Making useful photographs

May 19, 2021 in Aviation, Photography | Permalink

What does it mean when perhaps hundreds of thousands of one’s photos appear in articles, essays and posts all over the Web?

It means they’re useful. That’s why I posted the originals in the first place, and licensed them to require only attribution. Because of that, I can at least guess at how many have been put to use.

For one example subject, take Lithium, a metal in the periodic table. Lithium is making news these days, because it’s both scarce and required for the batteries of electric and hybrid vehicles. At issue especially is how and where lithium is extracted from the Earth. As Ivan Penn and Eric Lipton put it in The Lithium Gold Rush: Inside the Race to Power Electric Vehicles (6 May in The New York Times), extraction “might not be very green.”

But it is blue. Or turquoise. Or aqua. Or whatever colors you see in the photo above.

I took that shot on a 2010 flight over Nevada. Looking out the window, it’s hard to miss lakes of bright colors on the desert floor, looking like stained glass windows into the Earth. I didn’t know at the time that the puddles were lithium, but I did know they’d be useful when I published them, along with whatever information a little bit of research would reveal about them. After I did the research, I put 17 photos in an album on Flickr titled Lithium Mines in Nevada and added the same set to another album called Mines and Mining, which is now 329 photos long.

Also on that flight, which produced 130 photos now in an album called 2010_08_06 rno-phx-bos, other topics of interest are the Shoshone Mountains, Yucca Lake and Yucca Flat (with “subsidence craters” over underground nuclear bomb explosions), the Nevada Test Site, (where hundreds of atomic bomb tests took place, among other interesting things, “Doom Town” on Frenchman Lake, Broom Lake in Area 51, Creech Air Force Base (from which military drones are remotely controlled), Grand Canyon, and Buffalo at night. None of the photos of mine at those links (all in Wikipedia) are especially artistic. In fact most of them make me cringe today, because I hadn’t yet mastered Photoshop when I posted them in the first place. Back then I shot only .jpgs, rather than RAW photos, which means I can’t go back do much to improve them. But all are useful, especially to writers and publications covering the topic of lithium mining. For example, my photos of those lithium lakes appear in—

And those are just the first six among 23,200 results in a search for my name + lithium. And those results are just from pubs that have bothered to obey my Creative Commons license, which only requires attribution. Countless others don’t.

Google also finds 57,400 results for my name + mining. On top of those, there are also thousands of other results for potash, river, geology, mining, mountains, dunes, desert, beach, ocean, hebrides, glacier, and other landforms sometimes best viewed from above. And that’s on top of more than 1500 photos of mine parked in Wikimedia Commons, of which many (perhaps most) are already in Wikipedia (sometimes in multiple places) or on their way there.

And those are just a few of the many subjects I’ve shot, posted and annotated to make them useful to the world. Which is why I’m guessing the number of photos actually being used is in the hundreds of thousands by now.

I have placed none of those photos in any of those places. I just put them up where they can easily be found and put to use. For example, when I shot Thedford, Nebraska, I knew somebody would find the photo and put it in Wikipedia.

Shots like these are a small percentage of all the photos I’ve taken over many decades. In fact, most of my photography is of people and scenes, not stuff like you find in the links above.

But apparently my main calling as a photographer is to push useful photos to the edge of the public domain, and to describe and tag them in ways that make them easy for researchers and journalists to find and use. And so far that has been a very successful strategy.

Addendum:::

So I have a camera question for the fellow photographers out there.

My main camera is a 2012-vintage Canon 5D Mark III , which replaced a 2005-vintage Canon 5D (source of the lithium lake shots), which replaced a Canon 30D of the same generation, and a Nikon Coolpix before that. All of these are retired or beat up now. Being um, resource constrained, every camera and lens I’ve used in this millennium I’ve either rented or bought used.

Now, out of great kindness, an old friend is giving me a Sony a7R that has been idle since she replaced it with a Sony a7Riii. I’ve played with her newer Sony, and really like how much lighter mirrorless full-frames can be. (And the a7R is lighter than the a7Riii.) The question now is what kind of lens I want to start with here, given that my budget is $0 (though I will spend more than that). The Sony equivalent of the lens I use most, a Canon 24-105 f4 L, runs >$1000, even used.

