Photographers' Formulary 01-0057 overview

  • 1Description

The Photographer's Formulary DK-25R Film Developer Replenisher, is used to extend the capacity of D-23 or D-25 from 4 to 25 rolls per liter.

As a developer is used, it's action is weakened by both the chemical reduction of the exposed silver halides in the emulsion and by the release of bromide ions into the solution.

The net results of reduced developer activity are reduction in the effective film speed and lower contrast.

Adding replenisher ensures normal developer activity and partially counteracts the effects of the increased bromide concentration.

The shelf life of the replenisher solution is six months.
