That is a superb photo. I would never have thought that pylons could
add to a scene but they do in this case and very well too.


Thanks Jack... it was the only place I could safely stop where I could see
the whole thing. I think my caption says it all, nature applying a temporary
paintbrush to the landscape!


A little experiment worth trying next time there's a rainbow. Look at
it through a polarising filter (or polarised sunglasses) and rotate
the lens. It provides a superb demonstration that the light from a
rainbow is polarised. I have yet to try the experiment with a sundog
(parhelia) or other atmospheric optical phenomena.

I actually did use a circular polarising filter on the lens when taking the
image, and I did indeed have some fun playing around with it (now you see
it, now you don't)!
