Colorizing black and white images is a very old technology. It began with the desire to correct early "colorless" photographs manually. When color photography was still not common, it was necessary to give a helping hand to obtain a color picture that looked photographic. These early colorations are often technically very well done and in some pictures you really have to look twice before you discover the hand-painted color.

Sometimes the combination of old and new gives surprising results. There are some fantastic lenses from the analogue days, which can be easily connected to modern digital cameras with adapters. One of these is the Russian portrait lens Helios 40-2 85mm F1,5. There is a lot of technical information about Helios available on the Internet; I give you some usage tips based on personal experiences.
