Tools · Exposure Triangle

Forget the Triangle. Master the Method.

The classic exposure triangle is dead. Robert Morrissey's proprietary EXP=SDQC method reframes exposure as four independent variables — Sensitivity (ISO), Duration (Shutter Speed), Quantity (Aperture), and Color (White Balance). Adjust each below and watch the equation — and your understanding — evolve in real time.
