Man Develops 120-Year-Old Cat Photos Found In Time Capsule

Can you imagine developing photos that are 120 years old? YouTuber Mathieu Stern did just this after discovering an old, family time capsule from the year 1900. The time capsule contained two glass plate negatives which he decided to try and develop on his own. He used the Cyanotype, which is one of the oldest photograph printing methods to date.

“Because of my last video, someone in my family told me about a possible time capsule in our old family house,” Stern writes on his blog. “After investigation, I found a box dating from around 1900 judging by the objects and the technique of the photos found inside. So I decided to develop the images using the Cyanotype Process.”
