Thanks, Aram!
Just give me a while to make a better series of test images. I'd thought 5
would be enough, but then, it is a first effort.
Unfortunately (or fortunately, depending on how you look at it) we have two
granddaughters arriving in the next day or so, so it may be a few days before I
can do some more test shots. But, I'll be in touch, as soon as I do, via off
list mail.
Thanks, once again, for the offer!
David.
