A free exposure triangle simulator for photography students. Change aperture, shutter speed and ISO and watch the scene react: depth of field, motion blur, noise and brightness. Press the shutter, hear it fire and complete the challenges.

Each click on a dial is one stop: it doubles or halves the light.

Photos you take appear here with their settings.
The opening inside the lens, written as an f-number. A smaller number means a wider opening: more light and a shallower depth of field. Going from f/2.8 to f/4 halves the light.
Portraits: f/1.4 to f/2.8. Landscapes: f/8 to f/11.
How long the sensor collects light. Doubling the time doubles the light and doubles the motion blur.
Handheld: at least 1/focal length, e.g. 1/50 s on a 50mm lens. Sport: 1/1000 s or faster.
How much the sensor signal is amplified. Each doubling adds one stop of brightness, and more visible noise.
Stay at ISO 100 to 200. Raise it only when aperture and shutter can't give you enough light.
In bright sun, set f/16 and a shutter speed close to 1/ISO. At ISO 100 that is about 1/100 s. Every other setting is a trade from there.
Can't get a soft background in full sun? Photographers use an ND filter to cut the light.
What you can do with Exposure Triangle Simulator.
Aperture, shutter speed and ISO in real full stops.
Depth of field, motion blur, noise and brightness update instantly.
Read exposure the way a real camera shows it.
Manual, aperture priority and shutter priority.
Shoot a frozen car, a soft background or a night scene.
A real shutter sound with every photo.
Get started in a few steps.
Practical benefits for students and designers.
Understand settings before you buy or borrow equipment.
Every change in one setting forces a change in another.
Practise night, sport and portrait settings risk-free.
Move to manual mode on a real camera with confidence.
Made for learners and working designers.
The ideas behind the simulator, in brief.
The f-number controls how wide the lens opens. Lower numbers let in more light and blur the background.
How long the sensor is exposed. Fast speeds freeze motion and slow speeds blur it.
Sensor sensitivity. Higher ISO brightens the image but adds noise.
Each full stop doubles or halves the light. Trading one stop between settings keeps the same exposure.

It is the relationship between aperture, shutter speed and ISO, which together decide how bright a photo is and how it looks.
Yes. It is free and works on phone and desktop browsers.
Yes. Settings follow real full-stop EV maths, while the scene itself is simulated.
Use a wide aperture such as f/1.4 to f/2.8, and get closer to your subject.
In bright sun, use f/16 and a shutter speed close to 1/ISO for a correct exposure.
