There is a whole other essay to be written about why div devs give better local contrast than regular developers, but I have had one too many glasses of vin rouge tonight (welcoming my M4-p) to do this subject justice. Suffice to say that edge effects are inevitably enhanced when there is no developer available in solution, and the only developer is therefore going to be that adsorbed at the site in question or in adjoining areas of the neg.
