Portraits with shallow DoF & high-speed sync flash
High-speed flash sync (HSS) has two primary uses – being able to get to a fast enough shutter speed to stop action, and for shallow depth-of-field. Other than that, I rarely stray higher than max flash sync speed. So for me, it is a conscious decision to go to HSS. Or not.
For these playful portraits of my friends, Irene and Michael, I wanted to use the shallow depth-of-field with specific intent. Irene and Michael are at the core of a performance group called the Modern Gypsies. Their official website: Modern Gypsies productions. I have photographed the Modern Gypsies several times over the past few years for their own promotion. Since they are always in outlandish costume then, I wanted to photograph their portraits as themselves, sans costume and stage make-up. For this photo session we met up in their home turf, Brooklyn.
Straight-forward portraits wouldn’t be as true to who they are – I wanted to give a sense of some of their crazy inventiveness.
The idea I came up with was to have Irene’s portrait slightly surreal – Irene with her trademark see-thru violin … but I still wanted to include Michael. Some of his acts (such as PinkMan) has him bouncing around on stilts while in costume. I wanted to include him, but still have this be a portrait of Irene. By using a wide aperture (f/2), I was able to throw him out of focus in the background.
Camera settings and photo gear (or equivalents) used for this photo session
- 1/1,000 @ f/2 @ 100 ISO
- Nikon D4
- Nikon 35mm f/1.4G / Canon 35mm f/1.4 II
- Westcott Rapidbox – 26? Octa Softbox
- (2x) Nikon SB-910 Speedlight controlled by PocketWizard FlexTT5 Transceiver & AC3 Controller
or alternately, the Canon 600EX-RT Speedlite controlled by Canon ST-E3 Transmitter
- (2x) Manfrotto 1004BAC – tall light-stand
I used two lights here – a speedlight in a softbox on Irene; and a direct, unmodified speelight on Michael in the background. I wanted that shallow depth of field, hence an f/2 aperture. Since the f/2 aperture implied a fast shutter speed – we were shooting outdoors – we were in high-speed flash sync territory. We needed that 1/1000 shutter speed to freeze action. (Since the available light was the dominant light source, the flash wouldn’t be able to freeze the action on its own.)
The pull-back shot above shows the positioning of the two lights, with Michael standing more or less where Irene would be in the final sequence of images.
