Lecture 15: Cameras & Lenses (44)

Is there a special unit for exposure, or is it just time * irradiance?


I am also wondering why the exposure is not an integral of irradiance over time but simply a product?


I also think it would be an integral since irradiance can vary over time but perhaps it is just being simplified to TxE here just because it is the first time it is being introduced.
