I always do this for the developers I mix up from powder. I let them
sit at least overnight. I find it makes a huge difference esp. if
you want consistent results, this is for b/w. I do this for both film
and paper developers.
I also usually always put in a small amount (5-10ml) of used
developer into the new stuff (regardless if I used liquid concentrate
developer or one made from powder). Again this is for b/w developers,
especially for paper. If I use really fresh developer in the machine,
it takes about 10-15 prints before things "get going".
In Germany this is called "using a starter". In fact AGFA also made
specific "starter" chemicals for their colour processes as well, but
again mainly for paper development in the machines.
Love,
Snoopy
