Change Profile

This transformation associates a new profile with an image and transforms the image’s colors from its current to its new profile. You can change either on the input profile or the output profile or both and can recalculate the image’s colors or simply change the assigned profile without changing the image itself. There are circumstances under which each option is appropriate. To correctly view the results of profile changes, color management must be enabled.

Input Profile

Determines whether or not to use the current input profile. The options are:

Retain current -- Retains the current input profile – this is the most common setting. The name of the current profile is shown below the control.

Set to custom -- Resets the input profile to the profile you select. This setting is used when the originally assigned input profile is incorrect. For example, if the image originates from a device (scanner or camera) that has been profiled, you can use this function to assign the calibration profile to the image.

Output Profile

This control lets you select the name of the profile you want to change the image to use.

You will get an error message if you attempt to change the profile to None or to a scanner profile unless you are just re-tagging the image with the new profile by setting the Change control (see below) to Profile Setting Only. The color management engine does not support changing image data to these profiles. Instead of None, you should select sRGB IEC61966-2.1 which is the default profile. It does not really make sense to transform image data to a scanner profile as a scanner is designed for input, not output.

Rendering Intent

This control lets you select the rendering intent to use when transforming the color data from the input image to the output image. Maintain Full Gamut is the most common setting for photographs. For more details on rendering intents and when to use them, see the Color Management white paper.

Change

This control lets you select whether you want to change both the image data its associated profile or just change the image data or the profile.

Image Data and Profile -- The image data is translated to the output color space and the output profile is assigned to the output image. This is the most common setting and will generally cause minimal color shifts.

Image Data Only -- The input image data is translated to the output color space but the original profile is assigned to the output image. This will usually cause a color shift – if changing to a color space with a wider gamut, the image will look less saturated and vice versa.

Profile Setting Only -- The input image data is copied unmodified to the output image the new color profile is assigned to the output image. This will usually cause a color shift – if changing to a color space with a wider gamut, the image will look more saturated and vice versa.
