It produced an interesting result - with the horizontal line acting like a divider. Do you actually move in towards the object or does your camera do it for you? Mine doesn't seem to allow for this - unfortunately!! Thanks for entering it into the challenge. Cheers .
@robz Hi Rob. I zoomed out from 70mm to 28mm. I believe any camera that has a zoom function will do this. You have to have a way to stabilize the camera and a long enough exposure to have time to zoom. Whatever is in the center of the shot will stay in focus and everything else is in motion. I have tried zooming from 28mm to 70mm but the center of focus changes and its harder to get anything in focus.
