The Camera Versus the Human Eye

How does the human eye compare to a DSLR? If you had to quantify it, it would be a 130MP camera, with a f/3.2-f/3.5 43mm lens, with around 10-14 stops of dynamic range.

“The advantages of the human eye compared to the camera get reduced a bit as we leave the retina and travel back toward the brain. The camera sends every pixel’s data from the sensor to a computer chip for processing into an image. The eye has 130 million sensors in the retina, but the optic nerve that carries those sensors’ signals to the brain has only 1.2 million fibers, so less than 10% of the retina’s data is passed on to the brain at any given instant. (Partly this is because the chemical light sensors in the retina take a while to ‘recharge’ after being stimulated. Partly because the brain couldn’t process that much information anyway.)”
