Camera Aperture
The aperture is different from the Shutter.
The aperture is the pinhole size of the camera.
Aperture controls the depth of field.
- Ahh, so it’s just a bigger pinhole, which is why things are blurry
What about our eyes?
Do we vary the pinhole size to control the focus? Do our eyes have a fixed pinhole size?
“The eye’s pupil serves as the adjustable “pinhole” through which light enters the eye and falls on the retina.”
Why is brightness constant for us?
The perception of constant brightness despite varying light conditions is due to the eye’s adaptive mechanisms such as pupil dilation/constriction, photoreceptor adaptation, and neural processing in the visual system.
- This is fascinating, it’s a very complex system that we have
