HOW I GOT THE SHOT: Rainbows are rare, unique,
compelling, and, as we are reminded by this week’s Torah portion, a symbol of
both the flood and God’s promise not to destroy the world again. During the
rainy season, I am often propelled from couch to car, chasing these fleeting
phenomena over hill and dale while flirting with cardiac arrest. Occasionally I
succeed and in the category of “expect it when you least expect it,” I present
this image which appeared while I stood on a hilltop in the Judean Mountains
preparing for a family to arrive for a portrait session.
Rainbows are rare because several simultaneous conditions are
necessary for their appearance. The sun must be low on the horizon (below 42
degrees), which is why rainbows are only visible in the morning or late afternoon.
There must also be both precipitation and open sky to allow sun beams to shine
through the cloud cover and pass through the raindrops and refract into the
colors visible in the rainbow.

all the photography buffs in your life.
My elevated perspective allowed me to see and capture the entire
arc of this rainbow, actually a double rainbow, and if you look carefully, you
will notice the color pattern is reversed on the upper arc. The second rainbow
is caused by a double reflection of light inside the moisture droplets.
Rainbows always appear opposite the sun, with a well-lit foreground culminating
in the sky show. They are indeed rare, but rarely are they disappointing.
