He is wearing a charcoal gray sweater with a subtle ribbed texture and dark aviator sunglasses. In his right hand, he casually holds a black leather bag, while his left hand rests in his pocket.

Prompt 2: Urban Motorcycle Portrait with Cool Cinematic Grading

Use This:

"Ultra-realistic cinematic photo, vertical. A young, stylish man with the exact same face and facial features as the reference image – matching beard/stubble style, density, and placement, along with identical nose, eyes, cheeks, and eyebrows. The only variation is his facial expression and hair positioning beneath the hoodie. He is sitting casually on a parked motorcycle on a city street, one hand resting on the bike handle, the other adjusting his jacket near the zipper. He faces slightly sideways, looking off into the distance with a calm, confident, and serious expression. Wearing a dark gray hoodie with the hood up, his hair neatly styled underneath. The camera angle is slightly low and side-facing, with chest-level framing for a cinematic, confident feel. The background is softly blurred, showing an urban street with a few cars and trees, adding realistic depth of field. Lighting is soft natural daylight with balanced contrast and smooth tones, free from harsh shadows. The color grading is cool and cinematic, ultra-sharp, and photorealistic, with full-body proportions. Negative prompt: cartoon, CGI, illustration, altered facial hair, distorted face, extra limbs, blur, noise, oversharpening, unrealistic lighting."

The background features large, soft, out-of-focus bokeh lights in warm hues of red and orange, reminiscent of a busy city street or carnival atmosphere. The image should emulate a vintage 35mm film photography style, with visible fine film grain, slightly dark shadows, and a warm red/orange color tone. The shot should feel soft and dreamy, as if capturing a moment from a nostalgic memory. The overall mood should evoke warmth and quiet intimacy."

1. Launch Gemini Nano Banana Pro

• Open the Gemini app or website and switch to the image generation section, then select the Nano Banana Pro model.

2. Choose Your Creation Method

• Decide whether you want to upload a real boy's photo ("Edit image") or generate a fully AI portrait from text only ("Create image").
• If editing, upload a clear, well-lit portrait with the full face visible and good lighting.
• If generating from scratch, skip the upload step.

3. Paste Your DSLR-Style Prompt

• Copy one of the 15 prompts above and paste it into the prompt field.
• Include essential details like age range, specific outfit descriptions, background setting, lens simulation (e.g., "50mm f/1.8"), lighting style, and "DSLR-level, ultra-realistic portrait."

4. Add Negative Prompts (Optional)

• For cleaner results, add a brief negative line such as: "no distortion, no plastic skin, no AI artifacts, no blur, no unrealistic lighting."
• This helps the AI avoid common generation issues.

5. Set Quality Preferences

• Choose vertical portrait orientation for social media and profile pictures.
• Select the highest quality/resolution option available for maximum detail.
• Ensure "ultra-realistic" or "photorealistic" mode is enabled if available.

6. Generate Your Portrait

• Click Generate and wait a few seconds for Nano Banana Pro to render the DSLR-quality portrait.
• The processing typically takes 10-30 seconds depending on complexity.

7. Refine and Regenerate

• If the output isn't perfect, make small adjustments with follow-up prompts like "softer background bokeh," "make lighting warmer," "sharper focus on eyes," or "reduce shadows on face."
• Regenerate until you achieve the desired professional result.

8. Download and Share

• Once satisfied, download the final image in the highest resolution available.
• Use for social media posts, Instagram profiles, modeling portfolios, thumbnails, or professional display pictures.
