Sometimes the colors in your image aren’t quite right and it’s not all of them but perhaps one in particular. White balance, saturation and vibrance adjustments affect the whole image, so how do you target specific colors? In Lightroom it’s easy.
A special effect which converts the whole image into black and white except for one specific color range. One the the most common examples is a black and white image with a bright red subject – the girl in the red coat in the film ’Schindler’s List’, for example.
