A realistic photograph taken with a Canon 5D, showing a friendly installer in a modern apartment, holding his smartphone with the screen clearly visible, displaying a progress update or confirmation. A delighted woman stands slightly to the side, observing attentively, her hands relaxed by her sides and a warm, engaged expression on her face, as she listens closely to the installer. The installer wears casual work attire, and natural light from a nearby window illuminates them, casting a soft, inviting glow. The apartment has a cozy, modern decor with subtle elements in the background. Shot with a shallow depth of field, focusing on the installer, the phone screen, and the attentive expression of the woman for a professional, realistic effect.
