Digital cameras, embrace your inner eBook

Lots of people are doing it -- using their digital camera as a quick way to copy documents, not just for taking home, but to carry around. Rather than carry around a large travel guidebook (where most of the weight is devoted to hotels and restaurants in other towns) we normally just photograph the relevant pages for the area we will be exploring. We also do it even with portable items like guides and travel maps since we don't really want the paper. We also find ourselves regularly photographing maps of cities, facilities and transit systems found on walls.

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.

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.

Panoramas of Stockholm, Sweden

I now have a gallery up of the panoramas from Stockholm, Sweden. While this was not the best time of year to be photographing that far north (except for the availability of fall colour) I generated a lot of panoramas of various sorts. The main reason was I am trying some new panorama software, known as AutoPano Pro. This software is one of the licencees of the interesting SIFT algorithm, which is able to take a giant pile of pictures, and figure out which ones overlap and setting up the blend.

4-segment tripod where bottom segment screws in

I have tripods with both 3 segments and 4 segments. A 4-segment tripod has 3 clamps per leg, which means 9 of them to open and close in extending and collapsing the tripod. That's a pain. Enough of one that you sometimes find yourself asking whether a shot is worth setting up the tripod. But even 3 segment tripods are only a bit better.

Professional lenses with built in sensors

A friend (Larry P.) suggested that the time was here for serious (ie. DSLR) cameras to undertake a design revolution. The old SLR design, with a mirror that flips up and must sit between the last lens element and the sensor, creates a lot of problems in designing the lens and camera systems. Yes, being able to view directly through the lens with your eye is a very useful thing. But at what cost?

Want a lossless jpeg editor

Photographers constantly debate about jpeg. Should they shoot in RAW or JPEG, for example. RAW preserves everything, but is much harder and bulkier to work with, so you will see serious pro photographers, who you think would always vote for the "never throw away" logic of RAW, tell you they work mostly in JPEG. I'm one of them. I use raw only for shots with high dynamic range, like night photography, and often shoot RAW+JPEG to work with the JPEGs and pull the RAWs if you need it.

Panoramas of Wyoming: Yellowstone, Tetons

Last weekend I had a great trip to Wyoming, staying in Jackson for a bit and then into Yellowstone with a Cody side-trip.

As always, tons of photos and a new gallery of panoramic photos of the area. My last trip to Yellowstone featured poor weather and a very early (low quality) digital camera so I was pleased to photograph it again.

Advice on what digital camera to buy

I do enough photography that people ask me for advice on cameras. Some time ago I wrote an article about what lenses should I buy for a Canon DSLR which has turned out to be fairly popular. The thrust of that article, by the way, is to convince you that there is only minimal point in buying a DSLR that can changes lenses and getting only one lens for it, even if you plan to get another lens later (after your camera has depreciated plenty without using its real abilities.)

Detecting bad photos in camera and after

As I've noted, with digital cameras we all take tons of photos, and the next task is to isolate out the winners. I've outlined better workflow for this and there are still more improvements we need in photo management software, but one task both cameras and photo management software could make easier is eliminating the plain bad shots.

Rotating digital picture frame

Digital Picture Frames are finally coming down to tolerable prices and decent resolutions. We are about to give my mother one that's 1024x768 and 15" on the diagonal. In part that's because I never got around to building one out of a laptop though I still think a linux distro that turned an old laptop into a digital PF would be a great idea because the ability to do wireless networking to subscribe to flickr and other feeds is the waiting killer app for these frames.

News: Burning Man burns on Monday

Update: I now have a whole Burning Man area on the blog!

I've not been blogging of late because I'm at Burning Man, and while normally I don't report breaking news in this blog, we just witnessed a strange event. Through accident or arson, the Man was set alight this evening shortly after totality began in the eclipse of the moon.
