Selective color is a post-processing technique where most of a photo is converted to black and white, but some parts are left in color. The reason for this is simple…sometimes it just works. I shot this image of my daughter walking down a nearby pier on a stormy day. My initial goal here was to place emphasis on the sky. However, she had this pink umbrella in the car with her and I noticed the potential for strong contrast of the “dreary” day and bright umbrella for this image. The image was originally shot in color, later a copy of the original image is made in Photoshop and processed into a black and white. Now you have two images one color and one black and white. Stack them on each other using layers placing the black and white above the color image. Now you have to “carefully” erase the black and white layer from the umbrella to reveal the color of the bottom layer below. After your done you merge the two layers into a single image.
