This evening we stepped away from our viewfinders to examine the most sophisticated piece of visual equipment we have: the human eye.
As photographers, we spend our lives obsessed with light, glass, and sensors. However, this fascinating session reminded us that the final image doesn’t happen inside a Nikon or a Canon—it happens in the mind.
The talk began with a deep dive into the biological “hardware.” We explored the intricate anatomy of the eye, from the protective cornea and the light-regulating iris to the lens and the retina. Understanding how these parts function isn’t just for biologists; it’s a masterclass in optics. We explored the direct parallels (and the startling differences) between our eyes and our cameras. While we often think of our eyes as “living cameras,” but the way our brains detect and process light is far more complex than any digital sensor currently available.
The talk then shifted to a broader perspective, looking at the animal kingdom.
Perhaps most interesting was the discussion on colour vision. Did you know that most mammals actually lack full colour vision? We explored:
-
The evolutionary “why” behind our ability to see a full spectrum.
-
How colour vision provided an edge for our ancestors.
-
The trade-offs nature makes between low-light sensitivity and colour detail.
