This article discusses the history and process of colorization, a technique used to add color to black-and-white images. The first colorized film was The Wizard of Oz (1939), and the process has been used on a variety of films since then. While some people view colorization as a way to preserve history, others see it as a form of vandalism.
There are a few companies that offer colorization services. To colorize an image, they first need to convert it to black and white. They then use a software to add color to the image.
Overall, colorization services can be a great way to bring new life to old photos. If you're considering having some photos colorized, be sure to do your research and choose a reputable service. Also, keep in mind that colorized photos are not necessarily "true" historical records - they are more like interpretations of history.
