Good Evening, Peter!
I'm glad that I'm not the only one seeing this delusion! I suspect you may be
right ... the same thought had crossed my mind. But, enquiring minds want to
KNOW!
Thanks for your kind words about the shots. More good luck than good
management. ;-)
David.
Hiya David. Great shots of something I've seen before, too, with new exterior
wood construction. While I've not had an engineer or chemist spell it out for
me, I always figured that some chemical or chemicals in combination present
in the new treated wood create some form of "soap"when water/rain is present
that would give rise to the short-lived bubbles; and as the wood ages that
chemical or chemicals responsible for the effect dissipate or "off-gas" and
aren't available to create the bubbles when water/rain is introduced.
Best regards,
Peter Stevens

Subject: [LRflex] Tiny bubbles, in the wood....
Good morning, all!
I've spent the last few days repairing/rebuilding the upper deck on my house.
I've replaced the fascia of the decking and the plywood decking itself.
Late yesterday afternoon, I had to stop for the day, as a string of
thunderstorms moved in.
I noticed that the rain formed long-lasting bubbles, with a life of about 10
to 15 seconds,

until another rain drop hit them, and they burst.

But, I was wondering if anyone here can tell me why such bubbles would form,
when they did not form on the old wood.
Just a curiosity....
David.
PS: shots taken with Oly's E-M1 and the 50~200 zoom + 1.4 converter ... so a
540mm eFl. Light, lousy. Exposure, yes.
