I saw a B&W photo of these stones over on 500px.com the other day and it occurred to me that while I was never really happy with how my photos there turned out, I never tried them in B&W. The colour version always seemed uninteresting, but with some dodging & burning the monochrome has a lot more impact.
Perhaps I need a note next to my monitor that says: “Did you remember to try that in B&W?”
