Slay, the Composition-Guide Camera

Field notes

Slay presents composition as a live alignment workflow rather than a rule to remember afterward. Its guide library spans conventional devices such as rule-of-thirds framing alongside named perspective systems including One-Point Vertex, Two-Point Vertex, and Aerial Triangle. The page also lists 0.5–3x native zoom and describes each guide as carrying its own step-by-step instructions. The homepage does not identify supported phone models, so compatibility cannot be determined from the available material.
