-
Composition Analyzer
Overlay thirds, golden section, rabatment, the harmonic armature, dynamic symmetry, and the golden spiral on any photograph. The frame is read from the image itself. Images stay in your browser.
-
Contact Sheet
Review a set of frames the way editors do: mark selects, maybes, and rejects, then study composition across the whole take.
-
Depth of Field
See how sensor, focal length, aperture, and focus distance shape the sharp zone — and where the hyperfocal distance sits.
-
Attention Heatmap
A simulation of where the eye is likely to land first in your photograph, based on brightness, contrast, and edge structure.