I suppose I could get non-Sony lenses for less, but … I’m not sure that’s the way to go. I’m kinda tempted to get a telephoto zoom or prime for the Sony and keep using the Canon for everything else. But then I’m carrying two cameras everywhere.

But I just looked at Ken Rockwell’s take on the Sony 24-105mm f/4
FE G OSS Full-Frame E-Mount, which appears to outperform the Canon equivalent (two links back) so maybe I’ll find a bullet to bite, and spend the grand.

[25 May…] And I did that. The lens just arrived. Now I just need to match it up with a7R, which will probably happen next Tuesday. I trust you’ll see some results soon after that.

[12 April 2023…] That lens has proven amazing. It is about as sharp as a lens can get, which is unusual for a zoom. It is very sturdy: much more so than the Canon equivalent on which I long depended. Last year I added the Sony 70-200mm f/2.8 GM OSS II, which Ken Rockwell reviews here. It is beyond outstanding. To go with both lenses I bought a new Sony a7iv, and started shooting with one of these two lenses on the new camera and the old a7r. This is a great way to shoot weddings and events, since one is ready to shoot pretty much anything. But alas, the a7r blew out its shutter at the first wedding I shot. Fixing it costs more than the same camera on the used market, and replacing it is also out of my price range. So I have to switch the two lenses on one camera. I can live with that.

Where did “Chinese Wall” come from?

September 16, 2010 in Books, Quote | 7 comments

The meaning of the term “Chinese wall” is clear. It’s a virtual partition meant to keep potentially conflicted interests apart: a private partition meant to keep interests apart, even if what’s happening on both sides is obvious to the other.

What’s not clear, at least to me, is where the term came from. Wikipedia’s Chinese wall article doesn’t say that. I recall “Chinese wall” meaning a thin one: You can hear what’s happening on the other side, but can pretend not to notice. Still, not good enough. So I’m hoping one of you can point me to a source I can cite in the book I’m writing.

And if you’re wondering why I’m posting less these days, it’s because my nose is on the book’s grindstone.

What’s right with Wikipedia?

November 30, 2009 in Blogging, infrastructure, Journalism, News, problems, radio | 11 comments

“I make my living off the Evening News
Just give me something: something I can use
People love it when you lose
They love dirty laundry.
— Don Henley, “Dirty Laundry”

Look up “Wikipedia loses” (with the quotes) and you get 20,800 results. Look up “Wikipedia has lost” and you get 56,900. (Or at least that’s what I got this morning.) Most of those results tell a story, which is what news reports do. “What’s the story?” may be the most common question asked of reporters by their managing editors. As humans, we are interested in stories — even if they’re contrived, which is what we have with all “reality” television shows.

Lately Wikipedia itself is the subject of a story about losing editors. The coverage snowball apparently started rolling with Volunteers Log Off as Wikipedia Ages, by Julia Angwin and Geoffrey A. Fowler in The Wall Street Journal. It begins,

Wikipedia.org is the fifth-most-popular Web site in the world, with roughly 325 million monthly visitors. But unprecedented numbers of the millions of online volunteers who write, edit and police it are quitting.

That could have significant implications for the brand of democratization that Wikipedia helped to unleash over the Internet — the empowerment of the amateur.

Volunteers have been departing the project that bills itself as “the free encyclopedia that anyone can edit” faster than new ones have been joining, and the net losses have accelerated over the past year. In the first three months of 2009, the English-language Wikipedia …

That’s all you get without paying. Still, it’s enough.

Three elements make stories interesting: 1) a protagonist we know, or is at least interesting; 2) a struggle of some kind; and 3) movement (or possible movement) toward a resolution. Struggle is at the heart of a story. There has to be a problem (what to do with Afghanistan), a conflict (a game between good teams, going to the final seconds), a mystery (wtf was Tiger Woods’ accident all about?), a wealth of complications (Brad and Angelina), a crazy success (the iPhone), failings of the mighty (Nixon and Watergate). The Journal‘s Wikipedia story is of the Mighty Falling variety.

