Jim,
the closest one can approximate the effects of stand development with rotary processing is by using a 2-bath developer. Development happens very quickly in the second bath, with the developer- hungry highlights exhausting their local supply of developer absorbed in the emulsion, while the shadow areas continue to develop until the developer there is exhausted, too. This disproportionate development is sometimes referred to as compensating development. And since development is completed so quickly, there is little time for the developer to migrate between regions of high and low densities, so acutance can be very high. This is the only way I use Hypercat with rotary development.
