There is no Bromide in either Part A or Part B.
Based upon the Massive Development Chart I selected a ratio of 1+1+10 for 8min. at 68-F. Next time I will try 1+1+8 and then try 10 minutes if necessary.
Beutler's HD #105 is my developer of choice for 35mm slow films - right now.
Sorry, I did not mean to imply that the stock solutions contained bromide but meant that acutance developers in general depend on the
local buildup of bromide in the emulsion to restrain development. This bromide is released by the emulsion during development. It is this restraining action in part that is responsible for the edge effects
However, Willi Beutler in his book, stated that 5 to 10 ml of a 1% solution of potassium bromide could be added to every 500 ml of working strength developer. Another common additive advocated by Geoffrey Crawley is a
small amount of a very dilute solution of potassium iodide. Typically 2.5 ml of a 0.001% solution is added per liter of working solution. This is said to reduce flare and increase sharpness.
Also from Beutler's book, the recommended dilution is 1 part A +1 part B + 8 parts water. Somehow in last few years this has been transmogrified to 1+1+10.
The number #105 often associated with the Beutler formula is the number of this formula in the Anchell book. It has really nothing to do with the formula and Beutler certain did not use it.