The Journal’s source is Wikipedia: A Quantitative Analysis, a doctoral thesis by José Phillipe Ortega of Universidad Rey San Carlos in Madrid. (The graphic at the top of this post is one among many from the study.) In Wikipedia’s Volunteer Story, Erik Moeller and Erik Zachte of the Wikimedia Foundation write,

First, it’s important to note that Dr. Ortega’s study of editing patterns defines as an editor anyone who has made a single edit, however experimental. This results in a total count of three million editors across all languages.  In our own analytics, we choose to define editors as people who have made at least 5 edits. By our narrower definition, just under a million people can be counted as editors across all languages combined.  Both numbers include both active and inactive editors.  It’s not yet clear how the patterns observed in Dr. Ortega’s analysis could change if focused only on editors who have moved past initial experimentation.

Even more importantly, the findings reported by the Wall Street Journal are not a measure of the number of people participating in a given month. Rather, they come from the part of Dr. Ortega’s research that attempts to measure when individual Wikipedia volunteers start editing, and when they stop. Because it’s impossible to make a determination that a person has left and will never edit again, there are methodological challenges with determining the long term trend of joining and leaving: Dr. Ortega qualifies as the editor’s “log-off date” the last time they contributed. This is a snapshot in time and doesn’t predict whether the same person will make an edit in the future, nor does it reflect the actual number of active editors in that month.

Dr. Ortega supplements this research with data about the actual participation (number of changes, number of editors) in the different language editions of our projects. His findings regarding actual participation are generally consistent with our own, as well as those of other researchers such as Xerox PARC’s Augmented Social Cognition research group.

What do those numbers show?  Studying the number of actual participants in a given month shows that Wikipedia participation as a whole has declined slightly from its peak 2.5 years ago, and has remained stable since then. (See WikiStats data for all Wikipedia languages combined.) On the English Wikipedia, the peak number of active editors (5 edits per month) was 54,510 in March 2007. After a more significant decline by about 25%, it has been stable over the last year at a level of approximately 40,000. (See WikiStats data for the English Wikipedia.) Many other Wikipedia language editions saw a rise in the number of editors in the same time period. As a result the overall number of editors on all projects combined has been stable at a high level over recent years. We’re continuing to work with Dr. Ortega to specifically better understand the long-term trend in editor retention, and whether this trend may result in a decrease of the number of editors in the future.

They add details that amount to not much of a story, if you consider all the factors involved, including the maturity of Wikipedia itself.

As it happens I’m an editor of Wikipedia, at least by the organization’s own definitions. I’ve made fourteen contributions, starting with one in April 2006, and ending, for the moment, with one I made this morning. Most involve a subject I know something about: radio. In particular, radio stations, and rules around broadcast engineering. The one this morning involved edits to the WQXR-FM entry. The edits took a lot longer than I intended — about an hour, total — and were less extensive than I would have made, had I given the job more time and had I been more adept at editing references and citations. (It’s pretty freaking complicated.) The preview method of copy editing is also time consuming as well as endlessly iterative. It was sobering to see how many times I needed to go back and forth between edits and previews before I felt comfortable that I had contributed accurate and well-written copy.

In fact, as I look back over my fourteen editing efforts, I can see that most of them were to some degree experimental. I wanted to see if I had what it took to be a dedicated Wikipedia editor, because I regard that as a High Calling. The answer so far is a qualified no. I’ll continue to help where I can. But on the whole my time is better spent doing other things, some of which also have leverage with Wikipedia, but not of the sort that Dr. Ortega measured in his study.

For example, photography.

As of today you can find 113 photos on Wikimedia Commons that I shot. Most of these have also found use in Wikipedia. (Click “Check Usage” at the top of any shot to see how it’s been used, and where.) I didn’t put any of these shots in Wikimedia Commons, nor have I put any of them in Wikipedia. Other people did all of that. To the limited degree I can bother to tell, I don’t know anybody who has done any of that work. All I do is upload shots to my Flickr site, caption and tag them as completely as time allows, and let nature take its course. I have confidence that at least some of the shots I take will be useful. And the labor involved on my part is low.

I also spent about half an hour looking through Dr. Ortega’s study. My take-away is that Wikipedia has reached a kind of maturity, and that the fall-off in participation is no big deal. This is not to say that Wikipedia doesn’t have problems. It has plenty. But I see most of those as features rather than as bugs, even if they sometimes manifest, at least superficially, as the latter. That’s not much of a story, but it’s a hell of an accomplishment.

