Buying a Canon 5D Mark II, with lens? Buy it in Canada and save $250

I just got my new Canon 5D Mark II. (Let me know if you want to buy some of my old gear, see below...) This camera is creating a lot of attention because of several ground-breaking features. First, it's 22MP full-frame. Second, it shoots at up to 25,600 ISO -- 8 stops faster than the 100 ISO that was standard not so long ago, and is still the approximate speed of typical P&S today. It's grainy at that speed (though makes a perfectly good shot for web display) and it's really not very grainy at all at 3200 ISO.

Making videocalls work for the aged

While videoconferencing may not make sense for everyday use, I think it has special value for contact with distant relatives, particularly older ones who don't travel very much. They may not get to see the grandchildren, great-grandchildren or even children very often, and their lives are often marked by a particular loneliness, particular at senior homes.

But today's videoconferencing tools are getting quite good and will get even better. Skype now offers a 640x480 video call if you have enough bandwidth and CPU, which is not far off broadcast quality if not for the mpeg artifacts they have trying to save bandwidth. It's also pretty easy, as is Google's GMail video chat and several other tools. We're just a couple of years from HDTV level consumer video calling.

Many seniors, however are unfamiliar with or even afraid of many new technologies, and often in places where it's hard to get them. And this in turn means they can't readily set up computers, cameras or software. There is also still not internet access in many of the locations you might want ot reach, such as hospital deathbeds and senior homes. (Had they had the access in my stepfather's hospital room, I could have had a video conversation at the end; he died as I was heading to the plane.)

Video calls also offer extra human bandwidth, which is a big plus with people who are getting infirm, less strong of mind and hard of hearing. Reading lips can help improve how well you are understood, and physical cues can mean a lot.

And so I think it's crazy that senior homes, hospitals and hospices don't come standard with a video call station. This is not anything fancy. It's a computer, a webcam, and a megabit of internet. Ideally wireless to move into rooms for the truly infirm. Yet when I have asked for this I have found myself to be the first person to ask, or found that there are policies against internet use by any but the staff.

I'm going to describe two paths to getting this. The first uses off-the-shelf hardware and freeware, but does require that the staff of these facilities learn how to use the system and be able to set their residents up in front of it when it is time for a call. This is not particularly difficult, and no different then the staff being trained in any of the other things they do for residents and patients. Then I will discuss how you would design a product aimed for the sector, which could be used without staff help.

Disturbing abuse of the troops and those who care for them by AT&T and others

Today I was pointed to this advertisement asking you to buy prepaid phone cards for the troops.

AT&T has set up special phone stations near all major deployments in the Mid-East. Phone access for our troops is easy, but calls home remain expensive.

EFF Year in Review in Music

It's been a remarkably dramatic year at the EFF. We worked in a huge number of areas, acting on or participating in a lot of cases. The most famous is our ongoing battle over the warrantless wiretapping scandal, where we sued AT&T for helping the White House. As you probably know, we certainly got their attention, to the point that President Bush got the congress to pass a law granting immunity to the phone companies. We lost that battle, but our case still continues, as we're pushing to get that immunity declared unconstitutional.

PEW study on the future of the internet

PEW Research has released their recent study on the future of the internet and technology where they interviewed a wide range of technologists and futurists, including yours truly. It's fairly long, and the diverse opinions are perhaps too wide to be synthesized, but there is definitely some interesting stuff in there.

Not entirely fair review of the Gigapan imager

This is an unfair review of the "Gigapan" motorized panoramic mount. It's unfair because the unit I received did not work properly, and I returned it. But I learned enough to know I did not want it so I did not ask for an exchange. The other thing that's unfair is that this unit is still listed as a "beta" model by the vendor.

I've been wanting something like the Gigapan for a long time. It's got computerized servos, and thus is able to shoot a panorama, in particular a multi-row panorama, automatically. You specify the corners of the panorama and it moves the camera through all the needed shots, clicking the shutter, in this case with a manual servo that mounts over the shutter release and physically presses it.

I shoot a lot of panos, as readers know, and so I seek a motorized mount for these reasons:

  • I want to shoot panos faster. Press a button and have it do the work as quickly as possible
  • I want to shoot them more reliably. With manual shooting, I may miss a shot or overshoot the angle, ruining a whole pano
  • For multi-row, there's a lot of shooting and it can be tiresome.
  • With the right shutter release, there can be lower vibration. You can also raise the mirror just once for the whole pano, with no need to see through the viewfinder.
