The Exposure Triangle is a key part of photography. It has three important elements: ISO, shutter speed, and aperture. Each one helps control the light in your photos.

1. ISO:

   • This tells you how sensitive your camera's sensor is to light.
   • Common settings for ISO range from 100 to 6400. When you double the ISO (like from 100 to 200), your camera becomes twice as sensitive. This means you can take pictures in lower light without having to wait too long for the camera to take the shot.

2. Shutter Speed:

   • This shows how long the sensor is open to light.
   • Typical speeds can range from really fast, like 1/8000 of a second, to much slower, like 30 seconds. If you make the shutter speed slower (for example, changing from 1/500 to 1/250 seconds), it lets in more light.

3. Aperture:

   • This is about how big the opening in the lens is.
   • It’s measured in f-stops, like f/2.8 to f/16. When you change the f-stop by one full number, it either halves or doubles the amount of light that comes in. For instance, changing from f/4 to f/2.8 lets in about 1.4 times more light.

By understanding how these three parts work together, photographers can get the right amount of light in their pictures and explore their creativity.
