Dynamic Symmetry
Composition on root rectangles and their reciprocal diagonals rather than on thirds.
What it does
Jay Hambidge's 1920 system builds a rectangle from a root proportion, then draws the diagonal and a reciprocal perpendicular to it; where they cross are the compositional anchors. George Bellows and Robert Henri used it, and Hollywood cinematographers still refer to it. It differs from the rule of thirds by being derived from the frame's own proportion, so a 4:3 and a 16:9 frame give different anchor points rather than the same lazy nine-square.
The prompt
Replace [Subject] with what you are shooting. Everything else is deliberate: the gear, stock and lighting are what push a generator towards this look.
