Adjustable blending

Command-line options let users adjust the relative weights for exposure, saturation, and contrast.Read 8 Oct 2026 · hugin.sourceforge.io

Algorithm

It merges overlapping images using the Mertens-Kautz-Van-Reeth exposure fusion algorithm.Read 8 Oct 2026 · hugin.sourceforge.io

Alpha channel

Input images can use zero-valued alpha pixels to exclude those pixels from blending.Read 8 Oct 2026 · hugin.sourceforge.io

Alpha channels

Input images can use alpha values of zero to exclude pixels from blending; without an alpha channel, Enfuse processes all pixels.Read 8 Oct 2026 · hugin.sourceforge.io

Blending criteria

It evaluates pixels by exposure, saturation, and contrast, with command-line weights to adjust each criterion.Read 8 Oct 2026 · hugin.sourceforge.io

Distribution

The Enblend project page lists Linux and Windows, and its files page offers an Enblend-Enfuse 4.2 Windows 64-bit archive.Read 8 Oct 2026 · sourceforge.net

Exposure fusion

It weights pixels using exposure, saturation, and contrast criteria to produce the blended image.Read 8 Oct 2026 · hugin.sourceforge.io

Focus stacking

Enfuse can blend a focus stack to build images with extended depth of field.Read 8 Oct 2026 · hugin.sourceforge.io

Focus stacks

Enfuse can blend a focus stack to build images with extended depth of field.Read 8 Oct 2026 · hugin.sourceforge.io

Image cache

The manual gives a default image cache size of 1024 MB and describes moving image data between memory and disk.Read 8 Oct 2026 · hugin.sourceforge.io

Integration

The Hugin site says Hugin uses Enfuse for exposure fusion of bracketed stacks.Read 8 Oct 2026 · hugin.sourceforge.io

Known limitation

The documentation notes that contrasty structures near the zenith or nadir of an equirectangular image can produce a vortex artifact.Read 8 Oct 2026 · hugin.sourceforge.io
