Like most I enjoy old B&W photography, its a window into the past and adding color to them can add a new dimension to an already interesting image. On this page a series of old Sydney mugshots from the Police and Forensic archives that Ive colorized. More of these amazing images can be seen at the Sydney Living Museum website.
Now its not as simple as it may seem, to get the skin right you cant just paint a brownish pink over the face and blend it down, you need to create multiple layers of varying colors, for example skin around the face has layers of fat around the cheeks, neck etc these appear slightly yellow, ears and nose have a reddish tinge due to blood vessels being closer to the top of the skin, parts of the skin may be darker due to more sun exposure, you really need to get the bioligy down, also direct light will make skin seem desaturated. Its a fine art that Im hoping to improve on over the years.
