3 Light AB setup, 1 gridded strip light 45 degree behind subject to the left, AB800 in softbox directly in front for fill, AB800 beauty dish camera right for main. Strobes fired with Pocket Wizards.
Each person/dog was shot on grey background and removed in Photoshop and placed into the final shot. Lots of adjustment layers, dodge/burn on the final composite.
Shot with my new favorite lens, the Sigma 50mm 1.4.
