Noiseless Images
3

Hopefully this won’t turn into the normal sensor size bickering. It is a genuine question with no other agenda other than to understand why our cameras produce noisy images in low light conditions but our eyes never seem to do the same.

Why, when sensor size, aperture size and light levels are so critical to getting low noise images and video, do we not seem to see a world full of image noise when using just our eyes? Our eyes have a relatively small sensor area (the retina - which is probably similar in area to a FF sensor), a small ‘aperture’ (pupil) and a small overall imaging unit size (the eyeball).

Surely if our eyes can appear to perform ‘noiselessly’ in low light then the technology for other small imaging units to do the same is already available.
