SUMMARY
Human eyes and cameras perceive light differently, with eyes adapting dynamically across over 20 stops while cameras capture a maximum of 13-15 stops per frame. This dynamic range gap is a primary reason for disappointing landscape photos where highlights are blown out or shadows are underexposed. Techniques like exposing to protect highlights, using graduated neutral density filters, and exposure bracketing are workarounds to bridge this difference. Modern sensors have improved shadow detail recovery through dual gain readouts, but the fundamental limitation compared to human vision persists.
TAKEAWAYS
Human eyes adapt across 20+ stops of light, while cameras capture 13-15 stops.
The eye's adaptive range is a real-time process, unlike a camera's single exposure.
Photography techniques like exposing to the right and bracketing compensate for this gap.
Improved sensor technology enhances shadow detail but doesn't fully match human vision.
