This tutorial uses the three chimneys photo from the Develop folder. Make sure you have completed the import process from Exercise 2E or follow the import steps provided.
Workflow Overview
Import and Select
Import images from the Develop folder and select the three chimneys photo for sharpening practice
Global Sharpening
Use the Detail panel to apply overall sharpening with optimal Amount settings

Sharpening Within the Detail Panel
- If you have not imported the photos that were imported in Exercise 2E:
- Navigate to the Library module.
- Click Import at the bottom left of the interface.
- In the import dialog, locate your source files under Source: navigate to Desktop > Class Files > Lightroom Class and select the Develop folder.
- Ensure Add is selected at the top above the photo thumbnails.
- Click Import in the bottom right to complete the process.
Press G to enter the Library module's Grid View (if not already active).
Select the three chimneys photograph (_CAS4871) from your image grid.
Press D to switch to the Develop module, where all sharpening adjustments take place.
In the Navigator panel (top left), click 1:1 to view the image at 100% magnification. This zoom level is crucial for accurate sharpening assessment—anything less can be misleading.
Within the Navigator panel, position the bounding box over the top middle section of the leftmost chimney. This area contains the detail structures that will best demonstrate sharpening effects:
Expand the Detail panel on the right side of the interface if it isn't already visible.
Under the Sharpening section, drag the Amount slider to its maximum value of 150 to observe the extreme effect.
Notice how the excessive sharpening creates harsh artifacts and an unnatural appearance—a common mistake that degrades image quality.
Click directly on the 150 value to make it editable.
Enter 65 and press Return (Mac) or Enter (Windows) to apply a more conservative, professional-grade sharpening amount.
Toggle the Switch
at the top-left corner of the Detail panel to compare the before and after states.The refined approach enhances detail without introducing unwanted artifacts—the hallmark of professional sharpening technique.
Sharpening Amount Values
| Feature | Setting | Result |
|---|---|---|
| 150 (Maximum) | Way too sharp | Oversharpened |
| 65 (Recommended) | Much better | Balanced |
| 0 (Default) | No sharpening | Soft |
Always view your image at 1:1 (100%) zoom when applying sharpening. This ensures you see the actual effect without scaling artifacts that can mislead your adjustments.

Sharpening Part of the Photo Using a Mask
Global sharpening affects the entire image uniformly, but sophisticated editing often requires selective enhancement. Professional photographers frequently need to sharpen specific areas—such as a subject's eyes while preserving smooth skin, or architectural details while maintaining clean skies. Lightroom's masking feature provides this precision control.
In the Detail panel, locate the Masking slider and click to activate this powerful selective tool.
Hold Option (Mac) or Alt (Windows) while slowly dragging the slider to the right. This reveals the masking overlay, showing exactly where sharpening will be applied.
Toggle the Option (Mac) or Alt (Windows) key while maintaining your position on the slider. Pressing the modifier key displays the black-and-white mask; releasing it shows the color image. In the mask visualization, black areas receive no sharpening, while white areas receive full sharpening intensity.
Professional Tip: Masking is invaluable for portrait work, allowing you to sharpen facial features like eyes and eyebrows while protecting skin texture. In landscape photography, it helps enhance foreground details while preserving smooth sky gradations.
Set the Masking value to 75 for optimal selective sharpening in this architectural image.
Use the Switch
in the top-left corner of the Detail panel to toggle between the original and sharpened versions multiple times.The result demonstrates sophisticated selective enhancement—detail areas are crisper while smooth surfaces remain natural and artifact-free.
In sharpening masks, black areas receive NO sharpening while white areas receive full sharpening. This selective approach prevents over-sharpening of smooth areas like skin or sky.
Mask Visualization
| Feature | Mask Color | Sharpening Applied |
|---|---|---|
| Black areas | No sharpening | Smooth surfaces protected |
| White areas | Full sharpening | Details enhanced |
| Gray areas | Partial sharpening | Graduated effect |
