A realistic photograph taken with a Canon 5D, showing a friendly, 45-year-old installer in a modern apartment, holding his smartphone toward a 30-year-old woman, explaining the details on the screen. The phone screen is visible, displaying an installation update or confirmation. The woman, standing slightly to the side with an attentive, warm smile, listens closely as he explains. The installer wears casual work attire, with a few signs of experience on his face, while the woman’s youthful enthusiasm is evident in her expression. Both are softly illuminated by natural light from a nearby window, giving the scene a cozy, inviting feel. The apartment interior is modern and tasteful, with subtle decor in the background. Captured with a shallow depth of field, focusing on the installer, the phone screen, and the woman’s engaged expression for a professional, realistic atmosphere.
