Found this interesting article about the human eye:
Red rose at twilight: In bright light, the color-sensitive cones are predominant and we see a brilliant red rose with somewhat more subdued green leaves. But at twilight, the less-sensitive cones begin to shut down for the night, and most of the vision comes from the rods. The rods pick up the green from the leaves much more strongly than the red from the petals, so the green leaves become brighter than the red petals!
This is making me think about when shooting in that if it were twilight conditions and you wanted to shoot something like a rose, would the camera be able to compensate agaist the judgement of your actual eyes to produce a brighter red?
I wonder how many great photo opportunities are missed due to human error in a physical vision shortfall such as this where a camera may be able to compensate electronically?
Taking it even further, if you are shooting or editing photos would your vision with regard to camera settings and also colour calibration on the computer that you are editing on change as it becomes later in the night and the cones begin to shut-down?
The source of article is Here (http://hyperphysics.phy-astr.gsu.edu/hbase/vision/rodcone.html) and I am bored on this Friday afternoon! :whistling:
