Aduku Stacker vs PhotoAcute Studio

Aduku Stacker combines photographs taken at different focus distances into a sharp image, for macro, product, landscape and microscopy photography. The free app offers five merge methods: Wavelet, Pyramid, Weighted, Hybrid and Depthmap. Its default workflow processes images at 16-bit and uses 32-bit floating-point merge calculations, with memory-bounded batching for deep stacks. Automatic alignment uses feature matching and subpixel refinement; options include focus-breathing correction, homography, mesh warp and manual alignment seeding. It imports JPEG, PNG, TIFF, BMP, HEIC and DNG, and exports JPEG, PNG, TIFF, linear DNG and depth maps. Proprietary RAW files may require Adobe DNG Converter on macOS. Retouching lets users paint from aligned source frames, erase strokes and undo or redo, but there is no clone tool. Processing is local and does not require an internet connection. It runs on macOS 13 or later and 64-bit Windows 10/11; 8 GB RAM is sufficient for most stacks, with 16 GB recommended for deep 16-bit RAW stacks.

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.
