The steps involved in the colorization of an old black and white photo are given as follows:
Clean the image
Adjust the image’s contrast and tone
Convert the image to CMYK
Colour the Image
Explanation:
Cleaning the image has to do with removing dust and scratches. This can be executed manually or automatically
Adjusting the image involves removing the tones. This is achieved by adding layers. Layers must be black and white. To adjust the contrast, the Levels adjustment layer is then added. Finally, for this step, the shadows must be darkened.
Converting the image to CMYK helps to colorize the dark portions of the photo better.
