Master the three key tips for Grok Imagine: 1. Be extremely specific and detailed (describe the subject, pose, lighting, style, atmosphere, and camera, e.g., "85mm lens, shallow depth of field"). 2. Explicitly mention the artist/style (e.g., "photorealistic, cinematic style" or "Ultra-HD 8K"). 3. Maintain a clear structure: start with the subject → add environment/details → finally add technical/quality enhancement elements.
