A truth that’s told with bad intentBeats all the lies you can invent.
– William Blake
Victor Hugo and Leonardo DaVinci were two among many who were very interested in chance images. These are images that appear to the eye when staring at such things as dirty walls or clouds or ashes. Images come up out of the mind – or out of where? DaVinci had his answer: from the mind of the beholder, he thought, and they were a rich source of subject matter, he said. But how does such imagining happen, staring into images or ashes or folds of a curtain, happen? Read more about the history of “chance images” on this site here.
Sundogs are made commonly of plate-shaped hexagonal ice crystals in high and cold cirrus clouds or, during very cold weather, by ice crystals called diamond dust drifting in the air at low levels. These crystals act as prisms, bending the light rays passing through them with a minimum deflection of 22.° . . . [O]ften, as the crystals sink through the air they become vertically aligned, so sunlight is refracted horizontally — in this case, sundogs are seen.
I have several sundog photos. The tan sky was really blue, but the experimentation with light created the shift to tan.
