What is the T-Stop?

The t-stop is a number that represents the absolute amount of light that reaches the sensor plane.

The Difference Between T-Stop and F-Stop

These two numbers are related, and understanding the difference requires a good understanding of the f-stop. I have written an entire article explaining the f-stop for your reference. Continue reading “T-stop”

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. Continue reading “Exposure Triangle”
