CKAN vs FocusFusion

CKAN helps Kerbal Space Program players find, install, and manage mods through a client connected to an online registry. Users can refresh the registry and search by mod name, identifier, author, or relationships. CKAN uses mod metadata to select mods for the game version, install dependencies, and identify conflicts or incompatibilities. By default, a mod must be marked compatible with the exact game version; users can choose additional compatible versions, and an All filter can display incompatible mods. The client provides graphical, console, and command-line interfaces. It runs on Windows, macOS, and Linux, with installation options for several Linux distributions. The executable can manage game installations from any folder; placing it in a game folder supports portable use. Mod authors can contribute or correct metadata. CKAN is open source and MIT-licensed, and is free. On macOS 10.15 and later, the console interface is the default because the graphical interface depends on a 32-bit WinForms application in Mono.

FocusFusion is a free Windows application that combines photographs taken at different focus distances into one image with greater depth of field. It provides depthmap and wavelet focus-stacking algorithms, automatic alignment, and manual retouching. Depthmap expects images ordered front-to-back or back-to-front and can struggle with translucency or complex overlaps. Wavelet accepts images in any order, but may increase noise, create artifacts at sharp luminance transitions, or reduce alignment quality. Processing uses at least 16-bit precision per channel. Supported inputs are TIFF up to 48 bpp, 16-bit-per-channel JPEG XR, and classic 8-bit JPEG; RAW files are not supported. A clone-based retouching tool offers adjustable brush size, hardness, and opacity, with cloning at 16-bit quality. FocusFusion requires Windows 10, an SSE4.1 CPU made after 2008, and at least 8 GB of memory; 16 GB is recommended for deeper stacks or larger DSLR images. It is distributed through the Windows Store.
