STANDARD is the basic film developer in SPRINT's B&W processing system. All solutions for this process are in liquid concentrate form: 1 liter of STANDARD concentrate will make 10 liters of working solution to develop at least 50 rollsof film, or enough replenished solution to develop 110 rolls. STANDARD inhibits agitation streaks, does not block up highlights with over-development and does not contain Metol which can cause skin rashes!
