The polarizer effect allows you to create a nice blue sky. This effect is not suitable for every type of photo but can be used best for photos with large areas of light sky
By selecting this effect it will open the settings dialog where you can set its parameters.
Use the slide to define where the blue sky should end. IDimager will apply the ôblueö only to the light areas so if dark areas overlap with the light areas, these will not be polarized.
