We had a chance to do some “milky waves” photography at the coast of Tanah Lot. Many photographers achieve this effect with use of 10-stop ND filters. For us, we just used the waning light of dusk to achieve the long exposure times we wanted. I have converted the monochromatic blue glow of the original to the sepia-toned, high contrast version above.
