Re: [APML] TP for terrestrial work

["Jim Ives" <flyboy9990@earthlink.net>]

Jerry that pretty much sums up what I found out about TP for normally
exposed photographs. I like the look it gives developed in the Technidol
liquid developer. I did some really neet normally exposed experiments with
it and D19 just for kicks too that were ment to have the high contrast look.
