Exposure Triangle

There are three parameters that control how bright an image will be, as shown graphically in image above. This is what is known as the exposure triangle, because all three of these parameters are related: adjust one of them, and the other two must be adjusted to compensate or the image brightness will change. The two parameters at the bottom control how much light reaches the sensor, while the ISO controls how sensitive the sensor is to light read more

Aperture

 

At its most fundamental level, the f-number tells us how much light is reaching the sensor. To be a little more precise, this quantity of light is the intensity per unit area. This will be discussed in greater detail later, but for now read more
