Known for its vibrant colors, Kodak Ektachrome debuted in 1946 and disappeared in 2012. It's back. First for 35mm, and later this year for Super 8 and 16mm formats, the slide film is once again available. Made from 106 components spread across 15 layers, it's also known for its easy development process, as it carries its own pigments. Its signature blue-hued images were made famous by National Geographic photographers and the astronauts who carried it to the moon, and now you can capture your own memories on the same medium, assuming you still have a film camera lying around.
