Response to PMK: is an after-fix bath in used developer needed if alkaline fix is used?

If you check page 19 of Hutchins book you will find that he uses Kodak's F-24. I find that with Tri-X I get a superior image to HP5+, since HP5+ has mostly chromegenic dyes and you will see no base relief image after development in a pyro developer. (Like on the back of a Kodachrome 25 slide.) HP4, although slower is IMO better also. But my preference is for slower films and Pyro developers. I use straight hypo myself, one pound to one gallon of distilled water. No rinse, no hypo clear, one hr. water wash, no hardener, since the pyro tends to harden the emulsion anyway. Pat
