Today, I'd like to dive into the use of shadows in landscape photography. Shadows are almost always part of nature: we often shoot using a (almost-)point light source (the sun or the moon), and even ...

In a discovery that challenges conventional optics, scientists have managed to make a laser beam cast its own shadow—a feat previously thought impossible, as light typically passes through other light ...

A team of scientists has found that the narrow beam of a laser, under specific conditions, can cast a shadow — a counterintuitive finding that could open the doors for new applications of optical ...
