Capture a photorealistic portrait of a man, facing forward yet slightly in profile, against a vibrant deep blue backdrop. The blue lighting accentuates his facial contours and hair, creating an intriguing interplay of light and shadow. This image mirrors the bold simplicity of a color field painting, with the subject rendered in a deep blue that sharply contrasts the monochrome surroundings. Use a camera setup mimicking a large aperture, such as f/1.4, to achieve a shallow depth of field, focusing solely on the silhouette's edge. A hint of ethereal glow surrounds the subject, enhancing the visual depth, and the composition is detailed in UHD, maintaining an air of raw authenticity while infused with an artistic stylization.
