Is this warmtone paper and developer? It has an almost pink/brown look which suits the shot. Once you've been to Dungeness and I have only been about 14 years ago,there's somehow no mistaking it although there are no real clues in the shot. Dungeness shots must have a certain feel which you've captured.
If you are still interested in an answer ..... this image is actually a digital duotone, but the color is in imitation of what I was getting with Iflord Multigrade IV Warmtone FB and selenium toning.
