I have been trying to photograph the progress being made in construction of the new 1 World Trade Center here in New York. All my photographs are ruined because I get swervy lines on areas of high-detail such as windows. What causes this? It never happened with film cameras. Is it that digital cameras cannot support such detail? I have been using 6 MP. Would increasing to 10 MP help? I have no other problems except with skyscrapers. Any help would be appreciated.
