River Portrait Among Mountain Rapids.

Fresh, natural vertical mountain travel portrait of a young man in his early 20s with thick, voluminous, textured black hair swept up and back, strong dark eyebrows, a full, neatly trimmed dark beard with a mustache, and a calm, serious gaze straight into the camera. He stands upright and centered with his hands behind his back. He wears a light grey and white vertically striped cotton button-up shirt with a chest pocket, the collar open and the sleeves rolled to the forearms. Behind him, a wide turquoise-green glacial river flows over pale pebbly banks, with a blue inflatable rafting boat and a few rafters in helmets and life jackets visible at the lower right. Dense dark-green pine and fir forests cover the steep hillsides rising behind the river, with a grassy slope and a small white pole at the left. The sky is a soft, flat grey overcast. Soft diffused natural daylight, muted evergreen, teal and grey palette with a pop of bright blue from the raft and warm skin tones, slightly desaturated, shallow depth of field, riverside adventure travel lifestyle photography, 35mm lens, ultra-detailed skin, hair, fabric and foliage texture, high resolution, 9:16 aspect ratio. Insert discreet watermark in the lower right corner of the image, vertical text (rotated 90°), written "aipromptlabs.online", Calibri Light font, white color with low opacity (semi-transparent), medium size. Extreme sharpness on the face, fabric texture and typography of the letters. Shot on Canon EOS R5, 50mm f/2.8, studio light.
