How to Make a Color Developer

Making the Developer Solution

• 1

  Determine how much developer solution you will be making. For most home processing ventures, 1 liter (34 ounces) of working solution should suffice.

• 2

  Refer to the dilution ratios for 1 liter of working solution. For your convenience, all manufacturers provide dilution instructions on the container.

• 3

  Measure out the correct amount of developer concentrate by pouring it into a graduated cylinder.

• 4

  Fill a beaker with the appropriate amount of water. While most working solutions can be mixed at room temperature, or roughly 68 degrees F, check the instructions on your container to be sure.

• 5

  Pour the developer concentrate into the beaker filled with water and stir until thoroughly mixed.

• 6

  Empty the beaker into a sealable plastic jug and screw on the cap.

• 7

  Write important details, such as the type of developer and the date it was mixed, on a piece of masking tape and place it on the container before using or storing it.
