Photographer Graham Riddell believes the Tweed Valley in the Scottish Borders produces some of the most stunning rainbows in the country. He has travelled across the area to capture some striking images of the countryside and skies throughout the region. All pictures by Graham Riddell Photography

The village of Walkerburn is one of the places where a spectacular rainbow has been captured on camera

Mr Riddell says that since moving to the Borders 15 years ago he has been "captivated by the frequency and variety of rainbows" which form in the Tweed Valley

The photographer reckons it has been his privilege to "catch a rainbow or two" like this one over Innerleithen

"There is something unique about this stretch of the Tweed Valley," says Mr Riddell. He captured this rainbow over a ruin at Horsburgh

The "heavy bursts of rain" and "bright dashes of sunshine" experienced in the area make it ripe for rainbows from February until November

When the heavens open over Traquair while there is sufficient sun breaking through it can produce a stunning effect
