Photographed near the Crystal Springs Watershed in San Mateo County an hour or so before sunset. The stark lighting conditions attracted me to this scene, the beams of light in particular. [tags]California, San Mateo, landscape, photography, photo[/tags]

I’ve recently put together a collection of iPhone photos in my gallery. Photos included are from MacWorld 2007 in San Francisco and some recent studio photography work of product shots.

Dynamic range, in relation to photography, most commonly describes the light sensitivity range of a photographic medium whether slide/print film or a digital sensor. Unlike other definitions of Dynamic Range I think it’s important to discuss the relationship of the human eye and brain and what we determine as the standard of dynamic range. The eye is in all intents and purposes a sensor that can detect texture,

This was one of the first photos I took with my Canon 16-35mm ultra-wide lens. Using a film SLR I was able to capture the full effects of the barrel distortion (a type of perspective distortion) at 16mm. The result was the intentional illusion of the lighthouse tower leaning towards the moon. Over time I’ve developed a fondness for this type of lens distortion to create a sense of tension or place emphasis on a

A couple things happened this past week that got me thinking it might be a good idea to talk about landscape photography and choice of focal length. 1. I read “What’s Your Favorite Focal Length?” by Brian Auer I found the question that Brian posed to be a bid odd and never made a poll selection on his blog entry. The question of what your favorite focal length isn’t really relevant, just as as

 “In photography and optics, vignetting is a reduction in image brightness in the image periphery compared to the image center. Although vignetting is normally unintended and undesired, it is sometimes purposely introduced for creative effect, such as to draw attention to the center of the frame. A photographer may deliberately choose a lens which is known to produce vignetting. It can also be produced with th

“Barrel Distortion, in which image magnification decreases with increasing distance from the optical axis. The apparent effect is that of an image which has been mapped around a sphere. Fisheye lenses, which take hemispherical views, produce this type of distortion as a result of a hemispherical scene being projected onto a flat surface.” – Wikipedia Or… “Barrel distortion is a lens effe

This Sunday I woke up very early (4:40 AM) to drop my wife off at the San Francisco Half Marathon in which she was running. Being up before sunrise I thought it would be worth a try to go out looking for wildlife photo opportunities. Fortunately wildlife abounds here in the San Francisco bay area and it only takes a short drive to get to an area you might cross paths with wild animals. After dropping my wife off I de
