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.
