Bracketfuse: HDR Merge

Merge bracketed exposures into one natural-looking photo — with detail in both the bright window and the dark corner.

Pick 3, 5 or 7 photos of the same scene shot at different exposures (camera RAW, DNG, JPEG, HEIC or TIFF). Bracketfuse finds the brackets for you, lines the frames up and blends the best-exposed parts of each one into a single image. Everything happens on your device.

• AUTO-GROUPING — select a whole shoot at once. Brackets are grouped from each photo's exposure data and capture time, and back-to-back sets are split where the exposures repeat. Tick or untick frames to fix a set.
• HAND-HELD ALIGNMENT — frames are registered to the middle exposure before merging, so hand-held brackets stay sharp.
• EXPOSURE FUSION — a multi-scale blend that takes contrast, colour and good exposure from every frame. Natural by default, with no halo-heavy "HDR look".
• REDUCE GHOSTING — people, leaves or water that moved between shots come from one frame instead of appearing see-through.
• LOOK — Natural ↔ Vivid strength, Highlights and Shadows sliders, and white balance matched to the middle exposure.
• CAMERA RAW — raw files are developed with identical neutral settings, so only the exposure differs between frames.
• SEE IT FIRST — the full merged preview with every option, plus a compare view against the middle exposure.
• EXPORT — HEIC, JPEG or 16-bit TIFF at full resolution, keeping the reference frame's EXIF (camera, lens, date, location).

Bracketfuse merges brackets you have already shot, with your camera's auto-exposure bracketing (AEB) or a bracketing camera app — it doesn't take photos. On devices with less memory, very large files are saved at the largest size the device can handle, and the result screen tells you when that happens.

Merging and the full preview are included; a one-time purchase unlocks exporting the full-resolution photo.
