One of the last from the other week whilst out with Mark and Nicky. This is the sort of scene you pray you don't get wrong using the big stopper as the wind was moving the clouds along very quickly, and this was the last of them.
I was very pleased when I saw the back of the camera after guessing it needed a further 30secs on top of the calculated shutter speed!
F16, ISO 200, 135.4 secs, 10mm
Thanks for taking a look
