Zuiks;
Copied below is eMail I received off-list, and my response. I think
John has helped me understand much of the reason the barrel distortion
was so pronounced on this photo, but is not present in my others.
Anyone else (Gary Reese?) care to comment on this?
Thanks
george

John!
You may very well be correct. I hadn't thought of this, but it makes
sense. I looked again at some similar slides I took another evening:
ocean sunset, horizon at about same part of frame. Difference? In
these, the horizon is perfectly straight and, I was sitting comfortably
on the beach with the tripod in front of my chair. (Hey, honey, another
Corona, por favor).
In the photo with the barrel distortion, I was on the deck of a hotel,
about 10-15 feet above the water, so the camera *was* aimed down a bit
to get the rocky foreground. I think you've id'd an easy way to avoid
the problem.
