"It was about 8:00
in the morning, and 8 deg. Celsius after clear cold night. In the
sunlight, moisture was evaporating from a pile of damp wood and then
condensing again to rise like smoke."
The curls of condensed droplets diffracted the morning sunlight to
give glowing skeins of
was dificult to take the pictures because of the need to look
through the vapor almost directly into the sun, and at the same
time keep the camera in the shadow and look for a dark background."
But it was well worth it! Optical effects can be found in the most
mundane surroundings. Search for them.
