Ultra-realistic portrait of a man in his 40s. He has brown hair with a few white

Ultra-realistic portrait of a man in his 40s. He has brown hair with a few white strands, a neatly trimmed beard and green eyes that reflect surprise and emotion. His face is well defined and his expression suggests discovery and introspection. The portrait should be from the waist up. He is wearing a casual shirt. The man is in a bedroom, holding an open diary. The environment should include elements such as a closet and a bed in the background, but blurred so as not to distract from the main subject. The lighting should be soft and natural, with daylight coming in through the window, creating subtle shadows that accentuate the man's surprised expression. The light should highlight the green eyes and the texture of the skin, emphasizing the seriousness of the situation. The image should convey a sense of discovery and introspection, with a touch of emotion. Suggest a neutral color palette, such as greys and blues, that complements the atmosphere of the room. The photo should be of high quality, with 8k rendering and extreme detail, capturing the emotional essence of the moment.
