Some of the night fog was still present, but the sun behind me was very bright.
Here's how Andy Young Green Flash
explains the picture:
"These are essentially crepuscular rays, formed in the remaining fog by
the light reflected from the windows of the building. Somebody referred
me to a similar picture about a year ago -- it might even have been the
same building.
The fog droplets are fairly large, so they're strongly forward-scattering.
That limits the angular length of the rays, which don't extend very
far from the image of the Sun formed behind each window. That makes
these really *crepuscular* rather than anti-crepuscular rays; they're
seen in the anti-solar direction because that's where the light source
(the reflection of the Sun in a window) is.
It's quite a pretty effect, isn't it" |
