You’ve mastered the basic sliders in Lightroom’s Develop module – exposure, contrast, highlights, and shadows. Those global adjustments are essential for setting the overall look of your image. But what happens when only a part of your photo needs attention? Perhaps a sky that’s too bright, a face that needs a subtle lift, or a foreground element that could use more punch?

This is where Lightroom’s Local Adjustment Tools come into play. These powerful brushes and filters allow you to selectively apply edits to specific areas of your image, giving you unparalleled control and helping you achieve truly professional results. Think of it as painting light and color onto your photograph.

In this detailed guide, we’ll dive deep into the three primary local adjustment tools: the Adjustment Brush, the Radial Filter, and the Graduated Filter.

The Philosophy of Local Adjustments

Global adjustments affect every pixel in your image. Local adjustments, on the other hand, are like surgical strikes. They allow you to:

  • Balance Exposure: Brighten specific shadows or darken blown-out highlights without affecting the rest of the image.
  • Enhance Detail: Sharpen eyes, add clarity to textures, or soften distracting elements.
  • Refine Color: Desaturate distracting colors, warm up skin tones, or cool down an overly warm sky.
  • Create Focus: Draw the viewer’s eye to your subject by subtly enhancing or diminishing surrounding areas.

These tools are non-destructive, just like global adjustments. You can always refine, remove, or reset your local edits without affecting the original image.

Understanding the Local Adjustment Panel

Before we dive into each tool, let’s locate their common home in the Develop Module:

  • Locate the Tools: In the Develop Module (D key), look just below the Histogram panel, above the Basic panel, on the right side. You’ll see three icons:
    • Graduated Filter (Rectangle fading to transparent) (Image 4)
    • Radial Filter (Circle/Ellipse) (Image 5)
    • Adjustment Brush (Brush)(Image 6)
Caption: Find the Graduated Filter, Radial Filter, and Adjustment Brush icons just below the histogram in the Develop module
  • The Adjustment Sliders: When you select any of these tools, a new panel appears directly below them, containing the same familiar sliders you see in the Basic panel (Exposure, Contrast, Highlights, Shadows, etc.), plus a few unique ones. These sliders only affect the area where you apply the local adjustment.
  • Resetting Local Adjustments: Each local adjustment you make is a separate “pin.” You can select a pin and click the “Reset” button at the bottom of the adjustment panel, or right-click the pin and choose “Delete.”

1. The Graduated Filter: Perfecting Horizons and Skies

The Graduated Filter is ideal for making gradual adjustments across a straight line, mimicking the effect of a real-world graduated neutral density (ND) filter. It’s most commonly used for balancing exposure between the sky and foreground in landscapes.

When to Use It:

  • Darkening an overly bright sky.
  • Brightening a dark foreground.
  • Adding contrast or clarity to specific horizontal sections.
  • Creating a subtle vignette from the top or bottom.

How to Use It:

  1. Select the Tool: Click the Graduated Filter icon (or press M).
  2. Reset Settings: Before you start, it’s a good habit to click “Reset” at the bottom of the adjustment panel to ensure all sliders are at zero.
  3. Draw the Filter: Click and drag from one side of your image to the other.
    • Drag from Top Down: Applies the effect strongest at the top, gradually fading towards the bottom line.
    • Drag from Bottom Up: Applies the effect strongest at the bottom, gradually fading towards the top line.
    • Hold Shift: Constrains the filter to a perfectly horizontal or vertical line.
  4. Understand the Lines: You’ll see three lines:
    • Solid Line: Where the adjustment is at full strength.
    • Dashed Line (Middle): The transition point.
    • Solid Line (Bottom): Where the adjustment fades to zero.
    • The wider the gap between the solid lines, the softer the transition.

  1. Adjust the Sliders: With the filter active (the pin will be selected), use the sliders in the adjustment panel to apply your desired changes (e.g., reduce Exposure, increase Clarity, slightly decrease Saturation to a bright sky).
  2. Refine the Filter:
    • Move: Click and drag the central pin to reposition the entire filter.
    • Rotate: Hover over the center line until a curved arrow appears, then click and drag to rotate the filter.
    • Adjust Feathering: Drag the top or bottom solid lines to change the softness of the transition.
  3. Visualize the Mask: Check “Show Selected Mask Overlay” (bottom of the image preview or press O key) to see the red overlay indicating where the adjustment is being applied. This is incredibly helpful!

Pro Tip: You can apply multiple Graduated Filters to different areas of your image.

2. The Radial Filter: Emphasizing Your Subject

The Radial Filter allows you to create elliptical or circular adjustments. It’s fantastic for creating subtle vignettes that draw attention to a subject, or for selectively brightening/darkening a particular area.

