Same exposure · time-domain stacking · 16-bit linear ProPhoto · fully local. Seven presets cover seven burst scenarios, all pixel-wise statistical merges: long-exposure noise reduction (with a √N report), removing passers-by, rain and snow removal, light trails. Sequences are grouped automatically from EXIF by matching exposure and time adjacency, with four alignment tiers — features, sub-pixel refinement and an optical-flow fallback.
There is also sensor dust cleanup with a repair brush, frame import from mp4/webm, and batch “take K of every N” long-exposure delays. Export TIFF16/PNG16 with embedded ICC, bulk-export a whole group as 16-bit TIFF, or write a layered 16-bit PSD. Photos are never uploaded.
