Toothbrushing Illustration How-to
I recently published a life-hacker style post about my toothbrushing routine on another blog. I decided it would help to have an illustration, and figured, I’m a photographer, I should be able to provide just what I need.
I visualized what I wanted in my mind, and then thought about how to achieve that image. I decided a shot of me, toothbrush in hand, mouth full of toothpaste, grimacing into the bathroom mirror would be just the shot.
But mirrors are notoriously reflective, making it very difficult to get shot of one without also seeing the camera, off camera flashes, etc. And bathrooms tend to be lacking in spaciousness. Not to mention that the shot I was visualizing shows me face on, looking directly into the mirror, something like the picture below:

Arizona Poppies

A close up of the yellow flowers from the previous entry. We typically get wildflowers in the spring in the desert. The beauty of the display depends upon how much winter rain we receive. The rains this summer have brought out a beautiful display of these Arizona Poppies. You can even see them covering the side of mountains with their brilliant yellow petals.

Trail Head

This trail head is made more inviting by the green plants and yellow flowers along its border. It leads to a stream that you’d think would be cool and refreshing, but instead is warm and a bit muddy. The warmth comes from the desert heat, the mud because when it rains the stream becomes a muddy torrent that closes the road into/out of the park.

The Green Desert

We’ve continued to receive rain since the flooding, and the desert has transformed from brown to green—so much so that you can see the green on the mountains. This is Catalina State Park, north of Tucson, which has received almost twice the amount of rain as it normally does by this time of year. Note the gray clouds ready to drop more rain on the mountains.

Cartwheeling

The Geico stunt plane pilot tumbled his plane through the sky for much of his show. He must have had quite a headache from pulling all those Gs - both positive and negative.

Flood, part 1

In October of 1983 Tucson had several days of rainfall. The washes and normally dry rivers filled beyond flood stages, damaging bridges and several homes and apartment complexes. 10 years later we had a similar event, and even more damage in monetary terms. This past weekend we had a large amount of rain dropped on the nearby mountain ranges, which drained into these washes and rivers. Due to structural improvements on the banks and to bridges, we had less damage, even though the amount of water that came through was greater than either of the previous flood events.
The image above shows one of the washes flowing bank to bank, looking north to the Catalina Mountains.

Sabino Canyon Cactus

1/800, f3.6, 18mm, iso 100
This image is a bit soft - should have stopped down and decreased the shutter speed - and I cropped the prickly pear in the foreground too close, but I still like how it turned out.

Sabino Canyon Nursery Tree

1/160, f8, 21mm, iso 100
It is not uncommon to see a relatively young (no arms yet) saguaro cactus growing right next to a Palo Verde or Mesquite tree in the Sonoran Desert. These trees are called nurse trees because they provide shelter to the slow growing saguaro as it matures. A healthy saquaro can live to be 150 years or more, outliving its nurse, which is why you don’t see this relationship with larger saguaros.
This nurse tree, a Mesquite, seems to be running a nursery with 6 saguaro cactus under her branches.

Sabino Canyon Sunset

This image was taken on New Year’s Day, 2006. We had a great hike, and cool weather - but not at all cold. The sunset was spectacular, and I had a fun time capturing it.

Sabino Canyon in Black and White

This conversion was done in iPhoto using the Adjust HUD to control saturation and add a slight blue tint by changing the white balance temperature.

A Digital Photographer's Worst Nightmare
If you are shooting film, you have to protect that film. You make sure it is completely rewound before removing it from the camera. You worry about sending it through the X-ray machine at the airport. You dread someone opening the door of the darkroom while you are developing, and you pray that you don’t have the “new guy” processing your precious prints at the lab.
As a digital photographer I am blissfully unconcerned about those issues. But I have my own fears to face. Hard drive failure and no back-ups (note to self, make sure my back-ups are up to date), losing a CF card, or having a CF card go south.
That last one hit me last night.

I like this one for a number of reasons - the lines, the texture, the light, the juxtaposition of the organic lines with the geometric lines, the color.
But I am biased since I took the photo. What do you think?

I used the flash to “control” the shutter speed and get just the light from the street light instead of blowing that light out and seeing the rest of the parking lot.

Sorry for the view up my nostrils. This was taken with the keychain cam on the way to work this morning, and enhanced with Picasa. I’m pretty impressed with what it can do given an admittedly limited amount of information to start with.

My second image for the challenge. Still using the 640x480 pixel keychain camera. It only interfaces with Windows, so I am playing around with Picasa for editing.
This one used “I’m Feeling Lucky” in the Basic Fixes tab, a small saturation boost and an application of “Warmify” in Effects, followed by some Soft Focus.
I like how it turned out, given the quality of the original image.

So I’ve taken the challenge. Here is my first photo, taken with a 0.3 megapixel camera on a cloudy day at the University of Arizona.
I know this is Low End DSLR, but I ride my bike to work and carrying all that equipment is a bit too much (since I’m already carrying my laptop, change of clothes, and lunch).
I’ll get some DSLR shots in on the weekends…

30 Day Photo Challenge
John Koontz sent me an email this weekend that I just got around to reading:
“I came across your blog today and thought you and your readers might be interested in a photography challenge we’ve started. We’re trying to take and post a photo every day for 30 days. We’d love it if you can join us. All the info can be found here.”
Sounds like it might be fun. I might join in starting on March 1.
