Photo of the Blood Moon with some stars. Taken one cold evening on January 20th 2019 from Kenneth Hahn State Park in Los Angeles. Canon 5dmkIII | 70-200mm f2.8L. During a total lunar eclipse, Earth completely blocks direct sunlight from reaching the Moon. The only light reflected from the lunar surface has been refracted by Earth’s atmosphere. This light appears reddish for the same reason that a sunset or sunrise does: the Rayleigh scattering of bluer light. Due to this reddish color, a totally eclipsed Moon is sometimes called a blood moon. Unlike a solar eclipse, which can only be viewed from a relatively small area of the world, a lunar eclipse may be viewed from anywhere on the night side of Earth. A total lunar eclipse can last up to nearly 2 hours, while a total solar eclipse lasts only up to a few minutes at any given place, due to the smaller size of the Moon’s shadow. Also unlike solar eclipses, lunar eclipses are safe to view without any eye protection or special precautions, as they are dimmer than the full Moon. The reddish coloration arises because sunlight reaching the Moon must pass through a long and dense layer of Earth’s atmosphere, where it is scattered. Shorter wavelengths are more likely to be scattered by the air molecules and small particles; thus, the longer wavelengths predominate by the time the light rays have penetrated the atmosphere. Human vision perceives this resulting light as red. This is the same effect that causes sunsets and sunrises to turn the sky a reddish color. An alternative way of conceiving this scenario is to realize that, as viewed from the Moon, the Sun would appear to be setting (or rising) behind Earth.

The Iconic 6th street bridge in Downtown Los Angeles is finally being torn down this weekend. The 101 freeway is being closed for a whole weekend to ensure safe removal of the 84 year old viaduct. The bridge has been used in countless films, TV show and music videos over the years and is instantly recognizable as somewhere in LA. It spans two freeways, the LA river, two different sets of rail tracks and numerous streets. A poor choice in concrete when this bridge was built in the 1930’s lead to chemical reaction some 20 years later causing the structure to weaken, experts estimate that the bridge would have a 70% chance of collapsing in a major earthquake. It is because of its impending demolition that I’ve took some time out and taken a few shots while I still had time.

Just this past weekend I finally got to visit Victoria Beach Tower near Laguna Beach. I had been procrastinating on this location for a couple of years now and never seemed to get down there, weather, commitments and traffic have always seemed to get in the way, coupled with the 150 mile round trip for one shot, if I went down there.. The conditions had to be right. (more…)
Welcome to Graham Gilmore Photography V2.0.
Its been a little quiet for me in recent weeks both online and photographically so I have been working on my latest website update, as the (slightly ;)) cold spell continues here in Southern California I have been busy working through my stock of images and compiling what represents me best at this point in time as a photographer, during this process it became obvious that my website wasn’t up to the task of displaying the amount of work I now have to show, over the last couple of weeks I have been working on this and now present to you grahamgilmore.com Version 2.0!
Took a last minute chance yesterday afternoon and headed out to try and catch something of the solar eclipse from here in Southern California.
