As the low-light capabilities of high-end (and even low-end) cameras rapidly improve, it’s easy to marvel at technology and forget how amazing our own eyes are, but here are some mind-boggling facts to consider: did you know that the human eye can detect as few as two photons entering the retina, and that, under ideal conditions, a healthy young adult can see a candle flame from 30 miles away? To see how mind-boggling that is, try using Google Maps to find a location 30-miles away from where you live.

According to neuroscientist Bradley Voytek, the reason we don’t utilize our full sensory potential is because we’re not paying enough attention to them — kinda makes you want to put down your camera and focus on staring at things, huh?

Color photography was born on this day 150 years ago in 1861 when Scottish physicist and mathematician James Clerk Maxwell and photographer Thomas Sutton — inventor of the SLR camera — shot the above photograph of a colored ribbon.

[...] Maxwell proposed that if three black-and-white photographs of a scene were taken through red, green and violet filters, and transparent prints of the images were projected onto a screen using three projectors equipped with similar filters, when superimposed on the screen the result would be perceived by the human eye as a complete reproduction of all the colours in the scene.

During an 1861 Royal Institution lecture on colour theory, Maxwell presented the world’s first demonstration of colour photography by this principle of three-colour analysis and synthesis, the basis of nearly all subsequent photochemical and electronic methods of colour photography. Thomas Sutton, inventor of the single-lens reflex camera, did the actual picture-taking. He photographed a tartan ribbon three times, through red, green and blue filters. [...] Because Sutton’s photographic plates were in fact insensitive to red and barely sensitive to green, the results of this pioneering experiment were far from perfect. [#]

Thus began modern color theory and the fundamentals behind how your DSLR captures color.

Dutch consumer product website Beste Product (“best product”) decided to set up a royal rumble between the two heavyweights of the camera industry: Canon and Nikon. They created an infographic comparing the two companies in things such as expert and user opinions, popularity, and sales. Even if you’re sick and tired of the endless comparisons and debates (as you should be), the infographic provides some interesting facts about how the two companies are doing.

When learning about ISO, you’ve probably heard that the lower the number, the lower the noise and the higher the image quality, but did you know that this isn’t always the case? The reason is something called the base (or native) ISO of a camera — the ISO achieved without amplifying the data from the sensor. This is usually somewhere between ISO 100 and ISO 200. Why does this matter? Bob Andersson of Camera Labs explains:

We all know that using high ISO numbers results in more sensor noise. More surprising, perhaps, is that using an ISO number below the native ISO number also degrades the image.

An interesting example is that when shooting on a Canon EOS 1Ds MkII, ISO 50 has roughly the same signal to noise ratio as shooting at ISO 800. This explains why the lowest possible ISO numbers can only be accessed through custom functions on some cameras.

Did you know that the first digital camera invented in 1975 didn’t actually produce the first digital photograph? The first digital photo actually came almost two decades earlier in 1957 when Russell Kirsch made a 176×176 pixel digital image by scanning a photograph of his three-month-old son. The low resolution was due to the fact that the computer they used wasn’t capable of storing more information.

This photograph of Boulevard du Temple in Paris was made in 1838 by Louis Daguerre, the brilliant guy that invented the daguerreotype process of photography. Aside from its distinction of being a super early photograph, it’s also the first photograph to ever include a human being. Because the image required an exposure time of over ten minutes, all the people, carriages, and other moving things disappear from the scene. However, in the bottom left hand corner is a man who just so happened to stay somewhat still during the shot — he was having his shoes shined.

Here’s a fun bit of trivia: did you know that at one time Apple (then named Apple Computer) made compact digital cameras? Launched in 1994, the Apple QuickTake was actually one of the first digital cameras available to consumers. Three models were built by Kodak and Fujifilm, and the cameras boasted a whopping 0.3 megapixels and the ability to store eight photos at this resolution. The camera had a flash, but lacked zoom, focusing, image review, and file deletion (the entire contents had to be wiped).

If you’re a digital photography buff, here’s some required trivia knowledge: what you see above is a photograph of the first digital camera ever built. It was created in December 1975 by an engineer at Eastman Kodak named Steve Sasson, now regarded as the inventor of the digital camera. In a Kodak blog post written in 2007, Sasson explains how it was constructed:

It had a lens that we took from a used parts bin from the Super 8 movie camera production line downstairs from our little lab on the second floor in Bldg 4. On the side of our portable contraption, we shoehorned in a portable digital cassette instrumentation recorder. Add to that 16 nickel cadmium batteries, a highly temperamental new type of CCD imaging area array, an a/d converter implementation stolen from a digital voltmeter application, several dozen digital and analog circuits all wired together on approximately half a dozen circuit boards, and you have our interpretation of what a portable all electronic still camera might look like.

The Washington Post just published an interesting article called “Pros and cons to Facebook’s fast-growing role in digital photography“, which contains quite a few interesting statistics. Among them,

• 40% of households with digital cameras no longer make prints
• 65% of people sharing photos online do it through Facebook
• Less then 33% of people realize that Facebook stores photos at a decreased resolution

The last statistic is quite startling. It means that we may have a whole generation of people who are essentially “throwing away their negatives” after “making very small prints”.

Facebook doesn’t have the capacity to store all the world’s photos without shrinking them first. Facebook just announced that it will increase its maximum photo size by 20 percent. But even with the upgrade, the photo quality on Facebook isn’t useful for more than basic onscreen viewing.

[...] It’s also troubling that most users aren’t aware that uploading a picture to Facebook — and then deleting it from your camera — means you’ve lost the original image for good. [...] This is probably because Facebook photos look just fine on a computer screen.

Remind your friends and family to keep all their original image files. Otherwise, they might need higher resolution versions in the future but find themselves stuck with 720px.

Nikon recently conducted a survey called “Picture Yourself”, and released some interesting findings today, a lot of which reveals things about the way people view themselves. The survey was conducted using random telephone dialing, and sampled 1000 Americans 18 and older.

If only we had thought of some of these questions for our weekly polls… Maybe we’ll use a few in the future.

Anyhow, here were some interesting findings:

• 25% would choose to retake a family photo if they could turn back time
• 92% of adults had at least one photograph taken of them so far this year
• 79% believe they look better in person than in photographs (do you?)
  
• 26% chose weight as the feature they dislike the most in photos
• Men have an average of 73 photos taken of them, while women have only 38

Are there any other questions you wish Nikon had included in the survey? Let us know, and we’ll conduct “research” with PetaPixel polls!
