|

Reading over simulated bee vision we learn that bees can see uv, and cannot see red - their entire visual spectrum is shifted relative to ours.
There are photos there where the blue channel is discarded, and replaced by the uv one; also, 'bee vision' photos like the above but discarding the red channel. The result, if I understand correctly, is thus two channel, green plus UV:
red -> delete
green -> green
blue -> delete
uv -> blue
However, with that visual range, bees can see blue perfectly well I assume.
I wonder what the results would be like with the following mapping:
red -> delete
green -> red
blue -> green
uv -> blue
in other words, shifting their visible spectrum into ours, while retaining three channels?
But perhaps I have misunderstood how many channels are taken from the uv exposure? _________________ Camera (ˈkæ mə rə), n. Device for taking pictures in bright light
