So how do you shoot a medical marvel that is an absolute tech wonder, producing and providing highly detailed maps of the interior of the human body, but, on the outside, sort of looks like a big refrigerator with a hole in it?
The only sexy thing about this machine, visually speaking, were the blessedly intense, focused red beams that created the cross hairs used by the technicians to “aim” the scanner. The patient slides into the machine, and the device is aligned with assist of these beams. Turn the lights off in the room, which is one of the first things I often do when I walk into an environment, and you basically have the picture below.
Once again, up pops the irony of being a “flash photographer.” At any given moment, the most important light you deal with is the ambient light. What exists, is the first question you grapple with. Then, and only then, after you wrangle what exists and what role (dominant, background, fill) that light will play in the photo, can you mess with flash.
So in the darkness, with a D800E set at f5.6 at ISO 400, I sorted out a shutter speed of 4 seconds. Which was fine, as my “patient” wasn’t going anywhere. Of course, in this iteration, I’ve got a red light and no context, or information. Luckily, I had a wall behind me, flat and white. I turned the head of my SB 910 backwards into the wall, and shifted my color balance to incandescent. That flat wash of light off the wall, un-gelled, and plain white, defined the machine, and the tungsten WB gave it a bluish cast, which I felt would work better than dead bang white. One flash, on camera, re-directed, gave me color, tone, context and editorial content.
Still couldn’t turn on the overhead fluorescents to provide the background illumination, as their overall, blah quality of light, filling the room (which is what they are supposed to do) bleached out the intensity of the red aiming beams, and those red beams were the anchor for the picture. So, I kept the room dark, and flashed the background of the photograph with two SB units, each slightly warmed with a CTO (color temperature orange) gels. I believe the gels were fairly mild, maybe a quarter cut, or 25% of the truly warm tone a full conversion gel would have presented. They are placed, TTL, in Group C, which is always the group I use for the background lights in any photo. I switched my on camera flash to double duty, acting as a TTL main light, and the commander for the background fills. Done.
But, was I really done in the darkness? As is said in The Game of Thrones, the night is dark and full of terrors. I was moving fast, needing to clear the room of my gear so they could get back to scanning. I had a nice picture, one I knew the client would be happy with. So I plunged ahead.
Now, I love Manfrotto stacker stands. I just don’t love them when they’re actually in my picture. Doh! They had to be retouched out in the final TIFF sent in for the book. As I always say, whenever you are feeling lock solid and dialed in, think again, and check again.
In the darkened hallways of my mind, the ghost of Numnuts is cavorting about and laughing, and that laughter echoes, as it has for my entire career.
