Are the Mirrors Inside DSLR Cameras Ever-So-Slightly Green?

You know the infinitely long tunnel that appears when you look into two mirrors that are pointed at one another? Have you ever noticed that the tunnel becomes more and more green, the deeper you go?

YouTube personality Vsauce has a fascinating new video titled "What Color Is A Mirror?". In it, Mr. Sauce explains that this is due to the fact that there is no such thing as a perfect mirror (i.e. a mirror that perfectly reflects 100% of light). The fact is, a typical mirror best reflects light in the 510nm range, which we perceive as green light.

Using a Face Detector to Generate Creepy Mugs from Random Polygons

The man in the moon and the face on mars. These are both the result of a psychological phenomenon known as pareidolia, which involves the brain trying to perceive random signals as significant. It's one of the brain's face detection mechanisms, and causes us to see faces where they don't actually exist -- the Virgin Mary's face on toast, for example.

Programmer Phil McCarthy decided to play around with the idea of paredoila in artificial intelligence, and created a program called pareidoloop. It uses face detection algorithms to "see" human faces in randomly generated polygons.

What It Feels Like to Be a Freelance Photographer

Freelancers often have to deal with the difficult challenge of trying to satisfy vaguely stated requests from clients, and also the frustration of meeting new requirements that aren't revealed until after the work is "completed". The video above is an interesting social experiment by Don't Get Screwed Over that attempts to show people what these freelance horror stories feel like to the people getting "screwed over".

Common Photography Mistakes Made by Beginners Back in 1902

Why My Photographs Are Bad is a photography book for beginners first published in 1902 by a man named Charles Maus Taylor. The book contains many of the same basic tips that can be found in introductory books these days, but also many that are very specific to the way photography was done at the time. Here's a selection of common mistakes that newbie photographers were making over 100 years ago.

Camera Obscura Images Can be Collected From Any Windowed Room

The camera obscura has been around for a long time (Middle Ages long) and typically consisted of a box or room with a hole in one side through which an image of its surroundings could be formed. As you can see from the example above, any room -- in this case a bathroom -- can be turned into a camera obscura given a small enough "aperture." Unfortunately, most rooms have big, blaring windows that let in too much light, and the only image formed on the opposite wall is a shadowy blob.

In the name of forensics, however, Antonio Torralba and William Freeman from MIT have discovered a technique by which they can turn any windowed room into a camera obscura, using a couple of stills of the room to magically gather an image of the outside world.

The Uncropped Versions of Iconic Photos

Here are some uncropped (or "unzoomed") versions of iconic photographs that show more context than their famous cropped counterparts. It's interesting to see what photographers and photo editors chose to keep and what they chose to throw away. The image above is an alternate view of Tank Man.

The First Photographs of US Presidents

Here's your interesting piece of photo trivia 'o the day: John Quincy Adams, the sixth President of the United States, was the first president to have his photograph taken (the earliest photo still in existence, at least). The daguerreotype was shot in 1843, a good number of years after Adams left office in 1829.

10 Photographers You Should Ignore

Editor's note: This is a piece by photographers Bryan Formhals and Blake Andrews on how famous photographers' styles are copied over and over again. Please do not read or comment if you take things too seriously.

The other day while reading the Internet I came across “The 10 Most Harmful Novels for Aspiring Writers.” I wondered whether there could be a list for photographers as well. I thought about it and then sent my list to Blake Andrews to see if he wanted to contribute and have some fun with it. Here's what we came up with.

Documenting the Human Condition: A Documentary on Street Photography

Here's an oldie but goodie: back in September 2009, photographer Chris Weeks released this documentary about street photography titled Documenting the Human Condition. It's occasionally preachy and at times feels like a stealthy Leica advertisement, but should be interesting to you if you're at all interested in the practice of street photography.

Auroras, Meteors, and Photography from the International Space Station

Here's a fascinating video by NASA that explains what auroras are and what they look like from space. It's filled with beautiful photographs and time-lapse sequences captured by astronauts on the International Space Station. Astronaut photographer Don Pettit, who maintains a blog about his experiences, writes that taking pictures of Earth is harder than it looks.

Albert Kahn’s Documentation of Humanity Through Early Color Photography

Albert Kahn was a wealthy French banker who launched a project in the early 1909 that aimed to create a photographic record of the world. The first commercially successful color photography process, Autochrome Lumière, had just arrived two years earlier, and Kahn decided to use the medium to both document human life and to promote peace. He sent out an army of photographers to 50 different countries, amassing 72,000 photos and 100 hours (183,000 meters) of film that became one of the most important collections of images in human history.

Viral Photographs Bring Instant Success

Photographers used to spend lifetimes building up their portfolios and networks before their work became widely known to a global audience, but with the advent of the Internet, the fact that anything can "go viral" is completely changing the equation for success.
