Whether you are old enough to remember them, or you have just noticed them while sorting through old family photos, you may be curious how the small glowing date was printed on photos & # 39; s in the late 20th century.
In the age of digital photography, the small orange date stamp in the lower right corner of snapshots has largely fallen out of the way. However, the technology used to superimpose the dates on old photos is pretty cool ̵
In this video from Applied Science we are treated to a tour through an old camera housing. You will see how a little extra in the body made it possible to add the date to a negative photo when it was taken.
Pretty cool! We like to find out how things work – even more so when how they work is so simple and elegant.
