Playing with in-camera HDR
The Pentax K7 has a provision in its menus for creating high-dynamic-range photos on the fly, right in the camera.
HDR photography has been badly abused, as you can see in terrible examples all over the web. But used correctly it can make photographs of great depth and subtlety. The Pentax in-camera photos turn out surprisingly good; the only catch is, you really need to use a tripod, as the camera takes three separate exposures and combines them.
The result, as you can see here, is a shot that offers something like the full dynamic range of traditional black and white film. It’s a lovely look and one I’ll be playing with more, clearly. The newest Pentax in the line-up, the newly announced K5, apparently manages to merge the three files cleanly even if you don’t use a tripod, which would make things ever so much easier.
Backpacker’s lunch
Question: Why does this kind of food taste so good in the mountains?
All right, that’s rhetorical.
One cool thing about this trip was, I carried the K20D with the DA* 16-50 zoom around my neck just about every single hour of every single day. This was a bit of a leap of faith, given the sharp volcanic dust of the Oregon Cascades and the several days of rain I carried it in.
Good news: The camera survived.
Better news: I used it to take lots of photos, which wouldn’t have been taken with another camera — say a 5DII — that I had to be fussier about.

Pentax K-7: First impressions
If it’s not love at first sight, it’s close.
The K-7, which arrived last week, has been a clear winner for me, right from the first touch. It feels as good in the hand as, say, a Nikon F100 without being big and heavy.
I’ve been using it every day, especially as I begin to explore the idea of digital black and white photography.
Here’s how it looks so far:
- Autofocus — always Pentax’s weak spot — is much improved over anything previous. I won’t be covering track and field, or shooting birds in flight, but I also won’t be cursing a camera (K20D anyone?) that simply can’t latch on to a face at a social gathering.
- The feel: As I said above, it feels great in the hand — tight, compact and well machined. It sounds good, too, quieter and more refined than the K20D, which tended to thunk.
- Metering seems more accurate than the K20D, which often needed about +2/3 stop of compensation. Not a big deal, though.
- The control layout is just enough different from the K20D to be irritating. It’s better, I think. But my hands don’t know where the buttons are anymore.
- Big negative: The SD card slot is terribly awkward when it comes time to remove the card. People with big hands are going to be tempted by forceps.
- Low light/high ISO: As everyone says, not as clean as you might like above 800. But this is a complicated issue, and I’m not sure it’s a problem that can’t be easily fixed in post. Rumor has it that Lightroom 3, now in beta, does wonders. That would be great; I’ll wait for the actual release. A head to head comparison with the K20D at 1000, shooting with the Pentax 21 Ltd on both cameras, produced much sharper, if slightly noisier, images on the K-7. This could be a clue that in-camera sharpening is more intense on the new body.
More as I figure things out. The manual is the size of a novel and seems to be written in postmodernist Swahili.

Flash-blur in medium format
Here’s a quick flash-blur shot in the woods taken on the Pentax 645. It’s not stunning, but I really like the way the vines creeping up the front of the tree to the right were outlined in shadow. That’s an effect I keep working to replicate, not always successfully.
Again, one to be colored and reposted.
The poor man’s 85mm f/1.4 lens…
… Better known as the humble SMC-M 50mm f/1.4, on an APS-C crop body like the Pentax K20D.
More playing around with the idea of digital black and white. It’s too smooth for a Tri-X fan like me, but it has its own buttery charm.
I’ll be interested to see what these photos look like with the MIS Eboni inks (when they arrive) on the Epson C88.
