00:00:00,215 --> 00:00:06,085
So the last way to adjust the exposure of the image is through the aperture right in the barn doors

2
00:00:06,085 --> 00:00:08,835
leading in the light photon counts so the lower the number. The cow things got

3
00:00:08,835 --> 00:00:22,045
the lower the number the wider the aperture the more light is entering the image now this affects the exposure

4
00:00:22,045 --> 00:00:26,277
and it also affects the depth of field which we'll talk about in a minute.
