This is the third time I've heard of this one. The first was us showing up to shoot, thinking we got our gear wet, then figuring it was from the AC and to dry it out on the dash board before we shot. Then we got a panic call from a friend with the same issue.
Nice to see someone actually made it work out to something beyond fear and trepidation. :) Love the aura of that shot.
I have had this happen to me twice, once on this snot; the first time I was out shooting outside in winter and then entered a tropical conservatory. At the conservatory the lens was essentially opaque with condensation, I had to wait 20 minutes for the lens to warm up and the condensation to evaporate. That time I has a UV lens filter, so the condensation did not happen on the actual lens.
And thank you for your compliment on the photo, serendipity smiled upon me that day.
Cheers,
