Answer 5

The lower the t-stop number, the shallower the depth of field.

Question 6

How does a low t-stop affect light?

Answer 6

low t-stops means more light enters the camera whereas a high t-stops means less light enters the camera.

Question 7

The amount of light let into the aperture is measured in…

Answer 7

• T-Stops / F-Stops.

Question 8

How do you minimise noise on a higher ISO?

Answer 8

• You use a camera with a higher dynamic range.
