🌟 When to Use Nano Banana: For Creativity and Consistency

Nano Banana (part of Google's Gemini 2.5 Flash Image suite) is your go-to model for creative generation and maintaining the identity of a subject across different scenes and contexts.

🎨 Nano Banana Excels At:

Character Consistency ⭐⭐⭐⭐⭐

This is its superpower. You can take a person, pet, or object from one photo and place them in entirely new environments, and they will look exactly the same every single time.

Perfect for:

  • Creating a series of images with the same character
  • Brand mascot variations across different scenes
  • Social media content with consistent personal branding
  • Storytelling through visual sequences

Creative Generation ⭐⭐⭐⭐⭐

Ideal for turning a simple concept or partial image into a fully realized creation. It excels at "imagining" details that aren't explicitly provided.

Perfect for:

  • Transforming sketches into photorealistic images
  • Creating product mockups from basic descriptions
  • Generating artistic interpretations of real photos

Style Transfers ⭐⭐⭐⭐⭐

Apply the style of one image (like a painting or artistic filter) to another while preserving the subject's core identity.

Perfect for:

  • Creating artistic versions of portraits
  • Applying vintage photo effects while maintaining detail
  • Brand imagery with consistent visual themes

Multi-Image Blending ⭐⭐⭐⭐⭐

Seamlessly merge subjects from different photos into a single, coherent scene that looks naturally composed.

Perfect for:

  • Family portraits combining separate photos
  • Product placement in realistic environments
  • Creative composite imagery

🎯 Nano Banana Use Case Example:

"I have a photo of my dog, and I want to create a series showing him as a superhero, a medieval knight, a space explorer, and a detective – all while keeping him looking exactly the same."

Result: Nano Banana will maintain your dog's exact appearance, fur patterns, and facial features across all four completely different scenarios.

⚑ When to Use Flux Kontext: For Precision and Realism

Flux Kontext is a surgical tool designed to understand an existing image and modify it based on precise, literal instructions while preserving the original image's integrity.

πŸ”§ Flux Kontext Excels At:

Precise Local Edits ⭐⭐⭐⭐⭐

Its core strength is changing one specific element while leaving everything else completely untouched.

Perfect for:

  • "Change the red car to blue"
  • "Remove the logo from this shirt"
  • "Replace the cloudy sky with a sunset"
  • "Turn the wooden table into marble"

Advanced Relighting ⭐⭐⭐⭐⭐

Flux Kontext is exceptional at realistically changing the lighting of an environment while maintaining natural shadows, reflections, and atmospheric consistency.

Perfect for:

  • Converting daytime photos to golden hour
  • Adding dramatic studio lighting to portraits
  • Fixing poorly lit product photos
  • Creating mood lighting for interior shots

Typography and Text Handling ⭐⭐⭐⭐⭐

It can add, modify, or remove text on signs, posters, or objects within images with remarkable accuracy and realistic integration.

Perfect for:

  • Customizing signage in photos
  • Adding text to product mockups
  • Editing existing text in screenshots
  • Creating localized versions of marketing materials

Atmosphere Preservation ⭐⭐⭐⭐⭐

When you need to make changes without altering the mood, shadows, reflections, and overall feeling of the original photo.

Perfect for:

  • Professional photo retouching
  • E-commerce product adjustments
  • Real estate photo enhancement
  • Social media content refinement

🎯 Flux Kontext Use Case Example:

"I have a perfect product photo, but the background wall is white and I need it to be navy blue. Also, the lighting is too harsh – I want softer, warmer lighting."

Result: Flux Kontext will change the wall color and adjust the lighting while perfectly maintaining all the product details, shadows, and reflections to look completely natural.
