Visual concept

Create a high-end studio fashion portrait inspired by the uploaded blue-background reference photograph. Recreate the original composition with matching framing, focal length feel, camera position, subject scale, perspective, and overall visual balance while maintaining a realistic photographic appearance. Replace the reference model with the character from the supplied character image. Preserve the character's authentic facial identity, bone structure, skin tone, eye shape, hairstyle, proportions, and recognizable features. Avoid beautification that alters identity. The face should remain naturally expressive and true to the source character. Match the original body language closely: upper torso visible, shoulders relaxed, chin slightly elevated, eyes directed upward beyond the camera, conveying quiet confidence and contemplation. Maintain the same sense of presence and spatial positioning within the frame. Retain the rich cobalt-blue studio backdrop and the refined editorial atmosphere. Reproduce the original lighting setup with soft directional illumination, subtle facial highlights, realistic reflections on eyewear and jewelry, and smooth shadow transitions around the jawline, neck, and clothing folds. Preserve depth, dimensionality, and studio realism. Style the character in contemporary oversized street-fashion apparel. Use a premium relaxed-fit knit sweater or sweatshirt with natural fabric draping, layered with a minimalist chain necklace and lightly tinted translucent eyewear. The wardrobe may be customized to suit the character, but should maintain the same luxurious oversized silhouette and fashion-campaign aesthetic. Keep the image tightly composed with the same portrait crop and subject placement. Ensure identical camera-to-subject distance and visual weight in the frame. The final result should feel indistinguishable from a genuine professional photoshoot captured in this exact studio environment. Photorealistic editorial photography, luxury fashion campaign, cinematic studio portrait, premium streetwear styling, deep monochromatic blue backdrop, realistic skin texture, subtle film-grade contrast, detailed fabric rendering, natural lighting falloff, commercial advertising quality, shallow depth of field, magazine-cover aesthetics. Negative Prompt: Do not alter the background color or studio environment. Do not change the pose, framing, crop, perspective, subject distance, lighting direction, or gaze. Do not modify facial identity, facial proportions, skin tone, or hairstyle. Avoid excessive retouching, artificial skin smoothing, stylized illustration effects, exaggerated sharpening, extra accessories, text overlays, logos, watermarks, duplicate subjects, or unrealistic clothing physics.

Create a bold editorial campaign poster where oversized typography actively shapes the visual concept instead of simply sitting in the background. Brand: [Brand Name] Product / Campaign: [Product Or Campaign] Main Word: [Short Word] Subject / Product: [Person Or Product] Typography Function: [Shadow Or Frame Or Light Or Route] Main Color: [Color] Accent Color: [Color] Campaign Details: [Slogan Or Specs Or Date] Aspect Ratio: [9:16] Use contemporary editorial design, realistic commercial photography, bold oversized typography, and a strong high-contrast color system. Make the main word extremely large, filling roughly 50–75% of the composition. Allow letters to extend beyond the canvas, be cropped, overlap the subject, or use their negative space as part of the layout. Most importantly, give the typography a clear visual function. For example, let the letters cast shadows across the subject, frame a product, shape the lighting, create a movement path, or organize the scene in another meaningful way. The subject or product should interact naturally with this typography system so the text, photography, and graphic elements feel designed as one composition. Use one dominant color with a contrasting secondary color, black, white, and only a small amount of accent color. Add a few meaningful campaign details such as the brand name, product name, slogan, specifications, labels, route information, or small editorial text. Keep them organized and relevant to the actual concept instead of using random filler words. Keep people, products, materials, lighting, and shadows realistic and polished. The final image should feel like a finished commercial campaign key visual — bold, colorful, editorial, and visually complete.

Decision guide

Still deciding? Start with these key decision points.

1
Choose it for the controls you need

Include Nano Banana Pro in your test when you need reference-image editing, an explicit 1K/2K/4K output choice, or support for up to 8 reference images.

2
Compare alternatives by limits and price

Compare Nano Banana for a fixed 3-credit price. Compare Nano Banana 2 when Kyeo's Google Search toggle, up to 14 images, or a longer prompt is more important.

3
Use a minimal, repeatable test

Start with a few essential references and one repeatable prompt at 1K or 2K. Check the subject, text, edges, and composition, then test 4K only when you need the larger pixel dimensions.

Real-world experience

Practical guidance based on public sources, current on-site limits, and representative tasks.

The Pro name is not a substitute for testing

Kyeo can verify the available parameters, input limits, and credit prices. The Pro label does not automatically guarantee more accurate, consistent, or production-ready images; compare outputs on the same brief.

Kyeo's feature set is narrower than Google's direct API

Google documents Search grounding and Thinking for Gemini 3 Pro Image, but Kyeo's current Pro form does not expose those controls. This page covers only features available to Kyeo users.

Capabilities

Text generation and reference-image editing

Without an upload, Nano Banana Pro generates from text; after you add references, it uses those images to guide the edit.

Three resolutions and two price tiers

The `resolution` field offers 1K, 2K, and 4K. Kyeo currently charges 8 credits for 1K or 2K and 14 for 4K; a higher tier means larger output dimensions, not a quality guarantee.

Up to 8 reference images

The public source interface accepts up to 8 input images. Kyeo currently accepts JPEG, PNG, and WebP files up to 10 MB each.

Use cases

Product and scene concepts

Generate background, composition, and aspect-ratio variations from a prompt or product reference. Verify trademarks, packaging text, and product details in every result.

Posters and social graphics

Select the aspect ratio and output size for a target channel, then review spelling, anatomy, licensing, and platform requirements manually.

Multi-reference edits

Combine subject, setting, or style references in an editing test. Removing unrelated images makes each reference's effect easier to evaluate.

Prompt tips

Evaluate content and output size separately

1K and 2K currently share an 8-credit price. Keep the prompt and references fixed while comparing output, then test the 14-credit 4K tier only when its pixel dimensions are needed.

Assign a purpose to each reference

State which image defines the subject, clothing, material, or background, and begin with a small set. Adding images can create conflicts and does not automatically improve consistency.

Separate what must stay from what may change

For editing, list the subject traits to preserve, the regions that may change, and the intended aspect ratio. Manually inspect text, logos, hands, and other high-risk details.

Why choose it

One form supports text generation and reference-image editing.
It offers 1K, 2K, and 4K output-size tiers.
The current 1K and 2K price is the same, simplifying cost comparisons.
Aspect-ratio and output-format controls are explicit.

What to know first

Kyeo currently limits each upload to 10 MB, below the 30 MB limit documented by the public source interface.
4K costs 14 credits per task and is best used after composition and style are settled.
The 8-image maximum is a capacity limit; adding more images does not mean higher consistency.
Kyeo does not currently expose Search grounding or Thinking controls from Google's direct API.

Credit-saving tip

Before generating images or videos in bulk, run an A/B test with the same input on this model and similar alternatives. Confirm the result first to avoid wasting credits.
