Abstract
We consider a new version of the Einstein - Podolsky - Rosen (EPR) paradox in which the measurements have limited accuracy, so that a photon number is specified only to plus or minus a macroscopic number of photons. In our example the minimum quantum uncertainty product for the two relevant conjugate quantities is itself a macroscopic photon number. This new version of the EPR situation is stronger than the original microscopic versions, which were based on the validity, now disproved by Bell experiments, of `local realism' at a microscopic level. The new version is based on the validity of `macroscopic local realism', which has to date not been questioned.
