Before we got in our kayaks (Hallwilersee in Switzerland), we had a quick photo session. Photoshop file made up of 15+ layers to create this high contrast, illustrative look. 100% non-destructive method.
Morning, storm clouds and overcast. Flat light.
2 bare flashes (1/16th?) on either side of subject slightly behind (on light stands).
1 flash behind/right of camera for slight fill on subject. I would have preferred a shoot-through umbrella on this flash but high storm winds prevented this.
