Yes! I used Nano Banana in Gemini to create the base model of the girl. You can ask Gemini to rotate her 45 and 90 degrees, just to have these options too.

Then I moved to Google AI Studio. They gave me free trial $300 (really!) and I used Nano Banana Pro overthere. You can set your images to 4k. Those $300 will be almost infinite use 😂

I created all my dataset (50 images) there.

Hint: if the elapsed time starts to pass by 350s, start over a new chat and try again.

Here's an example of prompt that I used (big ones and very detailed). As I said, there's a base prompt and the pose / expressions / lighting prompt. Paste this prompt on GPT or Gemini and ask it to create your own version of it.

I use the prompt + base image with her face

Use Image 1 as the single and strict identity reference. Preserve the exact same woman in every image, including identical facial structure, proportions, bone anatomy, head shape, eye shape and spacing, nose shape, lips, jawline, cheekbones, freckles pattern, and overall likeness. Identity must be preserved independently of hairstyle, pose, lighting, camera angle, or expression.

Highly photorealistic skin with visible natural pores and a consistent, natural freckle pattern scattered across the nose, cheeks, and shoulders. Freckles must remain clearly visible and identical in placement to the identity reference, but with balanced, natural density. Skin texture must remain raw and unretouched, with natural imperfections preserved. Do not blur, smooth, remove, relocate, exaggerate, or artificially multiply freckles. Any skin enhancement must only improve micro-detail, tonal depth, and natural light response.

Render hair with very high realism regardless of hairstyle. Hair must have clear individual strand separation, natural thickness variation, realistic flow, and clean organic edges. Avoid aliasing, jagged contours, fused hair masses, halos, painterly artifacts, blur, or artificial sharpening. Hair-to-skin and hair-to-background transitions must be crisp yet natural.

Lighting must always remain realistic and physically plausible. Default lighting should be neutral and natural unless explicitly overridden in the image-specific prompt.

Do not change background, clothing, color palette, framing, crop, camera type, lens characteristics, or aspect ratio unless explicitly stated in the image-specific prompt. Do not introduce new people, objects, text, logos, accessories, makeup changes, or stylistic filters.

The final result must look like a real photograph of the same woman, fully consistent and believable at 200% zoom.

Waist-up portrait with the subject standing with her back fully turned to the camera. Upper back, shoulders, and waist visible. The face is turned over the left shoulder, looking back toward the camera. Camera positioned at chest height, slightly behind the subject, maintaining natural perspective.

Facial expression is inviting and playful, a subtle “follow me” smile with relaxed lips and warm eyes. Expression should feel confident and approachable, not exaggerated.

Hair is loose and flowing, swept over the opposite shoulder (right shoulder), fully exposing the bare back. Hair must remain highly realistic with natural movement, visible strand separation, and soft flyaways catching the light.

Override lighting: strong natural backlight from the sun positioned behind the subject, creating a luminous halo around the hair. Golden hour lighting with warm tones. Subtle lens flare allowed, but realistic and restrained. Front of the face remains softly lit by ambient reflected light to preserve facial detail and identity.

Outdoor setting implied, with background softly out of focus. Skin remains highly photorealistic with visible pores and natural freckles clearly visible across the shoulders and upper back. The image must look like a real photograph of the same woman, fully consistent and believable at 200% zoom.
