Profoto B1–Nikon TTL: Field Test

Aug 18

In Field Test at 7:31am

I recently was fortunate enough to be allowed to play with a beta version of the Profoto Air Remote TTL-N units. That means, in short, the Nikon version of controllers for the already renowned Profoto B1 units. The Canon models have been out for a while, and now the remote for Nikon hits the market on Sept. 15. Hit this link for the complete skinny and specs

So, here’s the good news. My first frame shot with the unit was bang on in terms of exposure. (Which I figured was pretty good, as, it being the first time in the field with them, I really didn’t know what I was doing, or what to expect.) But, despite my first time fumbling, the unit had an exposure lock right out of the gate.

I’ve been asked many times, “Why bother with TTL? Why not just go manual?” Perfectly legitimate questions. There has always been an air of mystery and uncertainty when messing around with TTL. It is the equivalent of opting for a meander in the enchanted forest, staring misty-eyed at the branches and leaves dancing in the wind, instead opting for the chainsaw efficiency and known end result of the lumber yard.

And I live in the manual world, quite often. (Don’t tell Hobby!) Always a good option. But, back at the dawn of TTL, when I started to stand upright, and looked down to discover I actually had opposable thumbs, the whole idea of flashes talking to each other, and the camera, was quite intriguing. I had been through the Vivitar wars (no one survived) trying to make “yellow mode” work as I chased Cher out of Studio 54 into her limo. I had developed a pretty intuitive sense of f-stop relative to the nuclear blast of some of the potato masher flashes I grew up with. (Sunburned subjects, anyone?) I was also reasonably quick about doing long division with guide numbers in my head as I was trying to conjure a composition.

But Christ, it was a lot of hoohah and seemingly unnecessary work! So, when the TTL sun came up over the primordial swamp where I had been sitting in the ooze, eating bugs and waiting for my fins to become legs, I was appreciative. It all started with the Nikon SB-24, which got it right about as often as the Knicks have made it to the NBA finals in the last 20 or so years, but held the maddeningly elusive prospect of an intuitive flash future. Fast forward to now and the SB 910, which gets it right most of the time, and you can see we’ve come aways.

And now, another part of the journey. Bigger flash, done TTL. The Profoto B1 has taken the market by storm, and rightly so. It is a simply, beautifully engineered light. And now, coupling it with through the lens exposure technology, which is now integrated into the already rock solid, dependable Air Remote signaler, well, for me, it’s just about cause to skip and go naked.

For my test, I went into the woods out in San Diego, and hung the beautiful ballerina Jennifer Curry Wingrove from a tree. (I mean, why wouldn’t you?) Jen is a great sport who once went on pointe for me on the counter of a diner in Coronado. She runs a pilates training studio in San Diego now, called Pilates on Park, and has added silk flying to her repertoire of skills.

First job was to get the damn silk in the tree. I’m not exactly Peter Pan anymore, but on location, if I need to get something done that on the face of it appears to be remarkably stupid, I tend to do it myself. So, up the ladder and onto the tree branch (a substantial tree branch, I might add) I went.

I was confident though, as I had the redoubtable tandem of Rob Stephen of Photo Monkey in San Diego, and the maestro of rock and roll, Alan Hess, holding the ladder.

Then, I just do what I usually do in the field. I move things around until they start to make sense. Or don’t make sense. Out here in the woods, I wasn’t up for blending things and making the forest look like a slightly accelerated version of itself. I put warming gels on my background lights, and lit up some trees and grass, just to play with the flashes and draw down what would have been a completely colorless sky. Reality was not my objective here. The inputs the flashes are making into the scene are not subtle, or reality based.

Here’s the basics of where we started:

  • Camera Body and lens? Nikon D4S + 24-70 AF-S lens
  • How Many Lights? 4 B1’s total
    • 1 – Main Light with a RFi Box as Key light positioned @15-20 ft  away from subject on a stand, @ 15 ft high. Soft box was a 1′x3′ strip light with an egg crate to control the spill of light.
    • 1 – Background Light positioned behind subject on the trail about 30 ft away on a stand, @4 ft high
    • 1 – Side light camera right on a baby stand, @40 ft from the tree it was lighting
    • 1 –One on the ground camera right, @ 20’ from object it is lighting, i.e., tree trunk. This unit moved around to different positions, as I experimented. It eventually moved to accompany the first background light, giving me a substantial pop of light deep in the frame, behind the trees. 

We dragged a generator and wind machine out there with us, which ended up not working out. The existing wind and heaviness of the silks defeated us.  Things moved around a bit as we tweaked things here and there, but this is where we started.

Again, the good news is our main problems were the bugs, the poison sumac, the encroaching darkness and trundling a generator a half mile into the woods and not using it. The lights worked great. I was happy to see they responded in very similar fashion to my Nikon speed lights. On the pro camera bodies, in the Nikon system, there is a checkoff (E4) where you can dictate to the camera to integrate your TTL flash computations for “background only” or “entire frame.” This allows you to direct the flash compensation independently from the EV inputs on the camera. The B1′s behaved the same way. (The new version of the D800 camera, the D810, now has this feature as well, thank goodness.)

Rob and Alan proved adept at tossing the silks into the air, which is where we ended up, after the wind machine proved to not have enough oomph.

There’s lots of experimenting to do with these and the possibilities for the future are pretty endless. But, across the board, these units rock. Battery life is excellent. The design of both the flash and the remote is simple and straightforward. The TTL response was predictable, and controllable. I had control of all three zones, and they all responded to commands. This is exciting stuff, and there is definitely more tk here…….

As I usually mention when teaching flash lighting, the most important light to observe and work with is not represented by that carton of flashes in the trunk of your car. It’s the ambient light level you encounter …

A bright light just went out. Robin Williams could speak faster than most of us can think. And when he spoke (often in tongues) we laughed, long, hard and well.

Only photographed him once. Typical of his irreverent whimsy, …
