When we select the first option the camera’s first picture will be at the focus point we selected, and then it will pull the focus closer for the next shot and then push it further away for the third. Sequence – By default the sequence is set to 0/-/+, but we can chose 0/+ if we prefer. Fortunately Panasonic has a function in its newer models that is a great help in creating the images needed to feed into focus stacking software – it’s focus bracketing. Computers tend to have greater processing power than cameras, and so can deal with much more complex and intensive tasks so we can choose to shoot in Raw or JPEG formats as we prefer. The downside for some of the in-camera mode is that it produces only a JPEG that has limited manipulation possibilities after the event, and that the system finds it hard to cope with extreme situations.Īn alternative to using the in-camera stacking mode is to shoot a series of images with different focus positions which are then loaded into focus stacking software. It is a useful feature, and with the JPEG colour and contrast controls Lumix cameras offer, it is highly flexible if you take the time to make the most of your settings so that post-capture manipulation can be minimised – or avoided. This feature is accessed via the Post Focus mode, and comes in 4K and/or 6K varieties according to the camera you are using. The only dependency is OpenCV, 3.All current Lumix G models offer an in-camera focus stacking mode that is easy to use and which avoids the need for post-capture software when we want to extend or control our depth-of-field. 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.
