CombineZP vs Helicon Focus

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.

Helicon Focus combines photographs captured at different focus distances into one image with extended depth of field. It is designed for focus stacking in macro and micro photography, close-ups, jewelry, products, landscapes, flowers, animals, and still life. The software processes images at 16-bit precision, supports color profiles, opens RAW files, and can save Pro results as DNG. It handles stacks of hundreds of high-resolution images and supports unlimited stack length. Retouching tools copy areas from aligned source images or combine areas from outputs, with a grid for detailed work. Batch rendering can queue and split stacks, while command-line parameters allow calls from other applications. Lightroom and Capture One plugins export stacks. Pro features add 3D model export and 2D micropanorama stitching. Current downloads support 64-bit Windows 10 or 11 and macOS 12 or later. A fully featured trial lasts 30 days; Demo mode then limits resolution and adds a watermark.
