Your camera may have the option to trigger off-camera flashes using the built-in pop-up flash. It’s a system that works wirelessly, but not by radio signals. Find out how the camera’s optical trigger is able to communicate to external flashes in this self-proclaimed super-duper nerdy video.
It's easy to take for granted the fact that our camera sensors somehow translate light into digital data that is eventually reconstructed as a viewable image on our monitors when we return to our studios. However, there's some very deep and impressive science behind this feat, and this neat video will introduce you to how it all works.
Most of us know about the exposure triangle, which dictates how shutter speed, aperture, and ISO balance each other to create the total exposure. But rarely if ever do we dive deep into what exposure really is at the fundamental level. This great video will give you a fun, scientific breakdown of exposure and metering.
We talk qualitatively quite a bit about the softness or hardness of light, as it's one of the fundamental qualities and something every photographer and videographer should consider when choosing how to light their subjects. This neat video takes a more scientific approach by asking how we can quantify the softness of light.
In what could be called a coincidence of cosmic proportions, an amateur astrophotographer from Argentina (say that three times fast!) has, for the first time, captured a spectacular space phenomenon on camera against nearly impossible odds, as reported by LiveScience.com.
The Internet can take you to places that you might never get to see in person such as the famed astronomical clock in Prague’s Old Town Square or the Amundsen–Scott research station in Antarctica. And, there are cameras situated at literally the top of the world capturing things in the night sky that you may have never even seen before.
Chances are you've seen historical footage from NASA at some point in your life, whether in a movie, on television, on the Internet. That footage was extremely hard to film, however, and this great video examines the technical challenges behind shooting rocket launches and space.
