When I was in Seattle for my “Shoot Like a Pro” Tour, before the seminar kicked off in the morning, Brad and I went just outside the convention center so I could create some real shallow depth-of-field backgrounds I could use in Compositing. I did this mostly because I hate how it looks when you take an in-focus background and try and “fake it” by adding a massive Gaussian Blur or Lens Blur filter in Photoshop.
Above: I had Brad stand in the street, and I zoomed-in fairly tight on him with a 70-200mm f/2.8 lens, at f/2.8 so the background would be way out of focus (as seen here). Once I was focused on Brad, I would hold the shutter button half-way down to lock the focus on Brad, then I would give Brad a signal and he would walk out of the frame (that’s Brad walking out of the frame above).
Above: Once Brad was fully out of the frame, I’d just press the shutter button the rest of the way down and take the shot. Mission accomplished — a realistic shallow depth-0f-field background.
