Exposure Triangle Calculator – Calculate ISO, Aperture and Shutter Speed for Photography
Exposure triangle calculator helps photographers find the right exposure settings by calculating the relationship between ISO, aperture (f-stop), and shutter speed. Change one setting and see how the others must be adjusted to maintain consistent exposure.
The tool displays the exposure value (EV) and calculates equivalent settings when one variable changes. Perfect for both beginner photographers learning the exposure triangle and experienced ones who need quick calculation assistance in the field.
What does the exposure triangle mean in photography?
The exposure triangle consists of three factors: ISO (sensor sensitivity to light), aperture (f-stop, lens opening size), and shutter speed (how long the sensor is exposed to light). The balance of these three determines image brightness. Doubling ISO, opening the aperture one stop, or halving shutter speed each double the amount of light reaching the sensor.

Adjust one part of the exposure triangle (aperture, shutter speed, or ISO), and the calculator shows corresponding values for the others.
- Calculate correct exposure settings by changing one of three variables.
- See equivalent exposures with different setting combinations (EV values).
- Understand how aperture, shutter speed, and ISO affect each other.
The exposure triangle describes the amount of light – the same exposure can be achieved with many different combinations.
- Wide aperture (low f-number) = more light + shallow depth of field.
- Long shutter speed = more light + motion blur.
- High ISO = more sensitivity + more noise.
The exposure triangle is a fundamental photography concept – mastering it opens creative possibilities.
- Different situations require different priorities: fast shutter speed for sports, wide aperture for portraits.
- The camera's light meter and histogram help fine-tune exposure.
- The calculator is an educational tool – field practice is the best teacher.
