A realistic photograph taken with a Canon 5D, capturing a 45-year-old installer in a bright, modern apartment, holding his smartphone and showing the screen to a 30-year-old woman. The screen is clearly visible, displaying an installation update or confirmation, while the installer explains its details. The woman stands slightly to the side, listening with a warm, attentive smile, focused on the information. Natural sunlight fills the apartment through large windows, creating a bright and inviting atmosphere. The apartment has a modern, clean design with subtle decor elements in the background. Shot with a shallow depth of field to emphasize the installer, the smartphone screen, and the woman’s engaged expression, achieving a realistic and professional look.
