I'm sticking with 1/160 of a second (or faster) whenever I go out photographing in Lewes Railway Land. Today I added another aspect, I shot everything at F4.
Of course I had to be careful, with F4 at 125-200mm it's very easy to get the wrong thing in focus but when it works, it's beautiful.
A downy bee, teazles that stand out like razors against the dark of the wood and a butterfly in the midst of swathes of deep, rich colour. Nothing added, or taken away, in Photoshop.
Worth a try.
