In Chicago, the police are asking loyal citizens to report anyone seen using a map or binoculars, or taking photographs.

Meanwhile in California, police are stopping drivers who have done nothing wrong in order to compliment their driving and give them $5 gift vouchers.

Both of these seem to me to be misguided. The former is obviously nutty; do they really want the 911 dispatchers bothered by some paranoid who just saw someone take a picture of Chicago’s art deco architecture?

The latter I can understand the motivation behind, but I can’t help wondering how many recipients will feel that the gift voucher is worth  the stress and/or anger of being pulled over. And for a US cop, any time you stop a vehicle, you’re risking your life; I can imagine them stopping a good driver who happens to have a car full of drugs, and having him freak out and start shooting.

According to IRNA, the official Islamic Republic news agency, the national Police chief has implicitly verified the news about the confiscation of a number of squirrels, equipped with eavesdropping devices, on the Iranian borders. He has declined to give any more details, but, reportedly, when asked about the confiscation of 14 spy squirrels, he stated, “I have heard about it, but I do not have precise information”. IRNA adds, “These squirrels were equipped by foreign intelligence services, but were captured two weeks ago by the Police”.

Life imitates Flickr?

As you may have gathered if you subscribe to my Flickr stream, the infamous Nikon scanner decided it didn’t want to scan any more. Or rather, it would scan, but the scan head wouldn’t move, resulting in some interesting modern art.

I took the case off and looked for any obviously fixable mechanical problems, but couldn’t see any. It would probably be possible to get it working by disassembling the mechanism, but I’m not that mechanically oriented.

It’s not like I’ve abused the scanner, and it has only had light residential use. So that’s definitely the last Nikon product I will ever buy.

I zipped off to the web and did a quick search for reviews of film scanners. Turns out that technology has advanced (as usual). Canon now have dual-mode flatbed/film scanners that are so good that they have stopped making old-style dedicated film scanners. Their finest model is also less than half the price the Nikon was back when it was new.

So, I bought a Canon CanoScan 9950F from Newegg. It arrived yesterday. It’s clearly a pro grade scanner; it feels far more hefty and resilient than any other flatbed I’ve used. It also has two killer features.

The first is that you can load it with up to 30 images (5 strips of negatives) in one go, and it’ll churn away for an hour or so and scan them all automatically. Major time saver.

The second is that it has an adaptor for larger film sizes, including 120 and 645. So I’ll be able to scan my dad’s prize winning 645 photos. It’s also higher resolution than the Nikon, with better bit depth.

It also does all the usual flatbed stuff, including turning documents into PDF with OCR. I use this to turn interesting magazine articles into PDFs for reference.

So, how do the results look? At least as good as the Nikon, and the software is miles better. The FARE auto-fix stuff even seems to do a better job than VueScan, though the sharpening is a bit over-zealous (but can be turned off).

The most popular SLR on Flickr is the Canon Digital Rebel XT.

The most popular point-and-shoot is the Canon PowerShot SD400.

Guess which two cameras I use?

It’s a bit of a surprise to me, because I generally don’t hold with the theory that the best product wins. However, perhaps it’s the case that the product that’s most popular with the kind of enthusiasts that post to Flickr, is the best.

In a few years, cameras will all have single chip GPS units in them. They’ll tag their photos with the location where you took them as a matter of course, like they already tag the time and date.

Some of us are unwilling to wait a few years. I’m sure you, like me, have sat down with a map and a stack of holiday photos and thought “OK, where on earth was that building?”. My current project of scanning and annotating hundreds of old family photos would be so much easier if I could have some clue as to at least the location and the year.

Which is probably why Sony have just launched a rather neat keychain GPS. No display, not many controls, you just clip it to your bag and forget about it. At the end of the day you connect it to the computer, run some software, and your photos are annotated with location information.

