divided d 23 has been around for along time and is a standby .. people swear by it.
i sometimes use a hard working and slow working developer together, one develops the contrasts
and hard bits, the other the highlights and soft bits ... it takes a little goofing around but it is well worth
the risk of screwing things up ...
like with everything in photography, YMMV
and what works for one person, might not work for another ...
