The advantages over the rail system are fewer moving parts, fewer settings, less gear to carry when shooting on location and no need for power cords or batteries for the rail. This feature, when turned on, will employ focus peaking to create a black-and-white preview stack that can be used to check focus after shooting.) The D850's stack focus feature moves the elements in the lens the camera itself does not move. With the new Z 6 and Z 7 mirrorless cameras, focus shift shooting adds a new feature called “Peaking Stack Images”.
(it's also in Nikon's full-frame mirrorless cameras. Today, David uses the D850 because whether you call it stack focus or focus stacking, the capability is built into the camera. The system did the job: the rail moved the camera and lens, in precise increments, closer and closer to the subject, taking pictures at each interval, with each image capturing a different area of focus. When he first used the technique, he'd mount his D3X and 60mm Micro NIKKOR lens on a motorized rail device that would move the camera and lens toward his subject at preset intervals. What he wanted to capture and share was "a bee's-eye view of nature," and focus stacking was the way to do it. Realizing that even the best close-up lenses couldn't get the depth-of-field he could see in these flowers, not to mention the details even the eye often misses, he started experimenting with stack focus photography. Then, using software, he layered the separate photographs to create a revealing, stunningly sharp, detailed composite image.Ībout ten years ago, while shooting landscapes in the Amazon, David found himself captivated by "the tiniest of living things on the rainforest floor," including the smallest of flowers. To create them, award-winning fine-art photographer David Leaser took multiple images of his floral subjects at different focus points. Stack focus results in the kind of striking photographs you see here. Stack focus, though, is a totally different approach and a means to an end beyond familiar close-up images. You could set f/11, f/16 or f/22 and get a great deal of depth-of-field. What stack focus does is extend depth-of-field in macro photography, and if you're not familiar with the technique, you might wonder why you'd want to do that.
Stack focus, which is also often referred to as focus stacking, is a technique that produces close-up images of depth and detail beyond that seen in conventional close-ups. There's focus, and then there's stack focus.

All the photos with this article were taken with the D850 and the AF-S Micro NIKKOR 60mm f/2.8G ED lens at 1/60 second, f/8 and ISO 64. He uses Wimberley PP-200 plant clamps "to keep the plants steady and position with precision," and floral water tubes for single stem cut flowers to keep them hydrated. Note the LED modeling light at left, clamped to an inexpensive tripod, which he uses during focusing, then shuts off before photography begins.