However, you don’t need a special Sony GPS for that. There’s a handy Mac application called GPSPhotoLinker that will download the automatic track data from a Garmin or Magellan GPS, cross-reference it with the timestamps on a bunch of photos, and re-write their EXIF information to add longitude, latitude, city, state and country.

We tried it out in Austin on Wednesday. It seems to work quite well, so we’ll take the GPS with us when we go to Germany.

As well as embedded EXIF tags, known as geocoding, there’s also the cruder hack of geotagging, where you add the latitude and longitude as Flickr tags. While this avoids the problem of dumb software stripping EXIF information, it messes up your Flickr tags page and relies on Flickr, so I’m not keen on it. I want my metadata in the file with the image, where it belongs.

OK, I think I now realize why I’m the only one surprised that digital photography has changed things so much.

Dan wrote:

In my experience, most people can’t count on getting more than 2-3 usable prints out of a roll of 27 shots.

Wow. If I only got 2-3 usable shots out of a roll, I’d have given up photography a long time ago.

Let’s consider our recent Extreme Squirrel Feeding outing. 21 shots. 6 were duplicates, i.e. basically the same shot as another one, and I picked the best. 8 were worth uploading. So that’s about a 50% hit rate.

For the Vegas 2003 photos, if I eliminate panorama pieces there were 91 shots initially. 7 duplicates leaves 84, and I uploaded 38. So again, about 50%, as there are a few that are perfectly good photos but just weren’t relevant to the narrative so didn’t get uploaded.

If I go back to film, the hit rate is higher, as I was more careful not to waste shots. I’m trying to shoot more with digital, but old habits are hard to break.

Partly, I think it’s that I put quite a bit of thought and planning into photos. I’ll often walk around and look at something from different angles and different positions, evaluating the light and so on, before picking the place I want to take the shot from. At that point there’s not much need for multiple exposures. Other people seem to take pictures from wherever they happen to be standing when they get the idea, and then they’ll move and realize there’s a better angle and take another photo, and another, and so on.

I don’t know which approach is better. Taking lots of shots might result in unexpected great images, and might be better for learning. On the other hand, you don’t always have the luxury of multiple takes, so sometimes you need to get ready and be in the right place ready for the photo. Plus, of course, there’s still a cost even to digital photos–time taken downloading, examining, and so on. I quickly learned that you can’t judge whether a photo is any good based on how it looks on the camera’s LCD. At best, you can eliminate a few that are so bad that the defects are visible even on the LCD.

Now that I’ve been participating in Flickr for a while, I’ve realized that digital technology has fundamentally changed the nature of photography. Perhaps I wasn’t looking in the right places, but I don’t recall seeing any discussion of this amidst the hype about Things Digital.

On the face of it, digital cameras shouldn’t have been that big of a disruptive factor. Film cameras were so cheap they were given away as promotional items, whereas digital cameras were hundreds of dollars. (Still are, if you want a decent one.) Minilabs had brought 1 hour processing to the world, and dropped costs to around 30¢ a picture. It’s not like there was anyone who needed to think about the expense involved in taking a particular shot.

Of course, there’s an immediacy to digital; you can print your photos in a minute or two, and you can print a single photo without waiting until you finish a roll. Yet film got there first, in the shape of Polaroid, and look what happened to them. Also, printing your own digital photos is expensive—you end up eating up any cost savings you made by shifting from film. Also, if you’re lazy or forgetful like me, you let images collect on your memory card and download them once a week.

Is it the Internet that has been the catalyst of change? Again, I’m not really convinced. People had flatbed scanners long before they had digital cameras, and plenty of people still dislike viewing photographs online, in spite of the superior image possible from a computer screen.

So it seems as though digital photography doesn’t really offer anything all that radical; just a combination of minor improvements. Yet somehow, digital photography has led to radical changes.

First off, it has changed the nature of the subjects people take photographs of. As a child, I was lucky enough to be given a camera and plenty of film. I started off taking pictures of objects that I found interesting—close up pictures of toys, the grass under my feet, and so on. It didn’t last, though. I don’t remember whether it was explicitly communicated to me, but I quickly learned that the primary purpose of photography was to record pictures of people grinning while standing in front of famous places.

