I usually you may have noticed,spend time watching the hi jinx at KRON. But,I was watching ch5...then go back to KRON to make sure I wasn't imagining that KPIX news stories- all of them- were in a much sharper HD full 1080 I would say. KRON's seemed to be done with old 720 or even Iphone. Not as sharp and darker. Some were not HD at all.
Either KPIX has real cameramen or they give reporters the best camera's around and teach them how to use them.
