Pushing TX400

HI Photogs,

I would like to experiment with Pushing Tri-X 400 to 1600 for some lower light applications.
Using Rollei Supergrain, the normal dev. time is 7 minutes. How many MORE minutes
do I add to develop TX400 pushed two stops to 1600?

I am guessing around 9 minutes but some informed opinions would be greatly appreciated.

Thanks!

Before you waste some film in testing read the section on pushing Tri-X on page 6.

You might like to try Tri-X developed in Spur SLD (http://spur-photo.com/some-information-in-english/). One of my ex-students has been getting impressive results at iso1000 with this combination with surprisingly good shadow detail and relatively moderate grain.

Bests,

David.
