Exposure Lab is a working camera you can learn on, in the browser. It is three tools behind one door: a photography lab built on photorealistic plates, a cinematography monitor that grades 25 photorealistic scene loops through the actual physics of a cine camera, and Light Lab, a portrait lighting studio where a photorealistic face exists as sixteen separately lit exposures, so every shadow you make was lit, not painted on. Light Lab is currently in Beta.
The imagery is photorealistic and the physics is real. Exposure is metered in stops. Depth of field comes from the lens equation. Shutter angle smears motion the way a rotary shutter does. When you halve a lamp's distance in Light Lab, the near cheek takes four times the light, because that is what light does.
It exists because cameras and lights are expensive, and the understanding is not. A few minutes with a needle that moves when you open a stop teach more than a chapter about the exposure triangle. The tool is made for students, self-taught shooters, and anyone standing in front of their first set wondering which knob matters.
Exposure Lab is an independent product, and an openly modern one: the code was written with AI, the imagery is AI-generated and photorealistic, and the physics underneath is checked against how cameras and lights really behave. When you write in, a person reads it. Say hello at [email protected].
