A realistic photograph taken with a Canon 5D, featuring a friendly installer in a modern apartment, holding his smartphone so that the screen is clearly visible. The screen displays a completed installation confirmation or a progress report. A delighted woman stands beside him, smiling and looking at the phone screen with appreciation. The installer wears casual work attire, and both are illuminated by soft, natural light coming through a nearby window, giving the scene a warm, welcoming atmosphere. The background shows a modern, cozy apartment interior with subtle decor elements. Shallow depth of field focuses on the installer, woman, and phone screen, for a professional, engaging look.
