Lenses as software

John Gruber links Brian Tiemann’s piece on the cost of platform switching.

The argument centers around that the cost of switching in photography is high because of lens investment just like the cost of switching in computers is high because of software (purchase) investment.

Bullshit.

Learning Programming Part 1: 5 million

“Five million, bitches”
—my new reply every time someone mentions Ruby

A friend of mine is learning to program, and how to learn a programming language came up.

There is a lot of people who are non-programmers or have taken programming classes and not yet learned to program. When I was a kid, those languages were BASIC, Logo, and Karel the Robot, now they are things like C#, Java, and Ruby. Still the same problem of “what programming language to start” rears its ugly head.

Bear Cans

I was amused to read about the bear Yellow Yellow’s ability to break into the BearVault 500.

When doing outdoor photography it is very important to know the bear-proof rules for your area. For instance, when I last hiked Tahoe, it was okay to use a bear-bag—a canvas bag that you throw up into the trees and anchor by tying to a tree. But in Yosemite and Mount Whitney, this is a big no-no as bears long ago figured out how to pull down a bear bag, you have to use a bear proof canister.

Luckily, all campsites at Yosemite have food lockers to protect your stuff.

Symmetrical compositions

After this article, Kara convinced me to sign up for the Worldwide Photo Walk this year. I ended up going to the Marin one even though there were five in SF.

The big challenge of an outdoor nature photo walk—besides watching others take better photos than you—is getting your gear down to something you can live with. Especially if you haven’t been photographing in forever. Even if you see something you like, it means compromises to get there. I noticed that the lighting was too flat, but the sky had nice texture, and from the town, I could see Rat Rock Island standing off the promontory.

I really had to shoot that:

Da Grip

I’m left-eyed.

Left-eyed
North Beach, San Francisco, California

Leica M8, Cosina-Voigtländer NOKTON 35mm F1.2 Aspherical
1/500sec, iso 320, 35mm (47mm)

No that’s not a Sharingan, just creative editing.

It’s not completely rare to see some left-eyed photographers, but that’s mostly because creative types tend to be left-handed.

I’m right-handed, but left-eyed.

This is the reason that I couldn’t get out of my athletic requirement by taking up riflery. I had to pull the trigger with my non-dominant hand which is a big disadvantage. And no, an eyepatch won’t correct this since I’m three diopters worse in the right eye. It flunks so badly that I barely pass a depth perception test even when corrected. I simply never look out of it.

All this is is a really indirect way of talking about some free schwag that Kara dropped off…

2009-06-25 Out comes the Leica

I haven’t shot the Leica in a long, long while. The main reason is both the M-mount lenses I have were busted and I have been too lazy to get them repaired. But actually, the larger reason is that I haven’t been shooting much of anything in over a year.

The introduction of the Olympus E-P1 reminds me that I have to get some of my money’s worth out of my cameras. Good dSLR bodies depreciate at the rate of 25% per year compounded. Photography with $5000 bodies gets expensive quickly!

So I purchased the 40mm sister of the lens I mentioned before and started to snap away—the fact that I can adapt this as an 80mm f/1.4 portrait lens on a E-P1 figured partially into that decision 🙂

I’ve been trying to take advantage of my recent move to SoMa to set up some way to share interesting discussions with friends. Since I didn’t want to kill my friends with my risotto just yet, that meant scheduling a dinner at a nearby restaurant suggested by an old friend but new neighbor Jonathan.

Just outside the restaurant, flackette met two friends Ryan and Stephanie. While they were catching up, I decided to practice trying to manually focus on their new pug, Frank, who resembles his namesake—delta a cut of CTO.

Reviews with perspective

Listening to Wired’s review of the Olympus E-620 (rated 6/10), an entry level dSLR I’m not the least bit interested in, when I got to this discussion on high ISO performance:

I say “in theory” because the E-620 doesn’t really do all that well in low light situations. If the room is really dark, it takes time focusing and it won’t take really good pictures. If you crank up the ISO level beyond about 1000, the images start to look really grainy which is typical of cameras with much smaller sensors

My ear perked up.

This usually means I’m being fed bullshit.

Hmm, let’s see what Phil Askey has to say about this same camera:

Turning the noise filter down to ‘Low’ should produce results pretty much on a par with the best in class, up to ISO 1600. ISO 3200 isn’t terribly pretty but it’s no worse than you’d expect for anything smaller than a full-frame 24x36mm sensor. [Plus listing the control over noise as being a advantage in the conclusions.]

See for yourself…

Grainy at ISO’s > 1000? I guess this depends on what your definition of ISO is. 😉

Electronic Pen configurator

Spending a half our messing with Four-Thirds matching simulator.

Olympus E-P1 with Voigtlander M mount lenses

The top one is a 50mm f1.1 lens (100mm in 35mm equivalent). Imagine that! The middle one is a lens I own (35mm f1.2) except mine is in chrome and needs to be fixed. The bottom one is the 35mm f1.4 NOKTON classic. I own the 40mm version and mine has an “S.C.” stamped on the outside of it, but pretty much looks like that.

All would require an adapter available from Cameraquest in L.A..
