Clouds were low. Temperature was low. River was low.
Camera was low too.
Scrambled down the muddy river bank on to some normally submerged rocks and set up the camera on a gorillapod with an eight stop neutral density filter screwed on to an old Minolta 50mm lens. Thirty second exposure at f/16 smoothed off the Forth nicely. Really like the results that comes off of that combination.
Only nearly fell in once.
