Guys and gals,

Please take a look at this rather spectacular picture, which won the AvWeb Picture of the Week competition:

Can someone please explain why everything (sea, sky and rock) is a couple of shades lighter inside the rainbow than it is outside? I'm just curious, that's all....

Is the whole effect the product of a contaminated lens (by accident or design)? I mean, where is the moisture comming from to cause the rainbow?

Stirred a memory from long ago...

..look for the section - "Why is the sky brighter inside a rainbow?"

Saw a complete circle rainbow one day whilst flying. Beautiful to see.

Never seem to be at the right place/weather/sun angle to have seen one again. But still a superb sight.

Eharding - thanks, your link seems to answer the question, and also contains lots of other interesting info!

TD&H - you need to speak to brockenspectre (http://www.pprune.org/forums/member.php?s=&action=getinfo&userid=35129) about that, although she hasn't posted on this forum for a while...

TD&H,

I saw one of those circular rainbows too - a few years ago but have never forgotten it. I was flying from Swansea to Shobdon, and more or less flew through it. Spectacular, isn't it?
