深红色调极简主义红宝石摄影

Place the ruby on a minimalist surface. The entire scene should be covered in deep red tones, with natural light and shadows interwoven, a simple background, creative composition, and an overall clean and concise look. This is perfect for jewelry photography, commercial photography, and product photography, with close-up shots of the ruby, 8K resolution, Unreal Engine, realistic rendering, fashion, depth of field, and ultra-high definition. --ar 3:2 --q 2 --v 5.1 --s 750 --style raw
