Focus Stacking Online vs PhotoAcute Studio

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.

PhotoAcute Studio processes sets of photos, especially continuous-mode shots, to create high-resolution images with reduced noise. Its superresolution feature combines frames to increase spatial resolution beyond a single source image. Combining photographs can also reduce noise while retaining detail. For exposure-bracketed images, HDR processing can restore shadows and clipped highlights, including when photos are misaligned. Focus stacking combines images taken at different focus distances to increase depth of field. The software also corrects geometric distortion and chromatic aberrations and can remove unwanted moving objects. It supports automatic alignment and batch processing, with RAW, JPEG, TIFF, and OpenEXR output. The maker describes RAW-in-RAW-out processing for fitting results into an existing workflow. Trial mode allows use of all image-processing features, but stamps saved images; the guide says the trial has no time limit. The paid product has no free plan. It runs on Linux, macOS, and Windows; its v2.96 download page lists Windows and Mac OS X, with Linux supported via Wine.
