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":-)

Star testing the Canon 14mm and 17mm TSE
Well - my visit with the two Canon L series lenses from CPS is going to end tomorrow - have to send them home. But - before I do I have to give them the ultimate test for any optical system capable of focus at infinity - the star test. The most severe test one can perform on a telescope or lens is to see how it handle point sources across their field of view - especially in the extreme corners of the field.
So - I took them with me up to mount Lemmon Observatory last night. I had to help the CSS astronomers Steve Larson and Ed Beshore work on their new 1 meter telescope and decided to take a few portraits of the new scope with the 14mm . . .
When it finally got dark I setup the camera and lenses on a tripod and made a couple of short exposures at high ISO and the lowest f ratio for each lens - doing critical focusing on a star near the middle of the field using the live view mode of the 5D mark II body I employed for these final images. I then examined the stars at the corners of the field of view (highlighted in the full frame image.) Note that coma is apparent in both lenses - not unexpected and not as bad as other lenses I have. All in all the 17mm performed best and it is most likely my next lens purchase.
