CombineZP vs PhotoAcute Studio

CombineZP is a Windows focus-stacking program that combines focused regions from multiple photographs into an image with greater depth of field. Its documented methods include Do Stack and Pyramid Maximum Contrast. It provides quick and thorough image alignment, with rotation correction in thorough alignment. Batch processing can stack images, and users can adjust memory use for image sets that demand more from the computer. Macro parameters are editable for additional control over close-up stacking. JPEG is the documented output format. The program is free and the repository identifies its license as GPL-3.0. The repository preserves code originally created by Alan Hadley and shared under the GPL; it contains CombineZ5 and combineZP directories, a README, a license file, and an installer. The README refers to a compiled Windows x86 version 1.0, updated January 27, 2012, in a file named combinezp.msi. The repository says it is kept for posterity, lists no published releases, and a microscopy tools page describes the software as not maintained. Windows is the listed platform; a third-party microscopy tools page also says it works with Wine on Linux.

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.
