When using EditLab to create an ICC profile, you are actually saving the color correction function into an ICC input profile in such a way that when the profile is assigned to an image, the same correction occurs. As we have just learned with profile editing, one must be careful when working with ICC profiles in general. Here is a step-by-step procedure for saving an edit as an ICC profile:
1. Open your image in Photoshop
In order for EditLab to work properly for creating profiles, the image must be in the current RGB working space. Using an assigned profile instead of the working space will not work! If your image has an embedded profile, you should first convert to the working space before using EditLab.
2. Run EditLab
Use EditLab to make whatever changes you like.
You may wish to enter a name in the "ICC Name" field.
A General Note on Profile Naming: When an application displays the "name" of an ICC profile (for example, in a pop-up menu of profiles), it often uses the profile's Profile Description Tag, which is a description found inside the profile file. This means that the file name given to the ICC profile might not be used — an observation that may surprise you. Therefore, if you rename the ICC profile file at a later time, you may not see that change reflected in applications which use the internal Profile Description Tag instead.
You are given the opportunity in EditLab to enter whatever text you want for the internal Profile Description Tag:
Anything you type in this field will be placed into the Profile Description Tag inside the ICC profile. If you leave this field blank, EditLab will automatically insert the name you give to the ICC profile (without its extension).
Click the "Create Profile…" button.
3. Save the Edit as an ICC Profile
You will be asked to provide a name and location for the profile.
4. Using the ICC Profile
You use the profile by assigning it to images when you open them in Photoshop.
