That's about right - there's a narrow blue edge line produced on the 
edge of the fisheye circle in areas next to blue sky on sunny day 
shots. A thin edge line, not a typical flare effect or the internal 
reflections on that Peleng shot. Seems to be part of the deal which is 
why I posted that Photoshop query about how to do a neat soft edge 
circular mask as a way of losing the less pleasant edge effect. Not an 
issue with B&W but as soon as you go to slide...
as if fishing wasn't tough enough.
