 3 ➤ How to shoot a focus stack 4 ➤ Software tools for focus stacks 5 ➤ Postprocessing tools for focus stackingįocus stacking is done by amateurs, professionals and part-timers, has applications in entomology, science and astronomy and there's even a camera that focus stacks on the Mars Rover. All you need to start focus stacking is a digital camera, a stage, a flash, your tripod, the right software for stacking and a good sprinkling of patience. Starting out with focus stacking isn't hard, can be done at any time and doesn't need to be expensive. Stacking overcomes this by combining the sharpest parts of several images focused at different points and combining them into one very sharp composite image. There are some fine tutorials on YouTube.Focus stacking is a photography term used to describe the process of combining photographs to obtain images with a much larger depth of field that would be possible in a single photo.įocus stacking as a photography technique is especially useful for macro photography of small objects, because regardless of the f/stop used, the unavoidably small depth of field shooting small objects means that much of your subject will actually be unsharp and out of focus. There are ways to edit out movement in the output image of some stacked photos, and most good software programs have excellent alignment capabilities. ![]() An insignificant movement is fine with outdoor scenes or landscapes, but the less movement the better. Choose a Stationary Subject (Or Edit Out Any Movement) : Focus stacking works best on subjects that are stationary.When the series is finished, the images are run through a good focus stacking software which extracts the well-focused parts of each and combines them into one completely focused image. Several shots are taken while adjusting the in-focus area with each consecutive image. Use Software: Focus stacking doesn’t actually increase the depth of field for the lens, but merely the apparent depth of field in the output image.It’s always best to keep the f-stops as close to the sweet spot as possible. This is true to a point, but beyond that point, the image will suffer because of “diffraction,” or light distortion. Many people believe that by increasing their f-stop numbers and closing down the aperture opening of the lens to f22 or more, they can get a wider depth of field and more of the scene in focus. For my Nikon lenses, it is usually between f8 and f11. Keep the F-Stop Close to the "Sweet Spot": Most if not all lenses have a “sweet spot,” an aperture setting that gives the best quality photos. ![]()
