1. Prepare Your Image:
* Import and Select: Import your portrait into Lightroom and select it in the Library module.
* Go to Develop Module: Switch to the Develop module to begin editing.
* Basic Adjustments (Optional): Before using the Adjustment Brush, consider making some global adjustments to your image, such as exposure, white balance, contrast, and tone curves. This will establish a solid base for your retouching.
2. Select the Adjustment Brush:
* Click the Adjustment Brush icon (it looks like a paintbrush) in the tool strip beneath the Histogram panel. Or, press the shortcut key `K`.
3. Understand the Adjustment Brush Panel:
The Adjustment Brush panel will appear on the right side of your screen. Here's a breakdown of the key settings:
* Size: Adjusts the brush size. Use the slider or use the `[` and `]` keys to decrease or increase the brush size respectively. A smaller brush is better for precise work.
* Feather: Controls the softness of the brush's edge. A high feather value creates a soft, gradual transition between the adjusted area and the untouched area. A lower feather value creates a sharper transition. Use a high feather value for most portrait retouching to blend changes smoothly.
* Flow: Determines how quickly the adjustment is applied with each brush stroke. A low flow value allows for subtle, build-up effects. A higher flow value applies the adjustment more quickly. Lower flow is generally better for retouching.
* Density: Sets the maximum opacity of the adjustment. Even with multiple strokes, the adjustment will never exceed the density value. Lower density is often helpful for subtle changes.
* Auto Mask: Attempts to automatically detect edges while painting. It can be useful for painting around specific objects, but it can also be unpredictable. For skin retouching, it's usually best to leave it off.
* Show Mask Overlay: Toggles the visibility of the mask you're creating. This helps you see exactly where you're painting. You can change the mask color using the color swatch next to the checkbox. (Shortcut key: `O`)
* Erase: Switches the brush to erase mode, allowing you to remove portions of the existing mask. Hold down `Alt` (Windows) or `Option` (Mac) while using the brush to temporarily switch to Erase mode.
* New: Clears the current mask and creates a new adjustment.
4. Common Retouching Adjustments and Settings:
Here are some specific adjustments you can make with the Adjustment Brush, along with recommended starting points. Remember to experiment and adjust the values to suit your specific image:
* Skin Smoothing (Subtle Texture Reduction):
* Size: Slightly larger than the area you're retouching.
* Feather: 80-100
* Flow: 10-30
* Density: 50-70
* Sharpness: -30 to -50 (This is the key for smoothing!)
* Clarity: -5 to -15 (Optional, further reduces texture)
* Important: Paint *only* on the skin. Avoid eyebrows, eyelashes, lips, and the whites of the eyes. Apply it multiple times to build the effect.
* Blemish Removal:
* Size: Slightly larger than the blemish.
* Feather: 50-80
* Flow: 50-70
* Density: 80-100
* Clarity: -10 to -20 (This is the key for reducing the harshness of the blemish)
* Important: Paint directly over the blemish. You might need to adjust the "Heal" or "Clone" spot removal tool after using this technique. Sometimes, multiple tiny adjustments with low values are more effective than one large adjustment.
* Eye Enhancement:
* Size: Smaller, to target specific areas.
* Feather: 50-70
* Flow: 20-40
* Density: 50-70
* Iris Enhancement (Make eyes pop):
* Exposure: +0.10 to +0.30 (Subtle brightening)
* Contrast: +5 to +15 (Adds definition)
* Clarity: +10 to +20 (Adds sharpness and detail)
* Saturation: +5 to +10 (Enhances color, use sparingly)
* Whites of the Eyes (Brightening):
* Exposure: +0.10 to +0.20
* Highlights: -10 to -20 (Prevents blown-out highlights)
* Lip Enhancement:
* Size: Fit to the lips.
* Feather: 60-80
* Flow: 20-40
* Density: 50-70
* Saturation: +5 to +15 (Enhances color subtly)
* Clarity: +5 to +10 (Adds definition)
* Dodge and Burn (Contouring):
* Dodge (Brightening):
* Size: Appropriate for the area being dodged.
* Feather: 80-100
* Flow: 5-15
* Density: 50-70
* Exposure: +0.10 to +0.30 (Very subtle, build it up)
* Paint on areas where you want to increase the light (e.g., cheekbones, bridge of the nose).
* Burn (Darkening):
* Size: Appropriate for the area being burned.
* Feather: 80-100
* Flow: 5-15
* Density: 50-70
* Exposure: -0.10 to -0.30 (Very subtle, build it up)
* Paint on areas where you want to create shadows (e.g., under cheekbones, along the jawline).
5. Painting and Adjusting the Mask:
* Paint the Mask: Click and drag the brush over the areas you want to adjust. Use short, overlapping strokes for better control.
* Erase Mistakes: If you paint outside the lines, hold down `Alt` (Windows) or `Option` (Mac) while using the brush to switch to Erase mode and remove the unwanted portions of the mask. Alternatively, click the "Erase" option in the Adjustment Brush panel.
* Add to the Mask: Continue painting to add more areas to the mask.
* Adjust the Sliders: Once you've created the mask, adjust the sliders in the Adjustment Brush panel to fine-tune the effect.
6. Working with Multiple Adjustments:
* Create a New Adjustment: To apply different adjustments to different areas, click the "New" button in the Adjustment Brush panel. This will clear the current mask and allow you to create a new one with different settings.
* Edit Existing Adjustments: Click the pin on the image corresponding to the adjustment you want to modify. The sliders for that adjustment will appear in the panel.
7. General Tips for Portrait Retouching with the Adjustment Brush:
* Be Subtle: Less is often more. Over-retouching can make a portrait look unnatural and artificial.
* Zoom In: Zoom in to 100% or higher to see details and make precise adjustments.
* Use Small Increments: Make small adjustments to the sliders, rather than large ones. This allows you to fine-tune the effect and avoid overdoing it.
* Pay Attention to Skin Texture: Avoid completely removing all skin texture, as this can make the skin look like plastic. Instead, focus on reducing blemishes and imperfections while preserving some natural texture.
* Use a Graphics Tablet (Optional): A graphics tablet can provide more precise control over the brush, making it easier to create smooth and natural-looking adjustments.
* Practice: The more you practice, the better you'll become at using the Adjustment Brush to retouch portraits.
* View Before & After: Toggle the backslash key (\) to quickly view the image before and after your adjustments. This helps you to see how much you've changed the image and whether you're going overboard.
* Reset if Needed: If you make a mistake you can't undo, click "Reset" to revert all changes made with that particular adjustment brush.

2. Set the Size, Feather, Flow, and Density as described above.
3. Set Sharpness to -40 and Clarity to -10.
4. Turn off Auto Mask.
5. Zoom in to 100%.
6. Paint over the skin, avoiding eyebrows, eyelashes, lips, and eyes. Use short, overlapping strokes.
7. Zoom out and assess the results.
8. Adjust the sliders as needed to fine-tune the effect.
9. Repeat on other areas of the skin.
10. Use the spot removal tool to remove any larger blemishes not addressed by the skin smoothing brush.
By following these steps and experimenting with the Adjustment Brush settings, you can effectively retouch your portraits in Lightroom and achieve professional-looking results. Remember to always strive for a natural and balanced look.
