Response to Getting shadow detail out of TMZ3200

from John Hicks (jbh@magicnet.net)
Switch developers. Go to a speed-increasing developer such as T-Max, Xtol 1:1, Microphen, Acufine etc.

Bear in mind that the "real" speed of TMZ is EI 800-1000, and that no matter what you do you're going going to significantly increase shadow density, but even if you gain only 1/3 stop in real speed by going to one of those developers that's 1/3 stop more real speed than you had before. If you expose TMZ at an EI higher than 1000 or so and develop accordingly, you're pushing, which is defined as developing to higher contrast to try to compensate for underexposure so the neg will print on a fairly "normal" grade.

Comparing TMZ @EI 1600 negs to TX etc negs exposed and developed normally _should_ show somewhat less shadow detail/density in the TMZ negs.

Try this: TMZ in Microphen 7'30"/75F EI 1600.

Before using TMZ or Delta 3200 at EI 800 I'd much rather used HP5+ in Microphen, which gives EI 640 for _normal_ contrast and speed, unpushed.
