CT Correction

Note: Roll your mouse cursor over the effects names above to see the indicated PhotoKit Color effect.
The CT range of effects provide a means to warm or cool a photograph in varying amounts. The CT stands for 'Color Temperature' and these filters aim to match the light filters which go by the same name and use the same increments as shown here. These filters are no substitute for using the white balance controls in Camera Raw to adjust the white balance of a raw shot image, but they do provide a means in Photoshop to apply a warming/cooling type of color correction.

RGB Workspaces
The above film effects are precision adjustments and are dependent on the RGB space of the file you are working on. PhotoKit Color 2.0 is able to detect and recognize the following RGB spaces: Adobe RGB, Color Match RGB, ProPhoto RGB and sRGB. The effect applied will be tailored to match the RGB space the file is in. If you are using some other flavor of RGB, PhotoKit Color will default to applying the Adobe RGB effect.
