Photography. From the time the first image was captured almost 200 years ago, people have been using photography techniques to record, improve and expand their world. Joseph Nicéphore Niépce is credited with capturing the very first photograph—a view of outside his window—using a technique called heliography. From that blurry, one-of-a-kind print to the stunning images captured today we can capture using our mobile phones, the advances in personal photography have been phenomenal. But progress has not been limited to capturing images of the world we see, scientists have leveraged these advances into new tools to capture images of the world we can’t see.