Toward Celebrating 8-11 Day

August 8, 2009 in Ideas, infrastructure, Politics, problems | 5 comments

2close2nstar

Mark Finnern has a great idea: Wikipedia papers. Specifically,

Every student that takes a class has to create or improve a Wikipedia page to the topic of the class. It shouldn’t be the only deliverable, but an important one.

The Wikimedia organization could help the professors with tools, that highlight the changes that a certain user has done on a page. You only pass, when the professor is satisfied with the scientific validity of the page. One could even mark the pages that went through this vetting process differently.

Instead of creating papers that end up in a drawer, you would create pages that you even feel ownership of and would make sure that they stay current and don’t get vandalized. You could even link to them on you LinkedIn profile.

It would make an enormous difference to the quality of Wikipedia year over year. One can think of wiki-how and other pages that could be improved using the same model.

There are other reasons. For example, Wikipedia has holes. Not all of these line up with classes being taught, but some might. Let’s take one example…

811

Wikipedia has an entry for 5-1-1, the phone number one calls in some U.S. states for road conditions. It also has an entry for 9-1-1, the number one calls in North America for emergency services. And, while it has an entry for 8-1-1, the “call before you dig” number in the U.S., it’s kinda stale. One paragraph:

All 811 services in the U.S. will end up using 611 by early 2007, as the United States Federal Communications Commission (FCC) in March 2005 made 811 the universal number for the 71 regional services that coordinate location services for underground public utilities in the U.S.[1][dated info] Currently, each of these “call before you dig” services, has its own 800 number, and the FCC and others want to make it as easy as possible for everyone planning an excavation to call first. This safety measure not only prevents damage that interrupts telecommunications, but also the cutting of electricity, water mains, and natural gas pipes. Establishment of an abbreviated dialing number for this purpose was required by the Pipeline Safety Improvement Act of 2002.

That last link takes you to one of those “Wikipedia does not have an article with this exact name” places. The “call before you dig” link redirects to Utility location. There you’ll find this paragraph:

One-call, Miss Utility, or Underground Service Alert are services that allow construction workers to contact utility companies, who will then denote where underground utilities are located via color-coding those locations. As required by law and assigned by the FCC, the 8-1-1 telephone number will soon be used for this purpose across the United States.

Well, it’s already being used. And it’s way freaking complicated, because there’s this very uneven overlap of entities — federal government, state goverenments, regional associations, and commercial entities, to name a few — that all have something to say.

For example, the U.S. Department of Transportation Pipeline and Hazardous Materials Safety Administration, or PHMSA. Right on their front page, they tell you April is Safe Digging Month. Good to know. April of what year? Next to a blurred emblem with an 811 over a shovel (a poor version the above, which comes from the Utility Notification Center of Colorado) and a horribly blurred graphic proclaiming WE SUPPORT SAFE DIGGING MONTH, a Call Before You Dig link leads to a page that explains,

Guidance for implementing safe and effective damage prevention for underground utilities was established by the Common Ground Alliance (CGA), a national organization representing all underground utility stakeholders. Calling before you dig is the first rule to remember when conducting underground related activities, no matter what the job is. The law requires you to phone the “One-Call” center at 8-1-1 at least two days prior to conducting any form of digging activity.

No link to the Common Ground Alliance. That org (a domain squatter has its .org URL, so it’s a .com) explains that it’s “a member-driven association dedicated to ensuring public safety, environmental protection, and the integrity of services by promoting effective damage prevention practices.” Its news page mentions that, among other things, August 11 is “8-11 Day”. It has a press release template in Word format. It also has news that “MGH Hired as CGA 811 Awareness Contractor” in .pdf. Within that one finds MGH’s website URL, where one finds that the agency is @mghus, which may be the hippest thing in this whole mess.

Digging farther, one finds that there is an call811.com, which appears to be another face of the Common Ground Alliance. (If you’re interested, here are its “sponsors and ambassadors”.)

Also involved is the American Public Works Association. Apparently the APWA is the outfit behind what LAonecall (one of the zillion of these with similar names) calls “the ULCC Uniform Color Code using the ANSI standard Z53.1 Safety Colors”. APWA must have published it at one point, but you won’t find it on its website. Hey, Google doesn’t. Though it does find lots of other sites that have it. Most are local or regional governmental entities. Or utilities like, say, Panhandle Energy. Here’s the graphic:

colorcode

Here in New England (all of it other than Connecticut, anyway), the public face of this is Dig Safe System, Inc., which appears to be a nonprofit association, but there’s nothing on the site that says wtf it is — though it is informative in other respects. It does say, on its index page,

What is Dig Safe ®?

