How to Lighten or Darken Specific Areas in Adobe Lightroom: Master Local Adjustments with Precision


Local adjustments in Adobe Lightroom transform ordinary photos into compelling visual stories by allowing you to selectively brighten or darken specific areas of your images. Whether you’re enhancing portrait lighting, balancing landscape exposures, or creating dramatic effects, mastering these targeted editing techniques will revolutionize your post-processing workflow.

Understanding Local Adjustments vs Global Edits

While global adjustments affect your entire photograph uniformly, local adjustments provide surgical precision in your editing process. Think of it as the difference between painting an entire wall versus carefully highlighting architectural details—both have their place, but local adjustments give you creative control exactly where you need it.

Why Local Adjustments Matter for Professional Results

Professional photographers rely on selective exposure adjustments to:

  • Draw viewer attention to key subjects
  • Balance challenging lighting conditions
  • Create depth and dimension in flat images
  • Enhance mood and atmosphere
  • Correct exposure problems in specific areas without affecting the entire photo

Essential Tools for Selective Brightening and Darkening

Adobe Lightroom offers multiple approaches to lighten or darken specific areas, each with unique strengths for different editing scenarios.

The Masking Panel: Your Central Command

Since Lightroom Classic 11.0 and Lightroom 5.0, all local adjustment tools live within the unified Masking panel. Access it through:

  • Desktop: Click the Masking icon below the histogram (Shift+W)
  • Mobile: Tap the Selective tool in the editing menu
  • Lightroom Classic: Find it in the Develop module’s tool strip

AI-Powered Selection Tools for Instant Precision

Modern Lightroom leverages artificial intelligence to automatically detect and select complex areas, making targeted adjustments faster than ever.

Select Subject: One-Click Intelligence

The Select Subject tool uses machine learning to instantly identify and mask your main subject:

  1. Open your photo in the Develop module
  2. Click Masking > Select Subject
  3. Lightroom analyzes and creates an automatic selection
  4. Fine-tune using the Exposure slider to brighten or darken
  5. Adjust Shadows and Highlights for nuanced control

Pro Tip: After selecting your subject, use the Invert option to quickly adjust the background instead—perfect for creating separation or mood.

Select Sky: Transform Landscape Exposures

Landscape photographers frequently need to balance bright skies with darker foregrounds. The Select Sky tool automates this previously tedious process:

  1. Navigate to Masking > Select Sky
  2. Watch as Lightroom intelligently identifies sky regions
  3. Reduce Exposure to recover blown highlights
  4. Increase Vibrance for dramatic sunset colors
  5. Add graduated filter effects with the Dehaze slider

Select People: Portrait Perfection

For portrait retouching, the Select People tool offers unprecedented control:

  1. Choose Masking > Select People
  2. Lightroom detects all people in your frame
  3. Select specific individuals or body parts:
    • Face and skin for exposure adjustments
    • Eyes for brightening and clarity
    • Hair for texture enhancement
    • Clothing for color grading

Manual Selection Tools for Custom Control

When AI selections need refinement or you’re working with abstract compositions, manual tools provide complete creative freedom.

Brush Tool: Paint Your Adjustments

The Adjustment Brush remains the most versatile tool for irregular selections:

Essential Brush Settings:

  • Size: Use brackets [ ] to quickly adjust
  • Feather: Shift + brackets for edge softness
  • Flow: Controls application speed (10-25% for subtle building)
  • Density: Maximum effect strength (start at 50-70%)
  • Auto Mask: Enables edge detection for precise boundaries

Technique for Natural Results:

  1. Start with low Flow settings (15-20%)
  2. Build up effects gradually with multiple strokes
  3. Use the Erase mode (hold Alt/Option) to refine edges
  4. Toggle overlay visibility (O key) to check your selection

Linear Gradient: Smooth Transitions

Perfect for horizons, architectural elements, or creating depth:

  1. Click and drag from the starting point to end point
  2. Adjust the gradient angle by rotating the center pin
  3. Modify transition smoothness with the feather handles
  4. Combine multiple gradients for complex effects

Creative Applications:

  • Darken sky gradually toward the horizon
  • Create light falloff in architectural interiors
  • Simulate graduated neutral density filters
  • Add atmospheric perspective to landscapes

Radial Filter: Spotlight Effects

The Radial Filter excels at creating vignettes, spotlights, and focus areas:

  1. Click and drag to create an elliptical selection
  2. Adjust size and shape using corner handles
  3. Control feather amount for natural blending
  4. Use Invert to affect inside or outside areas

Advanced Radial Techniques:

  • Stack multiple radials for complex lighting
  • Create off-center vignettes for rule-of-thirds compositions
  • Simulate lens flares or light sources
  • Isolate subjects with subtle darkening around them

Advanced Masking Techniques

Range Masking: Precision Through Parameters

Refine any mask using specific image characteristics:

Luminance Range Masking:

  • Target specific brightness levels
  • Perfect for separating highlights from shadows
  • Adjust range and smoothness for natural transitions

Color Range Masking:

  • Select based on specific color values
  • Ideal for sky replacements or color-specific adjustments
  • Use the eyedropper to sample target colors

Depth Range Masking (for compatible files):

  • Utilize depth map information from portrait mode photos
  • Separate foreground from background effortlessly
  • Available for HEIC files with embedded depth data

Combining and Refining Masks

Modern Lightroom allows sophisticated mask combinations:

  1. Add: Expand your selection with additional tools
  2. Subtract: Remove areas from existing masks
  3. Intersect: Create selections where masks overlap
  4. Duplicate: Copy masks for similar adjustments

Professional Workflow for Selective Adjustments

Step 1: Global Corrections First

Always establish your baseline exposure before local adjustments:

  • Set proper white balance
  • Adjust overall exposure
  • Correct lens distortions
  • Apply profile corrections

Step 2: Plan Your Local Adjustments

Before creating masks, identify:

  • Which areas need brightening or darkening
  • The emotional impact you want to achieve
  • Natural light direction in the scene
  • Viewer’s visual journey through the image

Step 3: Build Adjustments Gradually

Start conservative and build intensity:

  1. Create initial mask with subtle adjustments
  2. Fine-tune selection boundaries
  3. Layer multiple masks for complex effects
  4. Use brush tool for final refinements

Step 4: Maintain Natural Appearance

Avoid these common pitfalls:

  • Over-brightening eyes (uncanny valley effect)
  • Creating obvious mask edges
  • Ignoring natural light direction
  • Excessive local contrast (HDR-like appearance)
