There has been much discussion on various forums for over a year about the veracity of a picture Tony Immoos took from Hall Road in Turlock showing Half Dome, El Cap. etc. Here is a short video taken from the very spot the still picture was taken. Look at the picture here first then the video: http://www.flickr.com/photos/trimmoos/3294080995/
Please bear in mind that he had a 2billion megapixel DSLR and I was using a 1 mega pixel Sony VX2000 video camera.
