Developed this print without developer - used the
multigrade Ilford RC paper. A solution of baking
soda, sodium carbonate (washing soda), or ammonia
(bad fumes) changes the ph and creates the image.
With developer incorporated paper, you get a more
normal color since it's made to use an "activator"
that works the same way. I don't know how stable the
color is or exactly what's happening since this paper
(Ilford multigrade IV Deluxe RC) apparently isn't
developer incorporated
