There are countless videos and forum threads discussing and debating about the principles of crop factor, depth of field, and sensor size. However if you are the type to geek out over the math and physics of photography then this is the video for you. This is no simple examination, at 35 minutes long it requires some advanced knowledge on camera sensors.
Microscopes allow us to peer into the tiny worlds hidden from our naked eyes, but tracking slowly evolving movement with them can be a logistical nightmare. Scientists have developed a new technique for automatically tracking movement and locking focus, creating spectacular time-lapses in the process.
At this point in our lives, the majority of us have come to understand our capabilities and our limitations. If we were never good at sports, we have come to accept this as truth. If we are great at math, we have likely received this "gift" and possibly moved into a career field where we can maximize the ease of which numbers have come to us. As photographers, you have the "eye" for it, or you don't. Are these established beliefs, based likely on past evidence in reality, or are they limitations we have placed upon ourselves?
Ah, the crown of the (Ant)arctic. Known in the northern hemisphere as the Aurora Borealis (northern lights), and as the Aurora Australis in the southern hemisphere, these brightly colored bands of moving and waving light are a majestic display in the night sky. Who doesn't want to take a picture of this otherworldly phenomenon? Here's exactly how to do it.
We've all heard of sonic booms, which occur when the shock waves produced by an object traveling faster than the speed of sound accumulate to produce a giant pressure wave, but what about "photonic" booms? Researchers have just shown that indeed, light exhibits the same effect, and they used a camera that records 100,000,000,000 frames per second to show it.
"NASA Supercomputer" and "DJI Phantom 3" are not words I ever expected to hear in the same sentence. Nonetheless, using advanced computer analysis, the agency has created this simulation of a drone's aerodynamics to help design better models in the future. It's pretty neat to watch.
When guests aboard the International Space Station look for a place to escape for a little rest and relaxation, options can obviously be limited. The “Cupola” was built in 2010 to provide astronauts with the best view possible while operating the ISS’s Mobile Services System’s robotic arm (the Canadarm2). The Cupola's seven bay windows allow for an incredible view that's become a favorite for photographers aboard the ISS. Russian Cosmonaut Andrey Borisenko brings us inside the Space Station’s observational dome with the first 360-degree 4K video of Earth from within the International Space Station.
Earlier this week, the largest moon of almost 70 years could be seen around the world. This "supermoon," as it is being hailed, occurred after it appeared 222,000 miles from Earth — to put it into perspective, that's some 30,000 miles closer than the most distant point it ever pops up. According to NASA, that caused it to appear 14% bigger and 30% brighter than what we’re used to. Naturally, photographers everywhere were out in full force trying to grab the best photo. But one image in particular is garnering attention after making NASA’s Astronomy Picture of the Day.
