Mixing Kodak D-76 Powder into Stock Solution | Developing Solutions

This very basic skills video shows how to take D-76 powder and mix it into stock solution for use. Here are some key takeways from this video: 1- Follow the package instructions exactly. Chemistry requires exact procedures to ensure safe chemical mixing and proper chemical performance after the solution is mixed. 2- Do not cut the larger package into multiple smaller doses and mix those. The larger package is compound-balanced for correct developer stock solution creation at the prescribed final volume -- in the case of the package in this video, one U.S. gallon. Cutting it into smaller powder doses will almost certainly cause the concentrations of constituent compounds to be in improper ratios and that will affect chemistry performance. 3- This video demonstrates how to make a STOCK solution from powder. The stock solution can then be used as-is and, afterward, returned to the stock tank for reuse. The stock solution can also be cut into a one-shot working solution. If you see a developing such as D-76 1+1 that means one part of D-76 to one part water -- for instance a 1,000 milliliter tank would require 500ml of D-76 and 500ml of water in that scenario. A 1+3 concentration would need 250ml of D-76 and 750ml of water. Diluted D-76 cannot be remixed with stock solution and needs to be dumped after use.
