- The mega pixel of the human eye is about 80 mega pixels but with eye movement, stereo vision, and brain processing the human eye produces about 500 mega pixels. The mega pixel of the human eye is difficult to calculate because the eye moves almost constantly and this helps calculate the image. Also, the visual acuity is much greater directly in the middle of what we see (try reading a sign that you are not looking directly at!) The eye resembles a video camera more then a photographic camera. However, the eye has many similarities to a digital camera, and these similarities help to understand photographic concepts.
- These are estimates only and given to help understand the advantages and handicaps of digital cameras, and to help explain the difference between what we see and what ends up in our photographs. This is explained and developed in other pages. The important thing is to understand the concepts.
- The Dynamic Range is the range of light that can be seen or recorded, and the subtle shades of light within these ranges. So the human eye is still much more sensitive and superior to digital photography, about 20 times more.
