demonstration

While teaching a street photography workshop in Chicago recently, photographer Chuck Jines saw an opportunity to teach his students how he's sometimes able to shoot portraits of strangers from extremely close distances without them noticing.

"I had the opportunity to demonstrate just how much a photographer can get away with when people are lost in thought or occupied with a task," Jines says. His unusual demonstration is seen in the 1.5-minute video above.

Want to see what a 10K time-lapse video looks like? Look no further than the video above. Titled "10328x7760: A 10K Timelapse Demo," it was created by Los Angeles-based photographer Joe Capra, a guy who specializes in ultra-high-definition time-lapse photography.

If you don't have a 10K display handy, don't worry: the video zooms in to show you the level of quality the video has.

Schlieren flow visualization and photography is one of those things that is just too cool. Using an optical trick, it allows a camera to capture, "small changes in the index of refraction in air." In other words, it can see anything that affects airflow: heat, sound waves, or just plain old air currents themselves.

And the video above, uploaded at the beginning of this year by the Harvard Natural Sciences Lecture Demonstrations YouTube channel, is one of the most fascinating demonstrations of Schlieren optics we've ever seen.

A UK-based amateur photographer named Bob Riach was stopped outside a shopping center in East Yorkshire last week by a security guard. Riach was attempting to take some nighttime shots of the complex when the guard confronted him and told him that his photography wasn't allowed due to the complex, citing concerns of an attack by ISIS.

This week a group of photographers decided to stage a protest in support of Riach and photographers' rights.

At Photokina 2014, Sony is a showing off its new autofocus technology called "4D Focus." It's an AF system that blankets the scene with a wide coverage area and can rapidly focus on subjects while predicting their movements over time.

Earlier today, Adobe announced a collection of upgrades, updates and new releases for its Creative Cloud platform. Briefly detailed in our coverage of the announcement, Photoshop CC received a number of improvements, Lightroom Mobile received an iPhone version, and Adobe announced a new iPad app Photoshop Mix.

But that was just an announcement, and so to properly introduce you to a number of these features, we’ve compiled a demo/walkthrough collection that shows each of these new features and apps in action.

Most lenses nowadays come with a multipurpose chemical coating, meant to not only protect the lens a bit more from accidental scratches, but to also reduce reflections and aberrations and provide a clearer image. How the coating actually works might be a mystery to many of us though.

With only a 12-megapixel sensor and ISO expandable all the way up to 409,600 for both stills and video, everybody knew that that the Sony A7s was going to be a low-light beast... and yet the performance is still taking us by surprise.

Yesterday a short demo video shot at NAB was shared online to a plethora of "oohs" and "aahs," and today, the Sony How To YouTube channel released yet another mind-blowing demonstration of the camera's night-vision capabilities.

The introduction of the new Perspective Warp tool (among other things) for Photoshop CC was met with a good deal of excitement by photographers. But if you haven't had a chance to play with it yourself, or you're still unsure exactly how it works from the intro video, the demo above should give you a much better idea of how to put the tool to use.

Earlier this month, Canon announced that there's a firmware update for the Canon EOS M on the way that will boost the mirrorless camera's sluggish autofocusing speeds by up to 2.3x. Given that AF slowness is one of the biggest gripes EOS M owners have with the camera, the news was likely music to many a EO M owner's ear.

If you want to see what this 2.3x looks like in real life, Korean photographer Daero Lee has published a number of comparison videos showing updated and non-updated EOS Ms focusing on things.

When Fujifilm announced its latest wave of X-Series cameras earlier this year, the company stated that the big area they're focusing on is "speed". The new X20 and X100s feature extremely speedy autofocus, burst speed, and startup time. The 's' in X100s may officially stand for "speed," but it could just as well stand for "silent" or "stealth". Both cameras feature extremely silent shutters that won't attract attention while you're snapping away.

The video above by nycphotog2006 shows how silent the X20 is even while the leaf shutter is fluttering at a staggering 12fps.

When Fujifilm announced the X100s last week, it made the bold claim that the camera had the world's fastest autofocus system among cameras of the same class. Sluggish autofocus was one of the big complaints owners of the X100 had, so for this latest refresh the company focused its attention on making the camera faster.

Want to see how fast the new AF is? We captured the short video above during a brief hands-on time we had with the camera. It doesn't show an in-depth test or much variety in subject matter, but should offer a taste of what "world's fastest AF" looks like in the flesh.

Here's a quick demonstration of what Fujifilm's new focus peaking looks like on the freshly-announced X100s and the X20. When manually focusing the lens, the feature uses white pixel highlights to indicate the high contrast areas of the scene. This is one of two new features -- the other being split image focusing -- designed to make manual focusing a much nicer experience on X-Series cameras.

We were just able to get some hands-on time with the new Fujifilm X100s immediately after the company's press conference. In addition to blazin' fast autofocus speed, the company has also introduced a couple of new features that manual-focusing photographers will love.

One is something many photographers are already familiar with (and have been clamoring for): focus peaking. The second hasn't been received with as much fanfare, but is actually quite fantastic. It's split image focusing -- something rangefinder users will appreciate very much.

If you've never shot with an old manual focus film SLR, you've probably never experienced the joys (and pains) of focusing with a split screen and microprism ring. YouTube user ttcalan created this short video that demonstrates how the system looks and works. He writes,

Just a demonstration of how manual focus works on a Minolta X-700. It's shot through the viewfinder and shows how the split prism and microprism ring help the photographer focus. I also show how stopping down the lens causes the split prism to go dark.

At The Impossible Project's booth at Photokina 2012, there was a Impossible Instant Lab camera printer/camera being demonstrated. This is the device that was announced a couple of weeks ago that lets you quickly turn your iPhone photos into Polaroid pictures (i.e. Impossible's instant film or whatever stock you have left).

Nokia has endured a torrent of bad press over the past couple days over its faked promo video, but the truth is, the company is investing heavily in improving photography in its mobile phones, and its PureView technology is definitely something we should be keeping our eyes on.

In order to back up its claim that PureView low light performance is "unbeatable", Nokia set up a "photo challenge" booth at its launch party and invited passers-by to pit their cameraphones against the Lumia 920. The challenge involved shooting a photograph of a still life setup stuffed inside a dark cubby hole in a brick wall. Check out the video above for a glimpse of how the phone's camera stacked up against the iPhone's and the Samsung Galaxy's.

In daguerreotype photography, the first commercially successful photographic process, a positive image is recorded directly onto a silvered copper plate. Although mercury is traditionally used to develop the plate, there's a way of creating daguerreotypes called the Becquerel method that eschews mercury in favor of non-lethal ingredients.

A recent fad in advertising is to use 3D projection mapping on buildings at night to create jaw-dropping effects. The above video shows an ad Samsung ran on a historic building in Amsterdam to promote the Samsung 3D LED TV. A perfect representation of the building is first projected onto the actual building, and then mind-blowing things begin to happen.

Adobe is working on a new feature for Photoshop called "Content Aware Fill", and posted a mind-boggling demonstration of it on YouTube.
