Fashion Photography: Shutter Speed & Runway Motion Blur

A working fashion-shoot studio in miniature: a model walks a catwalk under strobe lighting while you control the exact three settings a real photographer rides during a show — shutter speed, aperture and ISO. The model's stride is computed as a continuous function of time, so the sim can literally integrate that motion across however long the shutter stays open, freezing sharp, crisp fabric detail at a fast shutter or producing genuine editorial motion blur at a slow one. A live exposure-value readout shows exactly how many stops off "correct" the current combination is, and the background lights render through an instanced bokeh field whose disc size tracks the aperture in real time — wide open for creamy soft backgrounds, stopped down for a crisp one.
