Whether you're old enough to remember them, or you've just noticed them browsing through old family photos, you might be curious how the little date lit up at the end of the 20th. Century imprinted on photos.
In digital photography, the small orange date stamp in the lower right corner of snapshots has largely fallen by the wayside. However, the technology that overlays old photos with dates is pretty cool ̵
In this video from Applied Science, we are confronted with a tour of an old camera body. You will see how a little bit more in the body made it possible to add the date to a negative photograph the moment it was taken.
Pretty cool! We love to figure out how things work – especially when their workings are so simple and elegant.
