In this step-by-step focus stacking guide, you’ll learn what focus stacking is, how to apply this technique on location, and how to use the best focus stacking software. I felt the same way too, but once I learned how to focus stack my images, I was able to add more depth and increase the sharpness in my photographs. The only dependency is OpenCV, 3.Home | Photography | Photography Guides | Focus Stacking in Photography – Complete Step-by-Step Guideįocus stacking is a technique that opens up a whole new world of possibilities for your photography.įor many photographers, learning how to focus stack images may seem intimidating and, like something only pro photographers can do. 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. Minimal configuration of -threads=1 -batchsize=2 uses about 50 MB per megapixel. It is affected by number of images per batch, and number of simultaneous Memory usage can be reduced at the cost of computation speed. Of images in stack does not significantly affect memory usage. The images are processed in batches, so total number With default settings, approximately 100 MB of RAM is required per 1 megapixel 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 extrapolated border 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.
