Core Features

1. Text to Image

This is the most fundamental and powerful feature.

How to Use:

1. Enter your description in the prompt box
   Example: "Tech product poster, metallic banana device centered, surrounded by blue light beams, 4K sharp"

2. Select aspect ratio (16:9 for posters, 1:1 for social media)

3. Add negative prompts
   Example: "watermark, blur, deformed hands, misspelled text"

4. Click "Generate"

5. Wait 10-30 seconds for the image to be created

Prompt Tips:

• Clearly define subject and action
• Specify composition and camera angle
• Indicate lighting and materials
• Note any required text content

2. Image to Image

Re-create or transform existing images with style conversion.

Use Cases:

• Change product photo backgrounds
• Convert photos to illustration style
• Adjust specific details
• Generate new images based on reference composition

How to Use:

1. Click "Image Editing" mode
2. Upload reference image (supports JPG, PNG, WebP)
3. Adjust "Reference Strength" slider (0-100%)
   • Low strength: Reference composition only, high creativity
   • High strength: Preserve original details, minor modifications
4. Enter modification description
5. Generate new image

3. Inpainting

Precisely edit specific regions of an image.

Common Uses:

• Remove unwanted elements

• Fix flaws or errors
• Add new elements

Steps:

1. Select a generated image
2. Use brush tool to mark the area to modify
3. Describe the desired new content
4. Generate partial modification result

4. Upscale

Enhance image resolution to 4K with richer details.

When to Use:

• Print output required
• Large screen displays
• High-quality poster production
• Scenarios demanding fine details

Notes:

• Upscaling consumes more credits/quota
• Better source quality yields better upscale results
• Confirm composition and content before upscaling

Advanced Techniques

Maintaining Character Consistency

When generating series images, how do you keep characters or products consistent?

Method 1: Detailed Repeated Descriptions

Same young Asian female engineer in yellow hoodie, short hair, black-frame glasses, operating equipment in lab

Use identical description statements for each generation.

Method 2: Use Image to Image

1. Generate the first satisfactory character image
2. Use this image as reference for subsequent generations
3. Set reference strength to 60-80%
4. Modify action and scene descriptions

Clear Readable Text

AI-generated text often appears blurry or misspelled. How to avoid this?

Specify in Your Prompt:

Title reads "Nano Banana Pro", subtitle reads "Professional AI Image Generation", text clear and readable, tidy typography, sharp fonts

Exclude in Negative Prompt:

blurry text, misspelled text, deformed text, unreadable text

Precise Color Control

Method 1: Specify Color Codes

Primary color #FFE629 (banana yellow), secondary #1A1A1A (dark gray), white background, high contrast

Method 2: Reference Brand Style

Apple-style minimalist design, pure white background, centered product, soft shadows

Batch Generate Variants

Need to quickly produce multiple options for client selection?

1. Enable "Batch Mode" in settings
2. Select quantity (2-4 images)
3. Each generation produces multiple different variants
4. Pick the best option for fine-tuning

Common Issues & Solutions

Generated Images Don't Meet Expectations

Cause: Prompt is too vague or ambiguous

Solution:

• Add more details (color, material, lighting)
• Clarify composition and perspective
• Add style references (e.g., "cyberpunk style," "minimalism")
• Use negative prompts to exclude unwanted elements

Deformed Hands or Faces

Cause: AI has limitations processing complex poses and details

Solution:

• Add "deformed hands, extra fingers, distorted faces" to negative prompts
• Avoid complex hand gesture descriptions
• Generate multiple times, select the most natural result
• Use inpainting to fix problem areas

Watermarks or Logos Appear

Solution:

• Add "watermark, logo, signature, text overlay" to negative prompts
• If they still appear, use inpainting to remove them
• Disable "Reference Web Images" in settings

Slow Generation Speed

Possible Causes:

• High server load (peak hours)
• Selected 4K high resolution
• Generating multiple images simultaneously

Improvements:

• Avoid peak usage times (weekday daytime)
• Preview with 2K first, then generate 4K after confirmation
• Pro users enjoy priority generation queue

Out of Credits/Quota

Free Users:

• Daily login rewards grant small credits
• Upgrade to Pro monthly/yearly for higher quota

Pro Users:

• Monthly/yearly subscribers enjoy higher generation quotas

Workflow Recommendations

Marketing Poster Production Workflow

1. Conceptualization (5 minutes)

Best Practices Summary

Prompt Writing Principles

• Structure before details: Purpose → Subject → Composition → Lighting → Style
• Specific beats abstract: "soft side lighting" is more effective than "nice lighting"
• Change one thing at a time: Makes it easier to compare and understand parameter impact

Image Management Tips

• Create project folders for organized storage
• Use descriptive filenames (e.g., "product-poster-blue-tech-v3.png")
• Save useful prompt templates for long-term reuse
• Regularly clean up unsatisfactory history