State laws require anyone who digs to notify utility companies before starting, and for good reason. Digging can be dangerous and costly without knowing where underground facilities are located.

Dig Safe ystem, Inc. is a communication network, assisting excavators, contractors and property owners in complying with state law by notifying the appropriate utilities before digging. Dig Safe®, a free service, notifies member companies of proposed excavation projects. In turn, these member utilities respond to the work area and identify the location of underground facilities. Callers are given a permit number as confirmation.

Member utilities, or contracted private locators, use paint, stakes or flags to identify the location of buried facilities. Color coding is used to identify the type of underground facilities… (and the same color coding as above)

I found out all of this — and much more — while I was researching for my column in the November issue of Linux Journal, which has Infrastructure the issue’s theme. I’m leveraging my leftovers here, closing one tab after another in my browser.

I’m also interested in approximately everything, one of which is the official-looking public graffiti on the ground all over the place. These are known locally as “dig safe markings”. At least that piece of the scattered one-call/call-before-you-dig/8-1-1 branding effort has taken root, at least here.

Anyway, I’d love to see a Wikipedia entry or two that pulls all this together. Maybe I should write it, but I’m busy. Hey, I’ve done this much already. Some actual experts ought to pick up the ball and post with it.

Which brings us back to Mark’s suggestion in the first place. Have a class do it.

Hey, @mghus, since you’re in Baltimore, how about  suggesting a Wikipedia page project to The Civil & Environmental Engineering Department at UMBC?

Maybe for 8-11 Day?

WQXR goes to WNYC, WBCN leaves FM dial

July 15, 2009 in Business, Future, infrastructure, music, radio, Sports | 23 comments

Heard this morning on WNYC that the New York Times has unloaded its remaining broadcasting asset, which consists of the channel and facilities of WQXR, which has been a classical music landmark for as long as it’s been around. (One way or another, since 1929. Wikipedia tells the long story well.) The story on WNYC’s website says WQXR will become “part of” WNYC. I assume that means it will become non-commercial.

According to Bloomberg, the deal goes like this:

  • “Univision will pay Times Co. $33.5 million to swap broadcasting licenses and shift its WCAA broadcast to 96.3 FM from 105.9 FM, which will become WQXR… WCAA will get 96.3 FM’s stronger signal.”
  • “WNYC will pay Times Co. $11.5 million for 105.9 FM’s license and equipment and the WQXR call letters.”

WQXR was for a long time an AM/FM operation. The AM was on 1560, with a 50,000 watt signal out of a four-tower facility in Maspeth, Queens. The FM was for many years atop the Chanin Building, where it still maintains an auxilliary antenna. I have shots of the old and new antennas here and here. In 2007 the Times Co. unloaded its AM station, then (and still) called WQEW, to Walt Disney Co. for $40 million. It’s now Radio Disney, a kids’ station.

Since the 60s WQXR has shared a master antenna atop the Empire State Building with most of New York’s other FMs. This was their status in 1967. Wikipedia has a good rundown of what’s up there today. Scott Fybush also has a comprehensive report from 2003.

An open question is whether WQXR will remain a beacon on the dial. While other signals on the Empire State Building master antennas run 5000 to 6000 watts, the one on 105.9 is just 610 watts. According to WQXR’s  Web site, the station and has an audience of nearly 800,000 weekly listeners. How many of those will lose the signal? Coverage maps from radio-locator.com for 96.3 and 105.9 are here and here.

For the fully obsessed, here is a current rundown of everything on FM hanging off the Empire State Building, or within 1km of it.

Meanwhile, says here WBCN in Boston, a progressive rock radio landmark, is also getting yanked. You’ll still hear it on the Web, or if you are among the appoximately five owners of an “HD” radio receiver and close enough to WBCN’s transmiter on Boston’s Prudential Building in the Back Bay. Meanwhile Boston will get more of the usual: talk sports and “Hot AC” music. (To me “Hot AC” always sounded like an climate control oxymoron, while “adult contemporary” sounded like a euphemism for pornographic furniture.)
