Really Large Sun Pillar

This is an 90 degree tall image. Almost straight up is top frame. HUGE tall pillar and pretty durn good dynamic range in this capture. To look into the furnace but still be able to make out the landscape ladder is extensive DR. Most cameras would show that as a black silhouette. Try it :).

Sun pillars are shafts of reflected light. Ice reflected spotlights as it were shooting generally 90 degrees up or down to the horizon. This is BY FAR the tallest pillar I’ve ever seen.

I’ve seen them below the sun many times as well. They form on ice crystals in the atmosphere. A combination of many many reflections off the large flat face of horizontally falling plate ice crystals. The effect is very similar to any slightly tilted horizontal surface. For instance, water reflect a light source (usually the sun) and spread it out vertically. This one is REALLY big. This is due to a 12mm lens wide lens.This is not quite 2 times again the subtended angle/width of view afforded by your normal vision at around 55mm would.

The Physics explains it of course but the bigger they are, the rarer they are. The maximum extent of the pillar is about twice the maximum tilt of the plate crystals. Big oriented plates of ice positioned at a high angle are required for this particular phenomena. The crystals are all flat 6 sided plates. These fall the same way/orientation due to atmospheric resistance and their shape. Calm falling air is necessary. The high tilt is unusual. I’ve read sunpillars 5-10 degrees tall is not unusual. (I’d have to look at the meta data and do the math. It certainly seemed big to me at the time (click click click etc ).
