Focus Stacking Online vs Zerene Stacker

Focus Stacking Online combines photographs of one scene taken at different focus distances, blending the sharp portions into a single image. The maker describes it as free to use in a browser, without installing software. The workflow is to add pictures, choose an alignment method and a reference picture, stack the images, then download the result. Standard and Beta alignment methods are listed; the maker says Beta can perform better in some cases. A reference picture can be selected according to how much of the subject is in focus. The service is described as working on home laptops and smartphones. Focus stacking is presented as useful for producing sharper images, particularly in macro photography, where depth of field can be shallow. The maker recommends keeping the camera fixed because camera shake and scene variation can make stacking harder. A stack may contain two images or more than 100. The homepage also describes a recent stacks gallery and a feature for sharing to social media. FAQ and Contact us links are provided.
