This is the best shot I have ever taken of a rainbow.
Even though one cannot see much of the arch I hope that you can get a sense of it !
I was driving along the Devil's Dyke Road and spotted this rainbow and just happened to be by a car park, so pulled in and took a few shots hand held.
Setting up the tripod the opportunity would have been missed.
The " S " curve road is the A27, Brighton by pass at the A23 junction. The rainbow appears to be dropping down into one of my favourite spots in the area, , Stanmer Park.
