how to change light of a photo in photoshop
0. Sometimes in post production you will want to change the colors of an object in your photos. Photoshop has a number of tools that you can use to change the color in an image, and in this post Iâll show you some of these which you can use without having to make a selection on the image.Before I begin, a word about the photographs Iâm using.his tool works well when you have an image such as this one where most of the color that you want to change (the reds) only appear in the area that you want to change and not elsewhere in the image. To change the color, drag the sliders to add more of the colors you want to add and to remove the opposite color.
