On June 19, Picts by AI (@pictsbyai) shared on X an extensive prompt for Gemini Nano Banana 2 in the Google app. It is not a generic "black and white portrait": it describes pose (45°), swept-back hairstyle with flyaways, hand gesture with clock, side lighting at 45°, overexposed white gradient background, B/W conversion with raised blacks, film grain and EXIF ​​parameters (85mm, f/2.8, 1/500s, ISO 100).

Example posted in the thread (an image in the original post). @pictsbyai

Steps

  1. Open Gemini App and select image generation with Nano Banana 2.
  2. Paste the complete prompt below.
  3. Ask for a vertical 3:4 ratio if it is not respected.
  4. Change “male model” for “female model” or upload a reference photo if the app allows it.

Prompt to copy

A young adult male model stands in a medium shot with his body turned at a relaxed 45-degree angle, wearing a crisp white button-down shirt with an unbuttoned collar. His dark gray hair is cut in a three to four inch swept-back wavy taper grazing his nape, styled straight back with natural root lift, medium-hold product, and a slight glossy sheen, featuring coarse natural waves and visible flyaways that organically break the silhouette. His facial expression is serious and posed, with slightly furrowed eyebrows, slightly squinting eyes looking away from the camera, and a closed neutral mouth. His right hand is raised near his waist in an organic, mid-air casual gesture with loosely curved fingers, adorned with a ring and a rectangular tank watch, establishing a natural visual hierarchy from his face down to the collar and relaxed hand. He is isolated outdoors against a pristine, shallow depth-of-field background consisting of a blurred, hazy horizon of water that transitions into an open atmospheric space. This environment forms a perfectly smooth, matte pure white to light gray gradient with no distinct edges. Bathed in moderately directional, single-source natural daylight from a 45-degree side angle, the scene embraces a monochromatic black and white color profile with medium contrast and neutral temperature. The high-key soft light with ambient fill casts short, soft-edged gray shadows under his jaw, along the right side of his face, and deep within the folds of his shirt, while bright, blown-out highlights illuminate his nose bridge, his relaxed shoulders, and the entirely overexposed background. The mood is sophisticated, calm, and dramatically timeless, evoking a classic cinematic feel. Captured as a realistic digital photograph echoing 90s minimalist editorial fashion photography, the image is rendered tack sharp on the subject's face and watch using an 85mm lens at f/2.8, 1/500s, and ISO 100, finalized with a strict black and white conversion, lifted blacks, and subtle film grain, framed in a 3:4 aspect ratio utilizing an asymmetric rule of thirds composition.

Text in English according to the original publication. Single long sentence prompt: works well in Gemini because of its level of photographic detail.

What makes this prompt special

It is an example of cinematic prompt in continuous prose: it does not use lists or sections, but covers pose, hair, expression, hand, background, color temperature, shadows, highlights, mood, era (90s editorial), lens and post-processing (lifted blacks, film grain). That level of specification reduces the “generic AI look.”

The post exceeded 2,600 views and accumulated 124 likes and 57 saves, with the “Made with AI” tag. The use of Nano Banana 2 in Gemini stands out compared to the usual ChatGPT prompts in the same editorial niche.

Adaptations

Replace "white button-down shirt" with a black suit or knit sweater for another mood. Remove “black and white conversion” for natural color. Add “use uploaded reference photo for facial identity” if you generate with your own portrait.

Before publishing

Review the Google Gemini terms for generating images and using portraits. Do not use results as commercial fashion photography without checking image rights.
