Re: LITH films and halftone

[Matthew Hoffman <mhoffman81@comcast.net>]

Christine, here's a link to Liam Lawless's reversal process. I've used it
successfully for making enlargements of 4x5...without that pesky
interpostive, which, in my darkroom, at least, attracts all manner of
floaters like a magnet. With the initial exposure plus the flashing, you can
hit pretty much any density range you desire.
