VIETNAM IN COLOUR

I noticed that on your magazine website you have reprinted a feature on American uniforms in the Vietnam war that previously appeared in the magazine. However, not only have the images been colourised but there's also a video at the bottom of the article that shows two of the people in the photos blinking and smiling! I wondered how this was achieved?

Ed says: Colour and animation were added to put something new into the online feature (but how we did it is a secret!)
