Multi-Region Editing Mastery

Multi-Region Editing allows you to define different areas of an image and apply different editing operations to each region, all in a single process. This creates a seamless result with perfect transitions between regions.

Key benefits of Multi-Region Editing include:

• Efficiency: Complete complex edits in a single operation instead of multiple steps
• Consistency: Automatic harmonization between regions for seamless results
• Precision: Apply exactly the right operation to each part of your image
• Intelligent Boundaries: Smart edge detection for natural transitions between regions
• Global Awareness: Each region "knows" about the others to maintain visual harmony

Let's walk through the process of setting up a multi-region edit from start to finish.

Define Your Regions

Now you'll need to define the different regions you want to edit:

1. Click "Add Region" to create your first region
   • You'll see a selection tool appear
   • Choose the appropriate selection method:
     • Rectangle: For square/rectangular areas
     • Ellipse: For circular/oval areas
     • Polygon: For custom shapes with straight lines
     • Freeform: For completely custom shapes
     • Smart Select: For automatic object selection
2. Draw your selection on the image
   • You can adjust the selection after drawing it
   • Use the handles to resize or reshape
   • Hold Shift for proportional resizing
3. Name your region (e.g., "Sky", "Foreground", "Subject")
   • Naming helps organize complex edits
   • Names are used in the prompt construction
4. Repeat the process to add more regions
   • You can create up to 5 regions in a single edit
   • Regions can overlap if needed

The key to successful multi-region editing is crafting effective prompts for each region while maintaining overall consistency.

Region "Sky": Transform to a dramatic sunset sky with purple and orange clouds.
Region "Mountains": Change to snow-covered mountains with pine trees.
Region "Lake": Convert to a clear mountain lake reflecting the sunset.
Global: Maintain consistent lighting from the sunset and a cohesive color palette.

Now that you understand the basics, let's explore some advanced techniques for multi-region editing.

Nested Regions

You can create regions within regions for more precise control:

• Parent-Child Relationships: Define a large region, then create smaller sub-regions within it
• Inheritance: Child regions inherit certain properties from parent regions
• Override Controls: Specify which properties child regions should inherit vs. override

Example of nested region prompt:

Region "Landscape": Convert to a tropical beach scene.
  Region "Palm Trees": Within the landscape, add swaying palm trees with detailed fronds.
    Region "Coconuts": On the palm trees, add coconuts with brown husks.
Region "Sky": Change to clear blue with scattered clouds.
Global: Maintain consistent tropical afternoon lighting.

Transition Regions

For complex edits, creating dedicated transition regions can improve blending:

• Create narrow regions that overlap the boundaries between main regions
• Set these regions to "Transition" mode
• The system will use these regions to create optimal blending between main regions
• Particularly useful for challenging transitions like water-to-land or sky-to-mountains

Example of transition region prompt:

Region "Sky": Transform to sunset sky.
Region "Ocean": Change to tropical ocean with waves.
Region "Sky-Ocean Transition": Create a natural horizon line with the sunset reflecting on the water surface.
Global: Maintain consistent sunset lighting throughout the image.

Masked Objects

You can use the Smart Selection tool to automatically mask complex objects:

1. Click "Smart Select" in the region tool panel
2. Click on the object you want to select (e.g., a person, car, animal)
3. The system will automatically create a precise mask around the object
4. You can refine the mask if needed using the editing tools
5. Set specific instructions for that object

This is particularly useful for:

• Changing clothing while keeping the person the same
• Modifying specific objects without affecting surroundings
• Creating "impossible" scenes with objects from different environments

Style Transfer Between Regions

You can copy the style from one region to another:

1. Define your regions as normal
2. In the region settings, click "Advanced Properties"
3. For the target region, set "Style Reference" to the source region
4. Adjust the "Style Transfer Strength" (0-100%)

Example prompt using style references:

Region "Painting": Keep this region with its impressionist painting style.
Region "Photograph": Transform this photograph to match the impressionist style of the "Painting" region while keeping the content recognizable.
Global: Create a seamless blend between the painting and the stylized photograph.

Smart object selection

Style transfer between regions

Example 1: Product in Different Environments

For this example, we'll place a product in multiple different environments within the same image:

Regions setup:

1. Region "Product": The product itself (using Smart Select)
2. Region "Scene1": Top-left quadrant of the image
3. Region "Scene2": Top-right quadrant
4. Region "Scene3": Bottom-left quadrant
5. Region "Scene4": Bottom-right quadrant

Prompt:

Region "Product": Maintain this water bottle exactly as is, with perfect preservation of the label, cap, and bottle shape.
Region "Scene1": Create a beach scene with golden sand and blue ocean waves.
Region "Scene2": Transform to a mountain hiking trail with pine trees and rocks.
Region "Scene3": Create a modern gym interior with exercise equipment.
Region "Scene4": Transform to a kitchen countertop with fresh fruits and vegetables.
Global: The water bottle should be properly integrated into each scene with consistent lighting and realistic shadows. Maintain the same size and angle of the bottle across all scenes.

Example 2: Weather Split Image

Creating an image that shows the same scene in different weather conditions:

Regions setup:

1. Region "Summer": Left half of the image
2. Region "Winter": Right half
3. Region "Transition": A vertical strip in the center (set to Transition mode)
4. Region "Buildings": The buildings that span both halves (using Smart Select)

Prompt:

Region "Summer": Create a summer scene with lush green trees, flowers, and people in summer clothing. Bright sunlight from above.
Region "Winter": Transform to a snowy winter scene with bare trees covered in snow, people in winter coats, and snow-covered ground. Soft winter light.
Region "Transition": Create a seamless transition between summer and winter, with graduated changes in foliage, ground covering, and lighting.
Region "Buildings": Keep the buildings consistent across both seasons but add appropriate seasonal decorations (summer: flower boxes, winter: holiday lights).
Global: Maintain the exact same architecture and scene composition across the entire image. The only differences should be the seasonal elements.

Example 3: Style and Medium Variations

Showing the same subject in different artistic styles:

Regions setup:

1. Region "Photo": Top-left - realistic photography
2. Region "Watercolor": Top-right - watercolor painting
3. Region "Oil": Bottom-left - oil painting
4. Region "Sketch": Bottom-right - pencil sketch
5. Region "Subject": The main subject spanning all regions (using Smart Select)

Prompt:

Region "Photo": Create a realistic photographic style with natural colors and lighting.
Region "Watercolor": Transform to watercolor painting style with visible brush strokes and color bleeding.
Region "Oil": Create an oil painting style with thick impasto texture and rich colors.
Region "Sketch": Transform to a detailed pencil sketch with hatching and shading techniques.
Region "Subject": Maintain the exact same facial features, expression, and pose across all quadrants, only adapting the medium/style.
Global: Keep the same composition and subject across all regions. Each quadrant should have a clearly different artistic style while being recognizable as the same subject.
