Amazing 70-Year-Old Color Photos

Original image

Sometimes looking at old photographs makes me think of this exchange between comic-strip hero Calvin and his dad:

Calvin: Dad, how come old photographs are always black and white? Didn't they have color film back then?
Dad: Sure they did. In fact, those old photographs are in color. It's just the world was black and white then.
Calvin: Really?
Dad: Yep. The world didn't turn color until sometime in the 1930s, and it was pretty grainy color for a while, too.
Calvin: But then why are old PAINTINGS in color?! If the world was black and white, wouldn't artists have painted it that way?
Dad: Not necessarily. A lot of great artists were insane.

As absurd as it sounds, there is a kind of psychological truth to it -- having seen mostly black-and-white pictures of the world pre-1960 or so (I'm not counting Technicolor movies), I begin to imagine the past unfolding in monochrome. Every once in a while, though, a really old color photo made with some obscure, early color process will slip through and blow my mind.

But this really takes the cake: the Library of Congress has a Flickr page, on which they've posted thousands of color slides -- many of them hauntingly beautiful. The photographers worked for the Farm Security Administration and the Office of War Information, for whom many famous black-and-white pictures were taken around the same time (the iconic "Migrant Mother," for instance).

But rather than sending you off to pick through thousands of these photos on Flickr -- something of a laborious process -- we've compiled our favorites here. These are portraits almost as compelling as "Migrant Mother," but even more vivid -- almost hyper-real -- for their eye-popping color. (In fact, they hardly seem like historical photos at all.) 

As for the main image above: "This husky member of a construction crew building a new 33,000-volt electric power line into Fort Knox is performing an important war service, Ft. Knox, Ky. Thousands of soldiers are in training there, and the new line from a hydroelectric plant at Louisville is needed to supplement the existing power supply." 1940

AI Algorithm Tells You the Ingredients in Your Meal Based on a Picture

Your food photography habit could soon be good for more than just updating your Instagram. As Gizmodo reports, a new AI algorithm is trained to analyze food photos and match them with a list of ingredients and recipes.

The tool was developed by researchers at MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL). To build it, they compiled information from sites like All Recipes and Food.com into a database dubbed Recipe1M, according to their paper. With more than a million annotated recipes at its disposal, a neural network then sifted through each one, learning about which ingredients are associated with which types of images along the way.

The result is Pic2Recipe, an algorithm that can deduce key details about a food item just by looking at its picture. Show it a picture of a cookie, for example, and it will tell you it likely contains sugar, butter, eggs, and flour. It will also recommend recipes for something similar pulled from the Recipe1M database.

Pic2Recipe is still a work in progress. While it has had success with simple recipes, more complicated items—like smoothies or sushi rolls, for example—seem to confuse the system. Overall, it suggests recipes with an accuracy rate of about 65 percent.

Researchers see their creation being used as a recipe search engine or as a tool for situations where nutritional information is lacking. “If you know what ingredients went into a dish but not the amount, you can take a photo, enter the ingredients, and run the model to find a similar recipe with known quantities, and then use that information to approximate your own meal,” lead author Nick Hynes told MIT News.

Before taking the project any further, the team plans to present its work at the Computer Vision and Pattern Recognition Conference in Honolulu later this month.

UV Photos Show the Areas We Miss When Applying Sunscreen
Original image

Sunscreen only works if you're actually wearing it. And it's too easy to go through the motions of putting on sunscreen while still leaving large amounts of skin unprotected. Even if you're applying the recommended shot glass of sunscreen before you head out into the world, parts of your skin may still be exposed to harmful rays. Just check out these UV images taken by researchers at the University of Liverpool, spotted by the UK's Metro.

The black-and-white images were taken with a UV camera so that any part of the skin covered by UV-blocking sunscreen would appear dark. Skin without sunscreen on it, by contrast, remains visible. The 57 volunteers in the study—which was recently presented at the British Association of Dermatologists' Annual Conference—were instructed to apply sunscreen to their face as usual.

Some volunteers were more thorough than others, but as a whole, the group ended up missing a median of 9.5 percent of their faces. Men with beards tended to miss a lot of their faces, you might notice in the photos, and people seemed to have trouble with covering the full area around their mouth. However, the main problems occurred around the eyes. Many people missed their eyelids, and more than three-quarters of the group missed the medial canthal region, or the area between the bridge of the nose and the inner corner of the eye.

The finding is significant because the area around the eyes are particularly susceptible to skin cancer. According to the abstract presented at the conference, 5 to 10 percent of skin cancers occur on the eyelids.

Knowing this doesn't necessarily help, though. When the participants were brought back for a second visit, the researchers gave them new instructions that included data on cancer risks for eyelids, the results barely changed. People put slightly more sunscreen on around their eyelids (they missed a median 7.7 percent instead of 13.5 percent of the area) but almost everyone still missed their medial canthal area.

It's not a surprising finding, considering the fact that no one wants to get sunscreen in their eyes. Sunscreen manufacturers recommend that you keep it out of your eyes, and if it does run, you'll end up in tears. So it's not particularly useful to tell people they should be coating their eyelids in Coppertone.

To keep your face super smooth and reduce your likelihood of sun damage, then, the message is clear. Better get some shades, unless you've got a UV-blocking eyeshadow on hand. Better yet, get yourself a hat, too.
