So the last way to adjust the exposure of the image is through the aperture right in the barn doors

0:00:06.085,0:00:08.835
leading in the light photon counts so the lower the number. The cow things got

0:00:08.835,0:00:22.045
the lower the number the wider the aperture the more light is entering the image now this affects the exposure

0:00:22.045,0:00:26.277
and it also affects the depth of field which we'll talk about in a minute.
