Create a high-quality, realistic YouTube thumbnail with a focus on minimalism and the power of emptiness. Place a detailed, photorealistic Apple product, such as an iPhone or MacBook, at the center of the image, slightly offset to one side. The product should be in a crisp, high-resolution close-up, surrounded by a vast, empty white background to emphasize simplicity and elegance. Incorporate a subtle design element, like a simple empty rectangle or a thin line that crosses the image, reinforcing the minimalist aesthetic. The overall composition should convey sophistication, modernity, and a clean, uncluttered look, similar to the style seen in Leo Duff's thumbnails. Ensure the image has plenty of open space, allowing for additional elements to be added later.
