Question 1

What are t-stops and f-stops, and what is the difference between them?

Answer 1

T-stops and f-stops are both measures of the amount of light that a lens allows to pass through to the film or image sensor, but T-stops take into account any loss of light due to lens elements and other factors, while f-stops are a measure of the size of the aperture.

Question 2

What is a stop?

Answer 2

A measure of light. One stop means doubled or halved. 1 stop up, means doubled. 1 stop down means cut in half.

2 stops of light up means four times the amount of light (double then double again) and 3 stops of light down means 1/8th the light (cut in half, then half again, then half for a third time).
