Cullibrate has five review modes. Each is optimised for a different question you're trying to answer while culling. You can switch between them with keyboard shortcuts G / Z / S / F / T.
Grid (G)
A dense grid of every photo in the shoot. Best for a first pass — sweeping through hundreds or thousands of frames at a glance. Density slider adjusts how many fit per row.
Zoom (Z)
A single photo at 1:1 pixel scale, drawn from the highest-resolution embedded JPEG. Best for checking sharpness on a specific frame.
Survey (S)
Compare candidates side-by-side (2 – 6 at a time). Best for picking the keeper from a burst.
Face survey (F)
Groups similar shots by face and shows the faces zoomed in. Best for catching blinks and closed eyes in group shots.
Filmstrip (T)
One frame large, thumbnails scrolling below. Best for a keyboard-first, one-at-a-time review.
