In commercial photography it is the duty of the photographer to not only provide the client with images that promote but also transform the product into something that captures the attention of the customer. Recently I was given the opportunity to work with Login, Inc. - a provider of Business Voice, Internet and Colocation services in Tucson Arizona. They operate three Data Centers located in Arizona and Colorado - fascinating places only techies can truly appreciate.
Data Centers typically contain racks and racks of expensive, high tech computers and equipment in windowless, secure, cold rooms lit by blinding florescent ceiling lamps and encased in the cacophony of sound from power generators and cooling fans - isolated from the torturous, dirty world outside. Matt J. Ramsey, the Co-founder and CEO of Login, being the astute and artistically sophisticated gentleman that he is - had admired my long exposure astronomical work and knew that such techniques could be used to document his data center for promotional purposes. My job was to make this sterile, self-contained world somehow look beautiful and inviting. I happily accepted the challenge.
Now I had done this sort of thing before - in the darkened studio and out in the desert at night - using shielded flashlights with colored gels to "paint" the scenes to my liking. This is a slow and painful process, as you must determine - empirically - the duration and intensity of the light laid down on the subject. Trial and Error - hour after hour of experimentation for a payoff of just one decently painted and properly exposed image.
This picture is the result of a single 12 minute long exposure made out in Saguaro National Monument West one night in October of 2003. I used 5 different mini-maglights with shields and colored gels to create the "painted desert" effect. (With apologies to my idol - William Lesch)
For the Data Center images, with the florescent lights turned off, I used the power and signal LEDs native to the equipment in the racks as the primary light source. I gauged my exposures as to allow these lights to provide most of the ambient illumination. For those areas that remained dark (or darker than I thought appropriate) I dropped back to my light painting experience at night in the desert and used gelled flashlights to add some artistic nuance and color to the scene. Exposures were typically 60 seconds at F/4.5 and ISO 400. Below are some of the more colorful results.
A special thanks goes out to "Heather" - the model in the one picture with a person in it. She expertly stood absolutely still for over a minute while the camera shutter was open and I painted her with a flashlight. Oh - and for those of you that are certain to ask - Yes - I was in frame in every single shot here. Why am I not visible then? I never stood in one place long enough to register "on film":-)

Skyfire
Well - I'm at Kitt Peak National Observatory for the next three days. Its offically "down-time" for the summer monsoon season and we have the next 4 weeks to perform upgrades and maintenance on the the telescopes.
This afternoon however, the monsoon storms began rolling through the valleys surrounding the mountain and I was treated with a SPECTACULAR show of lightning and clouds.
Around sunset the rain showers in the valley west of the mountain became backlit with the setting sun and provided some very interesting telephoto abstract imagery.

Later, as the storms intensified I witnessed a violent down draft south of the small town of Sells, AZ that produced a large dust storm - and what appeared to be a rain shaft not unlike the look of a tornado . . .

As it got darker, the lightning became so intense south of the mountain that you could point your camera just about anywhere and with a couple of seconds capture astounding strokes with the observatory domes in the foreground. All images shown here were made with either a 200mm or 400mm lens. Exposures ranged from 30 seconds to 2 minutes.

M51 from the backyard
Well it finally cleared up tonight so I could test my 6" refractor and autoguider. It was a little brezzy but it didn't seem to affect the setup. I used ISO 800 and the telescope at F/9 for an effective focal length of about 1370mm. 8 ten minute exposures combined to produce the image below - taken through a LPR filter of course (my backyard is VERY light poluted). Click on the images for a larger view.

Long Glass
Well - finally got all the stuff I needed to test the 6" refractor's suitability to astrophotgraphy. I ran a couple of preliminary tests on M3 last night - five ten minute long exposures at 1370mm using a newly acquired Lodestar autoguider. Results were extremely promising. Stay tuned.
