![]() How to Shoot your Stack of ImagesĬompose your image carefully, using your tripod. A good tripod is essential to execute and deliver high quality stacked images, and a cable release is strongly recommended. How can you preserve the quality of the lens’s optimum aperture and yet get the focus depth desired? Shoot multiple images, focusing at multiple different points in the same scene, and stack them together in the computer.įor best results, use all the techniques you know to get a sharp image. The images in this article were all created with a 105mm Micro-Nikkor lens, at f/10, the best aperture for this lens, for this kind of work. If you can’t find your particular lens reviewed, the general rule of thumb is to use an aperture 3 f/stops down from wide open. Multiple lens testing services provide results online, showing what their tests reveal about the very best aperture for a particular lens, so it’s easy to look up. It’s a really good idea to find out what your optimal aperture is when making focus stacks. Find the Best Aperture for Each Lens Before Your ShootĮvery lens has an optimal aperture, which delivers the best possible results. This is why we stack, to get the whole thing sharp. You might try using a still smaller aperture, such as f/16, f/22 or even smaller, but image quality will begin to degrade as the lens is further stopped down, and even then, not all the image will come into focus. Using a smaller aperture would cause more of the image to appear sharp, but much of the image would still be out of focus. In the image above, shot with a close-up lens at its optimal aperture, a particular point of the image is in focus, but much of the area behind and ahead of the point of focus is very soft. ![]() How to Create A Stacked Focus Image Shooting before Stacking ![]() Automated tools are also available, as discussed at the end of this blog post. You can also capture layers through microscopes to use with this technique. This introduction to Focus Stacking centers on the manual method – available to anyone with a camera and a lens that can focus on all the items you want to be sharp in the final image. This technique is most often used for close-up macro work, but can be used in any type of photography where you want objects in the foreground, center, and background to be equally sharp. ![]() It’s easy, it’s fun-and it can be very useful. When a single shot won’t get everything in focus, try stacking a series of differently focused shots of the same scene. ![]()
