Last week, I had the pleasure of joining with my buddy, Derek for some night photography in Downtown Atlanta. One of my favorite pastimes is photography, and more specifically I love long-expose photography. There is just something about it that is fun and entertaining for me. Night photography is not something everyone is good at, and to be honest, it is quite easy to do.

Don't get scared when I say this, but photography in any form is like a mathematical equation. It is all about compensation. With digital photography, you can easily change the ISO (or ASA) of each image you take. In the digital world, ISO is the CCD's sensitivity to light...it is mimicking the "film speed" in the classic film world. The higher the number, the more sensitive your film is to light. From there, you have the different settings with the lens, such as focal length (measured in mm) and focal distance (the distance you want in focus). What makes this easy for me, is I have captured images on film and compensating the lens just comes second nature to me. I often find myself looking at something and asking "If I were taking a picture of this, how would I shoot it?" That is the eyes of the photographer in me looking observing.

Long exposures are what makes night photography the best it can be. During daytime photography, you strive for the shortest exposure time...but in night photography, you want the longest exposure time. This is how I am able to capture the lights of the vehicles passing by. Doing a long exposure image is what tests your compensation skills the most. You have to be able to manipulate the ISO and f-stop (iris) of the camera to let in the amount of light that you need to "burn in" the image to film or CCD.
Have you ever tackled a night photography image? How did they turn out? What could you have done differently?
