Re: altered dektol

["Gordon J. Holtslander" <holtsg@duke.usask.ca>]

Hi:

I'm happy with using LC-1, but I was struck by how similar this is to d-76
and dektol.

Using cheap ortho as a source of inexpensive continuous tone negative film
has given me many more photo opportunities.

I'm trying to see if I can find an easy more accessable way to use ortho
film for continuous tone so that other people without easy access to
accurate scales and chemistry can easily take advantage of this film.

Most people should be able to buy dektol and baking powder.  Other
developers will be less common.

I'll try kosher salt.
