How to Colorize a Black And White Photo in Photoshop
Create a New Layer
The first crucial step that most photo editors miss out is to create a new layer from the source image. Well, this step is vital because it enables you to retain the original copy of the image should anything go wrong. Next, you can use the layers masks to edit and add the colors you want to every part of the photo.
Remove Scratches and Dust
In a case where you are working on an old image, the next step will be to clean it up. You can attain the best results in this step by initiating simple adjustments to the Threshold and Radius levels until when you will clear out the flecks. If this method does not give you the results that you want, you can create a layer mask to paint over at any point where there are flaws.
Adjust Contrast and Neutralize the Color
In a case where the photo you want to edit features the sepia tone, you can add the black and white tone to neutralize it. Next, you will use the levels adjustment layer to edit the contrast.
You can also add color to the photo using the Curve adjustment option. In this case, you will choose the color you would like to adjust by adjusting the yellow, magenta, and cyan curves.
