Whether you're old enough to remember it or just noticed by sorting out old family photos, you may be curious to see how the dazzling little date was imprinted on the pictures of the late 20th century.
In the era of digital photography, the small orange date stamp in the lower right corner of snapshots has largely disappeared. However, the technology used to overlay dates on old photos is pretty cool – and surprisingly low-tech.
In this Applied Science video, we are seeing an old camera. You will see that a little more in the body allowed to add the date to a negative photo at the moment it was taken.
Pretty cool! We like to discover how things work, even more when their operation is so simple and elegant.
