Best Photo Culling Software for Linux

BurstPick is a desktop culling application for wildlife, bird, and action photographers who shoot RAW bursts. It reads a folder of photos, groups frames shot close together into bursts automatically, and scores every frame so the likely keeper rises to the top of each burst. Scoring uses six criteria weighted for wildlife rather than portraits: Focus (28%), Eye Visibility (22%), Exposure (17%), Composition (17%), Noise (11%), and Context (5%). Focus measures sharpness on the detected subject rather than the whole frame; Eye Visibility checks whether the subject's eye is open, lit, and in focus; Noise is ISO-aware, tolerating grain while penalizing banding. Weights are adjustable with live re-ranking, presets can be saved and exported, and a "Calibrate from my picks" tool derives a weighting from frames you have already chosen. A per-criterion breakdown explains every score.

CoolCroco is a free image viewer built for one job: getting through a shoot without waiting. It decodes a whole folder of RAW files on background workers and holds them in memory, so once the first pass is done you move through hundreds of frames instantly, forwards or backwards, with no re-decoding and no cache thrashing. Cull with one key. A files a photograph into an Approved folder, X into Rejected, and Ctrl+Z puts it back. Nothing is ever deleted - files are only moved beside the originals. Rate from 1 to 5, written as XMP where Lightroom, Bridge and Capture One read it. It reads RAW from Sony, Canon, Nikon, Fujifilm, Olympus, Panasonic, Pentax, Leica, Hasselblad and Phase One through LibRaw, plus HEIC, JPEG, PNG, TIFF and WebP, up to 100,000 photographs in one folder. It also finds duplicates and bursts, detects out-of-focus frames, and searches a shoot by what is in the pictures, entirely on your own computer. Windows, macOS and Linux.
