Black and White photo of some beach huts in Carantec, France. Black and White conversion done in Photoshop. I experimented with duotone, tritone and quadtones in this picture, finally deciding on the Photoshop preset ‘BL WmGray 7 WmGray 2’ which is a tritone. I found that this gave the picture a slightly warmer feel to a plain black and white conversion.
