- How the exposure triangle works
The exposure triangle is the relationship between aperture, shutter speed, and ISO. These three settings work together to control the amount of light that hits your camera’s sensor. Adjusting one setting usually requires compensating with another to maintain the correct exposure. For example, increasing the shutter speed to freeze motion might require widening the aperture or increasing the ISO to let in more light. Balancing the triangle helps you achieve the desired exposure for any lighting condition. - Practical examples of adjusting these settings for different lighting conditions
Imagine shooting outdoors on a sunny day. You might use a fast shutter speed (1/1000s) to freeze action but need to use a low ISO (100) to prevent overexposure. Indoors, with low light, you could use a wider aperture (f/2.8) to let in more light, paired with a slower shutter speed (1/60s) and a higher ISO (800). Experimenting with these settings will help you adapt to varying conditions.
