Unsharp Mask
Use Unsharp mask to fine-tune a sharpening filter effect on the final downsampled image. You can control the intensity of the effect, radius of the effect (measured in pixels), and a threshold of contrast that is ignored. This effect uses the same options as Adobe Photoshop’s Unsharp Mask filter.
In Unsharp Mask, you have the following filtering options:
Option | Description |
---|---|
Amount | Controls the amount of contrast applied to edge pixels. The default is 1.75. For high-resolution images, you can increase it to as high as 5. Think of Amount as a measure of filter intensity. The range is 0-5. |
Radius | Determines the number of pixels surrounding the edge pixels that affect the sharpening. For high-resolution images, enter from 1 through 2. A low value sharpens only the edge pixels; a high value sharpens a wider band of pixels. The correct value depends on the size of the image. The default value is 0.2. The range is 0-250. |
Threshold | Determines the range of contrast to ignore when the unsharp mask filter is applied. In other words, this option determines how different the sharpened pixels must be from the surrounding area before they are considered edge pixels and are sharpened. To avoid introducing noise, experiment with values between 0–255. |
Sharpening is described in Sharpening Images.
Create Dynamic Media Image Profiles
To define advanced processing parameters for other asset types, see Configuring Asset Processing.
See Profiles for Processing Metadata, Images, and Videos.
See also Best Practices for Organizing your Digital Assets for using Processing Profiles.
To create Dynamic Media Image Profiles:
-
Select the Adobe Experience Manager logo and navigate to Tools > Assets > Image Profiles.
-
Select Create so you can add an Image Profile.
-
Enter a profile name, and values for unsharp mask, crop, or swatch, or both.
Use a profile name that is specific to its intended purpose. For example, if you want to create a profile that generates swatches only – that is, Smart Crop is disabled (turned off) and Color and Image Swatch is enabled (turned on) – use the profile name “Smart Swatches”.
See also Smart Crop and Smart Swatch Options and Unsharp Mask.
-
Select Save. The newly created profile appears in the list of available profiles.
Edit or delete Dynamic Media Image Profiles
-
Select the Experience Manager logo and navigate to Tools > Assets > Image Profiles.
-
Select the Image Profile that you want to edit or remove. To edit it, select Edit Image Profile. To remove it, select Delete Image Profile.
-
If editing, save the changes. If deleting, confirm that you want to remove the profile.
Apply a Dynamic Media Image Profile to folders
When you assign an Image Profile to a folder, any subfolders automatically inherit the profile from its parent folder. This workflow means that you can assign only one Image Profile to a folder. As such, consider carefully the folder structure of where you upload, store, use, and archive assets.
If you assigned a different Image Profile to a folder, the new profile overrides the previous profile. The previously existing folder assets remain unchanged. The new profile is applied on the assets that are added to the folder later.
Folders that have a profile assigned to it are indicated in the user interface using the profile name that appears in the card.
You can apply Image Profiles to specific folders or globally to all assets.
You can reprocess assets in a folder that already has an existing Image Profile that you later changed. See Reprocess assets in a folder after you have edited its processing profile.
Apply Dynamic Media Image Profiles to specific folders
You can apply an Image Profile to a folder from within the Tools menu or if you are in the folder, from Properties. This section describes how to apply Image Profiles to folders both ways.
Folders that have a profile already assigned to it are indicated by the display of the profile’s name directly below the folder name.
You can reprocess assets in a folder that already has an existing video profile that you later changed. See Reprocess assets in a folder after you have edited its processing profile.
Apply Dynamic Media Image Profiles to folders from Profiles user interface
-
Select the Experience Manager logo and navigate to Tools > Assets > Image Profiles.
-
Select the Image Profile that you want to apply to a folder or multiple folders.
-
Select Apply Processing Profile to Folders and select the folder or multiple folders you want to use to receive the newly uploaded assets and select Apply. Folders that have a profile already assigned to it are indicated by the display of the profile’s name directly below the folder name.
Apply Dynamic Media Image Profiles to folders from Properties
-
Select the Experience League logo and navigate to Assets. Then navigate to the parent folder of the folder to which you want to apply an Image Profile.
-
On the folder, select the check mark to select it and then select Properties.
-
Select the Image Profiles tab. From the Profile Name drop-down list, select the profile, then select Save & Close. Folders that have a profile already assigned to it are indicated by the display of the profile’s name directly below the folder name.
