These photos are a sampling of my photography portfolio. Being behind a camera
|
|
||||||
is my creative outlet, and I love being able to look back on past experiences.
|
|
||||||
|
|
||||||
The photos of Natural Bridges, Horseshoe Bend, and Shiprock come from a trip my
|
|
||||||
wife and I made to the American southwest in the beginning of 2018. It is an
|
|
||||||
exceptionally beautiful area of the world, and it is really hard to point a
|
|
||||||
camera in the wrong direction.
|
|
||||||
|
|
||||||
The shot of Horseshoe Bend is the classic shot. It was also the photo I put
|
|
||||||
the least effort into---the key was arriving just before sunrise (this helps
|
|
||||||
with both the huge tourist crowd and the light; the sun is behind me in this
|
|
||||||
photo). I mounted a 12mm lens, set the tripod on the edge of the cliff, and had
|
|
||||||
this photo about 10 seconds later.
|
|
||||||
|
|
||||||
Shiprock is a natural landmark in New Mexico on the Navajo Nation. It has
|
|
||||||
religious significance to the Navajo, so it is not possible to get closer than
|
|
||||||
a few miles away by car. When I took this photo in January, it had just
|
|
||||||
finished snowing the day before and the sky was overcast; it's unusual to have
|
|
||||||
a photo of Shiprock in fog like this. I could have composited out the telephone
|
|
||||||
poles, but I actually kind of like them as they give a sense of scale.
|
|
||||||
|
|
||||||
The photo of Owachomo Bridge is from Natural Bridges National Monument. This
|
|
||||||
photo involved about 15 minutes' worth of light collection at 18mm and f/2.8
|
|
||||||
(plus another hour or so of setup). I took multiple exposures and stacked them
|
|
||||||
using software to amplify the night sky against the noise of the camera sensor.
|
|
||||||
Natural Bridges is one of the best places in the world for astrophotography
|
|
||||||
because they go to great lengths to minimize light pollution.
|
|
||||||
|
|
||||||
The other photos are miscellaneous photos from various one-off projects. They
|
|
||||||
make good desktop wallpapers! I also enjoy taking portraits, but I've omitted
|
|
||||||
that part of my portfolio here.
