Prompt Engineering techniques.
This is how I learned to tweak any prompt, or image. It’s a lot of info so take it in sections. Here’s a clean, practical Gemini Image Command Prompt List you can copy-paste from when building image prompts. I’ve grouped them by function and tuned them for Gemini’s image generation + identity lock-in workflows 🔒 Identity Lock-In Commands ✨Use these when attaching a reference photo. Identity lock-in: Preserve facial structure, proportions, and likeness from the uploaded reference image Facial fidelity: Do not alter bone structure, eye shape, nose, lips, or jawline Exact likeness: Match the reference subject’s facial identity with high accuracy Consistent subject: The generated image must depict the same individual as the uploaded photo Age preservation: Maintain the subject’s apparent age Ethnicity preservation: Do not change skin tone or ethnic features No face swapping: Do not merge or blend with other faces 🎨 Style & Artistic Direction Hyper-realistic Ultra-realistic Cinematic Photorealism Painterly Fantasy realism Ethereal Angelic Goddess aesthetic Dark fantasy Soft fantasy glow Editorial fashion style Fine art portrait 📸 Camera & Photography Commands DSLR quality Studio lighting Natural light Soft diffused lighting Rim lighting Golden hour lighting Low-key lighting High-key lighting Shallow depth of field Bokeh background 85mm portrait lens 50mm lens Macro detail 🌈 Lighting & Mood Modifiers Soft ambient glow Volumetric lighting Light rays Halo lighting Moonlit Candlelit Dramatic shadows Moody atmosphere Dreamlike lighting Warm color grading Cool color grading 🧬 Detail & Quality Enhancers Extreme detail High texture fidelity Skin texture visible Natural pores Sharp focus Crisp edges Balanced contrast Noise-free No blur Professional retouching 🖼️ Composition Commands Centered portrait Rule of thirds Symmetrical composition Head-and-shoulders portrait Full-body portrait Dynamic pose Elegant posture
