Exposure Simulator

Adjust shutter speed and aperture to see how they change exposure — ISO is locked at 100, so the chart below shows EV₁₀₀.

Current Exposure Value (EV₁₀₀)

The picture is a real photo of the same scene captured at each exposure value. As you change shutter speed or f-stop, it updates to the frame matching the current EV₁₀₀ — so any settings that land on the same EV (equivalent exposures) look identical, while a higher EV gets darker and a lower EV brighter.

Three shooting modes:

Shutter Priority (Tv) — you set shutter speed; the camera picks the f-stop.
Aperture Priority (Av) — you set the f-stop; the camera picks shutter speed.
Manual (M) — you control both.

ISO is fixed at 100. The chart highlights the EV₁₀₀ for your current shutter × f-stop combination, where EV = log₂(N²÷t).
