A very wet and miserable morning in the Ogwen Valley. Shot from just off the path on the way down from Llyn Idwal.
I used a 10 Stop ND filter to allow for a 80 second exposure time. This helps to show the movement in the think clouds and makes the water in Llyn Ogwen smooth. I processed the image using Nik's Silver Efex Pro to enhance the really 'gritty' textures in the rocks.