Now, though, everyone seems to be reconnecting with the childish glee of being able to record any small piece of the world they see, and show it to other people. With a digital camera, people somehow feel free to photograph a discarded beer can, a rusting sign or the bruise on someone’s leg.

The second big change is commentary. Partly it’s the fact that you can access the photos immediately, but I think a lot of it is that you have a natural way to associate comments with the picture, without having to start a scrapbook. (Not that there’s anything wrong with that…)

My mother used to write on the back of prints with a pen. This was less than ideal. With a ball-point pen the smooth front surface would often get visible markings, and the ink would generally rub off all too easily.

With digital photos online, the commentary can be more of a shared, social, collaborative experience. And you don’t need to turn the photo over to see the words.

The third change is that photography has been democratized. Yes, professionals can often do a better job, turning out photos of consistently high quality; but it seems as though with persistence and lots of experimentation, all kinds of ordinary untrained folk are capturing occasionally stunning images. Maybe they don’t know how, but that can come later.

The final change is the sheer mass of images available to everyone to look at. This is really a side effect of big change #1, that people take pictures of everything now, combined with the existence of handy Internet web sites. Want to see a picture of (say) a steam train, a glass of water, a capybara, or a sock? There are hundreds on Flickr, and if you run out there you can try any of half a dozen other photo sites, or Google image search.

I just discovered something interesting. Under US law, buildings constructed after 1990 are copyrighted. That means our house is subject to copyright, and as legal owner I can demand licensing fees from anyone who wants to take pictures of the street that happen to include our house.

The more corporate interests force ever-stronger copyright laws on us, the more I find myself questioning copyright. For example, the RIAA lawsuits against MP3 downloaders have made me wonder: why should artists continue to get money every time someone plays a recording of their music? I don’t get extra money every time someone looks at a web site I created; the very idea is laughable. Yet web sites are copyrighted too.

[Update: Looking for a more positive story about ubiquitous cameras?]

David Brin wrote about the coming social revolution at length in his book The Transparent Society. Momus provided some handy tips in his song The Age of Information. Now Dog-Shit-Girl has demonstrated the dangers of not picking up the courtesy cluephone.

We live in a world where increasing numbers of people have digital cameras. In fact, in a few years the majority of people will have a mobile phone with built-in camera and Internet connection. This means that if you are going to be an antisocial ass in public, there’s a good chance that you will be recorded, your antics will be publicized, and you will be mocked. The worse your behavior, the more widespread your infamy. If what you do is bad enough, you might get threats; you might find that people recognize you, point at you in the street and yell at you.

You can whine all you like about privacy and rights; it won’t do any good. The Internet and digital cameras are not going to go away. Legislation won’t stop it, the transparent society is coming. My advice is to learn to live in it. People will be able to publish facts about you to a massive audience, so it’s probably a good idea to make sure the facts on offer are favorable ones.

In a way, it’s a return to the past. When we lived in villages where everyone knew everyone else, the antisocial would become outcasts. Now we’re headed back that way; the only difference is the size of the village.

Since I know people find my web pages while searching for information about Nikon scanners and Mac OS X, I’d like to offer the following endorsement:

The Ratoc FR1SX Ultra-SCSI to Firewire adaptor works perfectly with Mac OS X 10.3, and doesn’t need any drivers.

Plug the unit in to the back of your SCSI-based Nikon film scanner, and you suddenly have a Firewire-based Nikon film scanner. This can then be used with Ed Hamrick’s excellent VueScan software to fulfil all your scanning needs.

No adaptor drivers, no Nikon drivers, no Nikon software of any kind—so this solution should work fine with 10.4 / Tiger and other forthcoming OS X versions too.

Unlike USB options, the Firewire interface seems to result in scanning being just as fast and reliable as it was with SCSI.
