If you stop and think about it, it's pretty difficult to exist in today's world. Vaccines are(n't) out to get your children, there could be Daleks around every corner, and even that vintage lens you scored on eBay might be radioactive, lurking between the sheets, following your every move, wreaking havoc on your DNA when you're not looking. Maybe even stealing your french fries. Or, at least that's what Mathieu Stern was concerned about before he made this video.
Our biological instincts are so hard-wired when it comes to the perception of attractiveness that we're actually quite predictable in our choices, even if we can't explain the reasons behind them. Thankfully, science has delved into these unconscious tendencies, and its findings can really help give our portraits extra sex appeal.
There's a lot of discussion around having a camera out constantly during experiences. And while the etiquette of it is one question, a recent study shows that taking pictures of enjoyable events does indeed increase one's positive experience of them, as long as a few conditions are met.
Not too long ago, using autofocus in video was slow, unreliable, and generally unacceptable. Companies have been working to make it viable for filmmakers, with Canon's solution being Dual Pixel CMOS Autofocus, which has generally been lauded for its performance. Here's a neat, short video on how it works.
Machine learning is an incredibly powerful thing. Damien Henry, a technical program manager at Google, took advantage of this, feeding a machine learning algorithm a single image and asking it to generate an hour-long video of approximately 100,000 frames by predicting the next frame based on the previous one. The result is gorgeous to watch.
You think your camera is fast? Check this out. A group of researchers at Lund University in Sweden have developed a camera that is way faster than yours. I guarantee it. Their camera captures at a frame rate equivalent to five trillion images per second, a rate faster than previously thought possible. It’s so fast that even captures light in flight.
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.
