Create an enticing image for an Instagram ad for a soft drink, without using any words. The image should evoke a sense of cool refreshment and casual enjoyment. The main subject is a frosty can of the soft drink, held in a hand against a blurred background of a lively cityscape at sunset. The colors should be warm and inviting, with the cool tones of the drink contrasting against the warm hues of the sunset. Use a Nikon D850 DSLR with a 85mm f/1.8 lens for a high-resolution, detailed image. The shot should be taken during the golden hour, with the setting sun providing a warm, soft light. The style should be casual and candid, as if capturing a spontaneous moment of enjoyment. Use a high-quality color film to capture the warm tones of the sunset and the cool tones of the drink. The camera settings should be set to a wide aperture to blur the background, a fast shutter speed to freeze the moment, and a moderate ISO to balance light sensitivity and noise. In post-processing, enhance the warm tones of the sunset, increase the contrast, and add a soft glow to the can to make it stand out.
