A rugged old sailor around fifty years old, face occupying 70% of the frame, fully shown from brow to chin, with wet dark gray wool brim and heavy sealskin collar on both sides of the face. Skin weathered by sea wind into dark reddish-brown, nose tip and cheekbones frozen red, face has salt frost, freckles, fine wrinkles and wind cracks. Dense gray-white beard wet and tangled, with ice crystals and salt grains hanging at the ends of the beard, water droplets forming needle-point reflections under cold light. His eyes are light blue-gray, whites of eyes reddened, gaze looking to the lower right of the camera, tired and alert. On the lower left, ice and sea water reflect cold white light, illuminating the chin, beard and lower edge of the nose bridge; the upper face sinks into blue-gray shadow, forming an abnormal lower cold light cut. Background is blurred black sea, gray-white sea fog and horizontal wind and snow, no ship details. Colors are blue-gray, cold white, deep sea black, low-saturation brown-red skin and gray-white beard. Overall low brightness, vignetting 20%, film grain 15%, skin and beard sharp, background fogged.
