Create a high-quality, realistic YouTube thumbnail with a 16:9 aspect ratio, focusing on minimalism and the power of emptiness. Place a detailed, photorealistic Apple product, such as an iPhone or MacBook, slightly off-center, leaving ample empty white space around it. Ensure the product is in a sharp, high-resolution close-up to emphasize its elegance and simplicity. Incorporate a subtle design element, like a simple empty rectangle or a thin line, to enhance the minimalist aesthetic. Leave substantial empty space at the top and to one side of the image, ensuring there's room for additional text and a photo of a person to be added later. The overall composition should convey sophistication, modernity, and cleanliness, echoing the style of Leo Duff's thumbnails.