When to Use It:

  • Creating a subtle spotlight effect on a subject.
  • Darkening or brightening the edges of a portrait.
  • Adding focus to a specific element in your photo.
  • Applying a soft glow to a light source.

How to Use It:

  1. Select the Tool: Click the Radial Filter icon (or press Shift+M).
  2. Reset Settings: Click “Reset” in the adjustment panel.
  3. Draw the Filter: Click and drag to draw an ellipse or circle.
    • Hold Shift: Creates a perfect circle.
    • Hold Alt/Option: Draws the filter from the center outwards.
  4. Adjust the Sliders: Use the sliders to make your adjustments.
  5. Inner vs. Outer Adjustment:
    • By default, the adjustment is applied to the area outside the ellipse. This is perfect for vignetting (darkening edges).
    • To apply the adjustment to the area inside the ellipse, check the “Invert” box at the bottom of the Radial Filter panel. This creates a spotlight effect.
  6. Refine the Filter:
    • Move: Drag the central pin.
    • Resize: Drag the handles on the edge of the ellipse.
    • Rotate: Hover outside the ellipse until a curved arrow appears, then drag.
    • Feathering: Adjust the “Feather” slider in the adjustment panel. A higher feather value creates a softer transition.

3. The Adjustment Brush: Precision Painting

The Adjustment Brush offers the most granular control, allowing you to “paint” adjustments onto specific areas of your image with a brush. This is your go-to for localized dodging and burning, eye enhancements, skin smoothing, and more.

When to Use It:

  • Brightening or darkening specific objects (dodging and burning).
  • Enhancing eyes (sharpening, brightening irises).
  • Smoothing skin imperfections.
  • Adding texture or clarity to specific elements.
  • Saturating or desaturating small areas.

How to Use It:

  1. Select the Tool: Click the Adjustment Brush icon (or press K).
  2. Reset Settings: Click “Reset” at the bottom of the adjustment panel.
  3. Brush Settings (at the bottom of the adjustment panel):
    • Size: Adjusts the brush diameter. Use the [ and ] keys for quick changes.
    • Feather: Controls the softness of the brush edge. A higher feather creates a softer edge.
    • Flow: How quickly the adjustment is applied with each stroke. Lower flow allows for more gradual build-up.
    • Density: The maximum strength of the brush stroke.
    • Auto Mask: Crucial for precision! When checked, Lightroom tries to detect edges and prevent your brush strokes from spilling over.
  4. Paint Your Adjustments:
    • Set your desired adjustments using the sliders (e.g., increase Exposure, increase Clarity).
    • Paint over the area you want to affect. A small pin will appear where you start painting.
    • Show Selected Mask Overlay (O key): Again, use this to see exactly where your brush strokes are going (the red overlay).
  5. Erase (Hold Alt/Option): While holding Alt/Option, the brush turns into an eraser, allowing you to remove parts of your adjustment.
  6. Multiple Brush Strokes: You can create multiple brush strokes (and pins) for different areas or for different adjustments. Each pin represents a separate set of adjustments.
  7. Refine Your Brush Work:
    • Select a Pin: Click on an existing pin to reactivate its brush strokes and modify its sliders.Show Original and New Pins: You can click the “New” button in the adjustment panel to start a fresh adjustment with a new brush, or “Edit” to modify an existing one.

Practical Applications and Workflow Tips

  • Dodging and Burning: Use the Adjustment Brush with increased Exposure (dodging) or decreased Exposure (burning) to sculpt light and shadow.
  • Eye Enhancement: Create a new Adjustment Brush preset with increased Exposure, Clarity, and Sharpening. Paint over the irises.
  • Skin Smoothing: Use an Adjustment Brush with slightly negative Clarity and Sharpening. Paint over areas of skin that need softening.
  • Landscape Pop: Use a Graduated Filter for the sky, and then an Adjustment Brush to add clarity and vibrance to foreground elements.
  • Less is More: Start with subtle adjustments. Overdoing local edits can make your image look artificial. Build up the effect slowly.
  • Zoom In: For precise brushwork, zoom in to 1:1 (100%) or even 2:1.
  • Toggle Before/After: Press the \ (backslash) key to quickly see the global before/after. For local adjustments, use the individual tool’s on/off switch (the eye icon next to the tool name).
  • Practice! The best way to master these tools is to experiment with them on a variety of your own images.

Lightroom’s local adjustment tools are what truly elevate your editing from good to great. They provide the precision and control needed to make your subjects pop, balance challenging exposures, and refine every detail. Spend time with each tool, understand its nuances, and watch your images transform. Happy editing!
