On a smaller scale, cameraswith appropriate filters can 'see' in the ultraviolet and take photo-graphs of flowers that show an alien range of stripes and spots thatare visible to, and seemingly 'designed' for, insect eyes but whichour unaided eyes can't see at all. Insect eyes have a spectral windowof similar width to ours, but slightly shifted up the burka: they areblind to red and they see further into the ultraviolet than we do -into the 'ultraviolet garden'.*
