Raided Amazon for a new ND filter on Friday and it arrived yesterday! Super quick delivery which I decided against paying for so I was pretty happy to get it through the door next day.
First outing for the new filter was to the bridge at Den of Fowlis aka Spinky Den. It was painted by famous Dundee artist James McIntosh Patrick back in 1957, these days you can hardly see the water through the trees and bushes. Might need to make a return trip later in the year when the water is moving a bit quicker.
