![]() ![]() 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. The only dependency is OpenCV, 3.David Leaser's home studio setup with the D850 and 60mm Micro NIKKOR, SB-R200 Speedlights and the SU-800 Commander in place. Most importantly, findTransformECC is used to alignįor more information, see the detailed explanation of algorithms. The application also uses multiple algorithms from OpenCV library. The focus stacking algorithm used was invented and first described inĬomplex Wavelets for Extended Depth-of-Field: A New Method for the Fusion of Multichannel Microscopy Images by B. If you want to provide command line parameters, open terminal and call theīinary with path focus-stack.app/Contents/MacOS/focus-stack. On Mac OS X, you can start the program directly and it will ask for files.Īlternatively you can drag the files over focus-stack application. ![]() Over focus-stack.exe to run with default settings. On Windows you can additionally just select the photos and drag them ![]() opencv-version Show OpenCV library version and build info wait-images=0.0 Wait for image files to appear (allows simultaneous capture and processing) no-opencl Disable OpenCL GPU acceleration (default enabled) batchsize=8 Images per merge batch (default 8) threads=2 Select number of threads to use (default number of CPUs + 1) 3dviewpoint=x:y:z:zscale Viewpoint for 3D view (default 1:1:1:2) halo-radius=20 Radius of halo effects to remove from depthmap remove-bg=0 Positive value removes black background, negative white depthmap-smooth-z=40 Smoothing of depthmap in Z direction (default 40) depthmap-smooth-xy=20 Smoothing of depthmap in X and Y directions (default 20) depthmap-threshold=10 Threshold to accept depth points (0-255, default 10) denoise=1.0 Merged image denoise level (default 1.0) consistency=2 Neighbour pixel consistency filter level 0.2 (default 2) align-keep-size Keep original image size by not cropping alignment borders align-only Only align the input image stack and exit no-contrast Don't attempt to correct contrast and exposure differences no-whitebalance Don't attempt to correct white balance differences full-resolution-align Use full resolution images in alignment (default max 2048 px) global-align Align directly against reference (default with neighbour image) reference=0 Set index of image used as alignment reference (default middle one) nocrop Save full image, including borders with partial data jpgquality=95 Quality for saving in JPG format (0-100, default 95) save-steps Save intermediate images from processing steps 3dview=3dview.png Write a 3D preview image (default disabled) depthmap=depthmap.png Write a depth map image (default disabled) Usage: build/focus-stack file1.jpg file2.jpg. ![]()
