each detecting photons from one small point in space.

Meanwhile, the night is also buzzing with insects,such as hawk moths which can see their favorite flowers in color, even on a starlit night.They achieve this by a surprising move -getting rid of details in their visual perception.Information from neighboring photoreceptors is grouped in their brains,so the photon catch of each group is higher compared to individual receptors.However, grouping photoreceptors loses details in the image,as fine details require a fine grid of photoreceptors,each detecting photons from one small point in space.
