I tested split development yesterday with Oriental WT FB VC and soft working glycin warm tone developer with postas bromide, and strong cold tone developer with benzotirazole.
I wanted to try to get warm whites and cool blacks. That didn't happen. I processed 3 minutes in the warm tone soft developer and 1 minute in the strong cold tone developer. The prints all came out slightly coldish warm tone with no color split.
What surprised me was in experimenting with strong cold tone developer first vs soft warm tone developer first. If I processed in the soft developer first the prints came out much softer without the depth to the black than when I processed in the strong developer first. Even though I kept the relative times the same. ! minute in the strong developer and 3 minutes in the soft developer. It was as if the soft developer inhibited the strong developer when I did the soft first. I did a water rinse between developers.
I don't understand. It seems like it offers further contrast flexibility but it seems if you want full black with split development you have to do the strong developer first.
Can anyone clear up why the color won't split and why the order of the developers makes a difference?
