Understanding Color Management with AEM Dynamic Media understanding-color-management-with-aem-dynamic-media
In this video we explore Dynamic Media Color Management, and how it can be used to provide color correction preview capabilities in for AEM Assets.
Transcript
In this video, we are going to be discussing about Dynamic Media Color Management introduced in AEM 6.3.
This feature is also available for AEM 6.1 and 6.2 users as a feature pack.
Once you’ve installed the feature pack you need to configure the appropriate default color profiles to any available color correction when requesting RGB or CMYK data. To configure the different color profiles Go to CRXDE Lite, click on ETC, click on dam, image server, configuration, jcr.content, and settings.
Along with the feature pack solution, a list of color profiles can also be found under profiles. We can also add a color correction property by clicking on the settings option and scrolling down to the bottom of the properties tab and providing the property .name, type, and value. A list of color correction property and its values can be obtained from the Configure Dynamic Media documentation page. Select a color correction value that you would like to assign to your media server settings. Let’s select the ICC profile src grey. Let’s go back to CRXDE Lite and copy paste the value here under name, provide the type as string and provide the value of a color profile. Let’s go to the profile section from the list of color profiles and let’s select the apple RGB value and paste it here in the value text field. Once you’ve added the name, type and value for your color collection property, click on add option and click on save all. Let’s go back to the previous tab. Click on the Adobe Experience Manager logo and from the navigation select assets. Open the folder where you have the desired assets stored, click on the image and open it to check the asset details. By default the color profile for this image is in RGB. We have three image presets created for different relations with three different color profiles, RGB, CMYK and grayscale are the three color profiles available for rendition.
Click on the CMYK color profile and you can notice the change in image rendition.
Now the image has more of a green or yellow shade compared to its original image.
Let’s switch to a different image preset and see the difference in the image rendition.
The original image was an RGB color profile and now we have created different renditions for the original image with different color profiles in order to match the target device’s color profile. For an image created with a different rendition you can view the properties of an image by simply right clicking on the image and open the image in a new tab.
The URL and the following parameter requisite is equal to properties and you should be able to see the properties of this image.
