While parked within photo range of a herring ball it is important to remember that humpback whales have and excellent sense of their environment. They will surface close to the boat but they are aware that you are in the area. The other important point is not to be moving while you are waiting or the whales will not know your position. In this case the whale was close enough that it was impossible to focus the camera and those with long lenses were lost. The June 5th posting is a much better distance.
