Radiant recently had the opportunity and challenge to shoot the Oldenberg “Flashlight” sculpture on the UNLV campus for Desert Companion magazine.  I say challenge because the shoot required an evening shot of a matte black sculpture, lit only by mixed ambient lighting, on a college campus that has students walking about.  So I packed up my tilt-shift lenses one Saturday night and headed on down to UNLV to see what I could do.

Being a weekend evening, I didn’t have too many bodies walking through my images.  I was also able to pull long exposures to yank some color out of the sky, courtesy of the reflected light pollution from the Las Vegas Strip.  Now the challenge was getting a three-story matte black object to maintain detail and color fidelity from top to bottom.  The area was lit with a mix of high-pressure sodium vapor, mercury vapor and halogen light sources…a perfect white balance nightmare.  However I brought along some flash heads and a battery pack so I could at least fill the shadowy sculpture with some color correct fill light, right?  Well, kinda.  I did a bit of light painting, but with the intensity of the light needed to light the black monolith, there was just too much flash spill onto the surrounding trees and cement.  So I went the multi-exposure, multi-white balance route.

A series of exposures were made for the highlights all the way to the shadow details that I’d later tone map in Photoshop (no, I don’t use tone mapping software, as I prefer to do it manually layered in PS).  Same thing for the various white balances, although much of the scene was lit under high-pressure sodium vapor lamps which are nearly impossible to white balance, due to their spectral output.  It’s light nerd stuff I won’t get into here.   Anyway, back at the office I processed all the exposures and pulled an under-, over-, and properly exposed frame from each composition.  I then layered those and used masks to tonemap the final image, which has greater highlight and shadow detail than any single exposure I captured.

All in all a great challenge and fun image to work on.  The image below is the magazine layout and unfortunately is quite compressed, so the detail is lacking.  I’ll post up a better shot soon.

The awesome LVSK8 art show is upon us again and I’m working on a new skatedeck design for this year’s show. Last year I did a hand-carved tiki (see it here), but this year I’ve put much time and effort into researching how to get a photographic image onto wood. The answer seems to be water-slide decal transfer paper, which I have yet to try. I just ordered a batch online and will make some test prints to transfer to an old deck before I do the final piece.

I figured the show’s deadline was a good excuse to complete a half-finished project that has been collecting dust in the garage for about two years. Late last night I finished building the motion rig for shooting moving cars. Depending on what camera angles and distance away from the car I desire, I have some more support arms to fabricate, but this rough start is functional for some shots. I hope to post a blog post and video strictly on this rig sometime. It uses some steel tubing, insanely strong magnets, fence hardware, and a Super Clamp.

Anyway, here is a sneak peak at the theme of the deck, although probably not the final shot I’m going to use. (Keep clicking on the image to get into a higher res version two pages from here)
