Photographer Mathieu Stern recently found a time capsule inside his old family home and discovered two glass plate negatives inside

The man estimates that the time capsule is most likely over 100 years old

After his last YouTube video, a family member told him that there could be a time capsule hidden in their old family home. And lo-and-behold - there actually was!

There were all sorts of little trinkets inside but it was the two glass negatives that caught the photographer's eye

He used the cyanotype process to develop the negatives

“After investigation, I found a box dating from around 1900 judging by the objects and the technique of the photos found inside," said the man in his latest video. "So I decided to develop the images using the Cyanotype Process.”

First, Mathieu covered a piece of paper with cyanotype solution

Then the man secured the glass negative on the paper covered with cyanotype solution in a wooden frame

The framed setup was placed under a UV light and developed for about half an hour

Then the photo paper was soaked in water and finished off with hydrogen peroxide

And voilà! - a 120-year-old cat photo right before your eyes

Mathieu later colored the photo using Photoshop
