Another application for the zoom blur is doing a tight person zoom blur. Picking a bg makes a difference and I like having one colorful and even. If you have gaps in color will look odd once you zoom.
zooming speed is also important for getting some detail in the center, this was hand held but best to mount on tripod. There was overcast and I was just doing one so the neutral density filter didn't come out. Remember to set the metering to Tv or manual !!
Comments welcome and much appreciated
