The very first photo ever taken in 1826 took a whopping 8 hours to expose! But by 1839, Louis Daguerre had made huge strides and cut that time down to just 15 minutes.
It's amazing how quickly photography advanced! The first photo's 8-hour exposure time seems almost inconceivable today, but Louis Daguerre's 15-minute improvement in 1839 was a huge leap forward.
