Bob,
You have some very nice images on your web site.
This group has been a little sluggish lately, but for those
still around, there are many very knowledgeable people who will help
in many ways.  There are currently no trolls in this group;
just helpful people.  But since it is a little sluggish,
it might be a while for answers to come forth.  This group
is great on photography questions, equipment related to the group,
and locations (the world over), including current status of conditions
(for those members living in certain locations, or who
have recently visited the area).
