We review the argument that latent image formation is a measurement in whichthe state vector collapses, requiring an enhanced noise parameter in objectivereduction models. Tentative observation of a residual noise at this level, plusseveral experimental bounds, imply that the noise must be colored (i.e.,non-white), and hence frame dependent and non-relativistic. Thus a relativisticobjective reduction model, even if achievable in principle, would beincompatible with experiment, the best one can do is the non-relativistic CSLmodel. This negative conclusion has a positive aspect, in that thenon-relativistic CSL reduction model evades the argument leading to theConway--Kochen "Free Will Theorem".

Connecting the dots: Mott for emulsions, collapse models, colored noise, frame dependence of measurements, evasion of the "Free Will Theorem"
