Facts

Purpose
HDRMerge creates raw images with extended dynamic range by merging exposure-bracketed raw files or multiple exposure-bracketed frames in a single raw file.jcelaya.github.io · 2 Oct 2026
Output
It outputs DNG 1.4 images with floating-point data, using less noisy input pixels to preserve shadow detail.jcelaya.github.io · 2 Oct 2026
Ghost removal
Its graphical interface lets users edit the merge mask to remove ghosts caused by moving objects between exposures.jcelaya.github.io · 2 Oct 2026
Alignment and cropping
HDRMerge can align small translations and crop output to the area shared by the input raw images.jcelaya.github.io · 2 Oct 2026

Integrations
