“What medium—gum, multiple gum, bromoil, platinum, bromide, chloride—is
most popular today?”
“Bromide and chloride are the most popular. That this is so is probably
because they are easier to use; but there are very earnest workers—some of
the best—who insist on using the processes which give a greater range and
greater possibilities of quality, such as bromoil, gum, and gum platinum.
I would say that these processes are more popular than they used to be.”
