In this video from our Lightroom 4 A to Z Workshop on DVD, we will go over the Sharpening settings from the Detail Panel in Lightroom 4. The Detail Panel also includes settings for Noise Reduction, but we will go over those settings in the next video. In this article, we will be explaining the different sharpening sliders and we will also demonstrate how to correctly sharpen an image with the Detail Panel in Lightroom 4.

The Detail Panel
To expand or collapse the Detail Panel, press “Ctrl + 5.” Once you expand the Detail Panel, you will see 3 sections: the 1:1 Preview Panel, the Sharpening settings and the Noise Reduction settings. To get the best quality out of your images, it is important to understand each value in the Sharpening and the Noise Reduction settings.
1:1 Preview Panel
First, we have the 1:1 Preview Panel, which shows us a 1:1 preview of the image selected. Currently, our 1:1 Preview Panel is displaying the gray background of the image, which is not very useful. To adjust the preview in the 1:1 Preview Panel, click on the Adjust Detail Zoom Area Tool. After you have selected this tool, bring it over to an area that is useful, like the eyes of your subject, and click on that area of the image.
As you can see in our image below, we have the Adjust Detail Zoom Area Tool over our subject’s eye.
Once you click on your image, you will have a locked 1:1 preview in the Detail Panel that you can refer to when you are adjusting the Sharpening and Noise Reduction settings.
You can also zoom to 1:1 by selecting the 1:1 zoom at the top of the Navigator Panel, which can be found at the top left in Lightroom. Once you have selected the 1:1 zoom, you can simply click on your image to zoom in and out of 1:1. To adjust where you zoom into, simply click and drag your image.
A 1:1 zoom will help you see if you have correctly sharpened your image. If the Sharpening effect looks good at 1:1, then your image will most likely also look correctly sharpened when it comes out as a print.
Amount of Sharpening
The first Sharpening value in the Detail Panel is the Amount. The Amount is the overall strength of the Sharpening effect. When you drag the Amount slider to the right, it will increase the strength of the Sharpening effect and when you drag the Amount slider to the left, it will decrease the strength of the Sharpening effect.
This is what our image looks like at a 1:1 zoom with the Amount of the Sharpening effect pulled all the way down to 0.
If we drag the Amount slider all the way up to 150, we will be able to see every adjustment in complete detail because the Sharpening effect is at full effect.
This is what our image looks like at a 1:1 zoom with the Amount of the Sharpening effect pulled all the way up to 150.
Radius of Sharpening
The next Sharpening value is the Radius. The Radius adjusts the amount that the Sharpening effect extends from each line in the image. In other words, the Radius increases or decreases the thickness of the Sharpening effect. The higher the Radius, the stronger lines will appear in the image.
As you can see in our image below, the strong lines between his ears and the lines in between his cheek line and the background become stronger when we bring the Radius up.
To see the strength of any of the Sharpening values, hold down “Alt” as you move the sliders. A mask will appear over your image to show you how each Sharpening value will affect the image.
If we bring the Radius slider all the way down to 0.5 while holding down “Alt,” the edges in our image are not very strong.
When we increase the Radius, we can see that the edges in our image are much thicker.
When we let go of “Alt,” we can see that the edges in the overall image are much more prominent, especially the edges over the eyes and where the skin meets the gray background.
Detail of Sharpening
The next Sharpening value is Detail. Detail controls how much of the fine detail in the image will be sharpened. When we move the Detail slider to the right, it will increase the fine detail. When we move the Detail slider to the left, it will decrease the fine detail. When we are editing portraits, we do not want to bring the Detail up too high because we do not want to sharpen the pores and blemishes on the skin.
We can also see how Detail affects our overall image by holding down “Alt” again. When we pull the Detail up to 100, we can see that all of the pores have been sharpened.
When we decrease the Detail down, we only see the strong edge lines being sharpened.
Masking of Sharpening
The last Sharpening value is Masking, which is an overall sharpening reduction tool that allows you to mask out parts of the image so they are not affected by the sharpening. The Masking value masks more of the image as we pull the slider to the right.
When you pull the Masking slider to 100, it will only sharpen the thickest and most prominent lines in the image. To see how this effect works, hold down “Alt” while moving the Masking slider. When we move the Masking slider to the right, we will see less of the Sharpening effect. The white areas indicate where the Sharpening effects show up in the image while the black areas are where the Sharpening effects are masked out. When the Masking value is set at 0, the mask is completely white because we are revealing all of the Sharpening effects. When the Masking value is set at 100, only the strongest lines of the image will be sharpened.
In the image below, we have pulled up the Masking value all the way up to 100 while holding down “Alt.” As you can see, only the strongest lines of the image remain in this mask.
Correctly Sharpening Images
Now that we understand how each Sharpening value affects our image, we are going to dial in the correct Sharpening settings for this image. First, we are going to reset all of the settings that we previously applied. To reset settings, hold down “Alt” and click on “Reset Sharpening” in the Detail Panel.
We will raise the Amount value to 89. Next, bring the Radius up to 2.0. With Detail, we do not want to bring it up too high since this is a portrait and we do not want each pore on his face to be enhanced. We will bring the Detail up to 25 and we will leave Masking at 0.
This is what our image looks like with the correct Sharpening effects applied. Since the Sharpening effects look fine at the 1:1 zoom, the image will also come out fine as a print.
Conclusion & Learn More!
If you want to enlarge an image in Photoshop and you need to know exactly how much to sharpen the image, bring the image into Lightroom 4 first. Then, zoom in at 1:1 and if the Sharpening effects look good at 1:1 preview, then the image will print out correctly. Previewing an image at 1:1 is the easiest way to check to see if your image has been correctly sharpened.
