Having fun and learning something in the process

Orlando Diary

Playing with my EP-2 tonight, I learned to appreciate one of it's nearly infinite number of built-in features: continuous autofocus with tracking. When you partially press the shutter, a big green box with small cross hairs poking out each side will appear in the center of the LCD, over the part of the composition that will remain in focus. Then, with your finger over the shutter, as you recompose the photo by moving the camera, the box will track that area, making sure it still stays in focus. This is very handy for close focusing and/or shallow depth of field with lenses set at their widest aperture.

Lucy Paw Out
Figure 1: Lucy with her paw out. The paw is the center of focus.
For example, in figure 1, I focused the E-P2 on Lucy's extended paw. If I'd taken the photo immediately at close distance, then I would have cut off a good portion of her head. Instead, I simply recomposed to bring her head and paw into the composition I wanted, then took the photograph. The paw remained in focus, with the rest of her fading into a pleasing out-of-focus effect.

Lucy Paw In
Figure 2: Lucy with her paw in. Her eyes are the center of focus.
In figure 2, Lucy decided she was tired of me taking photos of her paw, so she pulled it in. I was able to open the 17mm up to f/2.8, then refocus on her eyes, then recompose the image above.

The E-P2's automatic tracking, where the focus area moves around the screen, is phenomenal and fun to watch all by itself (yes, my inner geek is showing). It makes composition so much easier. Nothing is more aggravating to select focus, then have the point of focus shift behind where you want it when you swing the camera away from the initial focus point. This eliminates that annoyance. I just wish this feature were on my E-3.

So far constant autofocus tracking is very fast, a lot faster than I anticipated, and I believe a lot faster than when I first purchased the E-P2. There was a major firmware upgrade to the E-P2 earlier this year, and it more than likely helped this feature out quite a bit. It's something I'm going to leave enabled for the time being. One set of lenses it won't work well with are going to be any of the regular 4/3rds lenses adapted to the E-P2. This feature is for native µ4/3rds lenses only.

Finally, a little more fun with street shooting. Nothing monumental, just some photographs taken
one evening while out getting supper for the family.

Late Evening Smoothies

at Chipotles on Kirkman across from Walmart.

All photos were post-processed using Lightroom 3.2. The photo outside the smoothie shop was corrected for perspective. Lighroom's post-processing features are a joy to use as well.

Equipment Used
Olympus E-P2 and M.Zuiko 17mm f/2.8

cat-in-a-box channels greta garbo

So I'm sitting at my computer, when I start to notice a racket in back. I ignore it for a while until I hear a load "thump!", as if something had been dropped on the floor, followed by a lot of loud rattling. I turn around and see Lucy in the box just having a grand old time, rolling around and rattling that box a good one. I grab the GX1 and snap a few shots before she notices me and the camera, then leaps out and back into her chair (which used to be my chair before she decided it was her chair).

Just like caring for Katie my black Lab taught me about dogs, caring for Lucy is teaching me about cats. She finds me fascinating, as I do her. And she expresses great affection and love toward me without coaxing. I try to return the affection and love, but she is a cat, and she takes a bat at me on occasion, although I think that's just her being playful. She always has her claws in when she does that.

She sits next to me during the evening in her chair while I sit in mi…

vm networking problem fixed

Over the weekend I upgraded to Windows 8.1, then discovered that networking for the virtual machines wouldn't work. Then I tried something incredibly simple and fixed the problem.

Checking the system I noticed that three VMware Windows services weren't running; VMnetDHCP, VMUSBArbService, and VMwareNatService. VMware Player allows you to install, remove, or fix an existing installation. I chose to try fixing the installation, and that fixed the problem. The services were re-installed/restarted, and the virtual machines had networking again.

Once network connectivity was established there was exactly one updated file for Ubuntu 13.10, a data file. This underscores how solid and finished the release was this time. Every other version of every other Linux installation I've ever dealt with has always been succeeded by boatloads of updates after the initial installation. But not this time.

Everything is working properly on my notebook. All's right with the world.

sony's pivotal mirrorless move

I'm a died-in-the-wool technologist, even when it comes to photography. I have always been fascinated with the technology that goes into manufacturing any camera, from the lenses (optics) through the mechanical construction, the electronics involved, and especially the chemistry of the film and the sophistication of the digital sensor. It's amazing that the camera can do all it's asked of it, regardless of manufacturer.

Of all the types of cameras that I've really taken an interest in, contemporary mirrorless (again, regardless of manufacturer) are the most interesting because of the challenging problems the scientists and engineers have had to solve in order to build a compact but highly functional camera. In particular I've followed the sensor advances over the years and watched image quality climb (especially with μ4:3rds) to exceed film and rival one another such that there's very little difference any more as you move from the smaller sensors such as 4:3r…
