Photographic toning is a tool that is not widely used by Photoshop users and the reason for this could be because users are unfamiliar with the usage or they probably just didn’t know it even existed. Photographic toning is used for tinting and split toning images for better results. Photographic toning is great because its based on real world chemical processes.
