Re: Developing sheet film in open-ended PVC tubes

Bill,

I have done stand development, and a lot of it.

Unfortunately there is no way to get completely even development with
stand development.

For some recent discussions on forms of minimal and stand development
to to http://www.michaelandpaula.com/mp/index_skip.html and look at
some of the topics under film development on stand and minimal
agitation.
