Full Fog Bow
Shot soon after the earlier posting of a barn with rising rainbow created from the fog. The sun was at the right angle here to provide a full refracted "Fog Rainbow". These were primarily just bands of light thrown up from the fog, but they did have very faint color bands near the base. I've been calling them "Fog Rainbows", but if there is an alternate name for them please let me know. Very interesting phenomenon.
I shot in this area for three mornings with fog in the area each morning, but this was the only day that there weren't clouds to the east that blocked the direct illumination from the rising sun. On the other two days the fog exhibited only as "normal" fog.
Since the original posting I have done more research on these and the official term is a "Fog Bow".
