A 4K ultra-detailed, high-resolution indoor studio shot of an elegant wristwatch lying flat on a luxurious white marble surface with subtle veins. Captured using a Canon EOS 5D Mark IV with a 50mm f/1.2 lens, the aperture is set to f/2.2 to keep the watch in sharp focus while creating a soft bokeh effect for the marble background. The watch features a sleek metallic body, polished bezel, and a leather strap, with the face showing intricate details of the hands and markers. Soft diffused light from a large softbox is used to gently highlight the metallic sheen of the watch, while a subtle side light adds depth and shadow to emphasize its texture. Photoshop techniques are applied to enhance the reflection on the watch face, remove any unwanted glare, and refine the marble surface to keep the background clean and elegant. This composition is perfect for a luxury watch advertisement, conveying a sense of sophistication and timelessness.
