Exposure Simulator

Note
The exposure portion of this simulator currently does NOT work with Internet Explorer. Please use Chrome or Firefox instead.
Overview
This tool attempts to roughly simulate a final photograph given a particular set of camera settings. The simulation includes:
- Demonstrating depth‑of‑field based on the current f‑stop.
- Showing image “noise” or “grain” that is introduced as you increase the ISO.
Future updates may include new previews (e.g., using a small fan) to demonstrate how shutter speed affects moving objects.
Shooting Modes
Three shooting modes are available:
- Shutter Priority (Tv) – you control the shutter speed and the camera auto‑calculates the appropriate aperture.
- Aperture Priority (Av) – you control the f/stop and the camera auto‑calculates the appropriate shutter speed.
- Manual – you have full control over both shutter speed and aperture.
Camera Setting Sliders
Use the sliders to set the three primary variables that control a photograph’s exposure:
- Shutter Speed
- F/Stop
- ISO
Exposure Meter
A camera meter is located above the simulated picture. It mimics what you see inside your DSLR’s viewfinder and indicates whether the current exposure is underexposed or overexposed by up to three stops (or more if the arrow begins to blink).
