The most interesting thing about the 'King Penguin Conference', to me, was the depth of field, where all foreground birds were in crisp focus, leaving the remainder of the herd (?) as backdrop blur...what was the f-stop and focal-length, and was this planned?
Of course it was planned ;-)
Michael was shooting with the Hasselblad on that shot -- the birds at the foreground were probably 2-3 meters away. With that being the case, I would imagine that anything from f/4 to f/8 would give the suitable blur. I can't calculate the focal length for a medium format camera... maybe a 150 mm lens? or 80 mm 35mm equivalent?
