How to take photos…..IN SPACE!!!

“We always sent cameras outside with the guys during the EVAs (Extra-Vehicular Activity – NASA speak for space-walk). They were mostly stock D2Xs, but had some minor mods in order to deal with the rigors of functioning in a vacuum with several hundred degree thermal swings. They had a custom fit thermal blanket wrapped around them, a large viewfinder so that they can be used with the helmet, and a big button that could be pushed with those oven-mitt gloves to release the shutter. We turned them on before they went into the airlock and used Program mode, then hoped for the best.” -Captain Alan Poindexter, Photography In Space

I usually steer far clear of gear and technique blogs, but this post on Luminous Landscape is worth a quick look. Taking pictures in space is no easy task, but with Captain Alan Poindexter’s help, you might return with a few keepers. Poindexter, astronaut and former commander of Space Shuttle Discovery, was picked to be lead Photo/TV crewmember on STS-122 in 2008, and shared a few of his experiences dealing with the difficulties of photographing in space. When taking pictures from space, you’ve got a lot to deal with. Light is very low, everything is in constant motion, and there’s a host of engines and fans causing most surfaces in the shuttle to vibrate. One of the images presented is a 4-second exposure of the coast of India against stars in space; during that exposure, the shuttle traveled 20 miles. And contemporary digital sensors allow the photographer to use light reflected off the Earth as a light source. Some scenes had 16 or 17 stops of dynamic range; and with the fast speed of the orbit, lighting conditions change quickly. Good luck on your next trip outside the Earth’s atmosphere!

While you’re at it, why not look through Hasselblad’s photography manual for NASA astronauts, or large collections of photography from the early Mercury and Gemini missions.

Reddit users discuss the most powerful images they’ve ever seen (NSFW)

I’m always fascinated to learn how people outside of the insular photo community interact with and relate to photography, especially photojournalism. This Reddit thread, posted to the AskReddit subsection of the site, offers just such a glimpse into how (a section of) the public reacts to imagery, focusing on “powerful” photos. The gallery presented above collects the 10 most popular images in the thread and the most popular opinion posted in reply to those images. I’ve added caption and photographer information where I could find it.

The initial poster posed the question “Reddit, what is the most powerful photo you have ever seen?” and, to start off the discussion, offered this image of a monk praying for a dead man in a Chinese train station. This Reddit thread is particularly notable because of its popularity: the thread was featured on the front page of Reddit (no small feat for a site that receives thousands and thousands of posts each day), was posted to one of the most popular subsections (with 1.2 million subscribers), and, as of my writing, the thread had a total score upwards of 1200 and nearly 4000 comments. It’s a very popular post, to say the least.

The demographics of Reddit are hard to know, but a few attempts have been made. The site’s users are about 80% male, are 80% American, are middle class, have some college education, and are under 35 (most under 25). That doesn’t mean the respondents in the thread fit into this demographic, but it’s a good approximation.

So, taking a few assumptions, the thread shows us the types of pictures that young, educated, American men find important, powerful, and interesting. This is a demographic for which much of our culture is targeted and which I’m sure many magazines and newspapers would love to appeal to.

This selection is striking to me for a few reasons. One, it’s a pretty interesting collection of images from a community whose stock and trade is usually closer to LOLcats and “fail” pictures (~1.5 million subscribers) than great visual journalism (~400 subscribers). Two, it includes some very subtle pictures, especially those by NASA and those focusing on political tensions. The image of the sunset on Mars, in particular, is a wonderful surprise and a sensitive choice. It’s certainly not an “obvious” picture; the image speaks deeply about humanity’s role in the universe, but in a less clear way than, perhaps, The Blue Marble. Three, there are no images from Iraq or Afghanistan (the boy receiving the flag from his father’s casket comes close) and few from the US. The selection reflects some very contemporary events, but few are directly related the community’s own experience. Four, at least half of the images aren’t the sort that win awards, though a few here are from the canon of photojournalism (including the colorized self-immolation picture). In spite of that, the images communicate quite powerfully. Content is king.

Most of all, this selection gives me hope that strong imagery still has the power to reach out to the public, even sections of the public which may have been written off by publications desperate to hang on to their aging and dwindling audiences. Quiet and emotive imagery still resonates with the young and digital audience raised on the never-not-breaking-news cycle.
