Hi Phil,Originally Posted by philsweeney
What film are you working with and how are you processing it? I have no problem getting enough negative contrast using HP5+ or TMAX 400 and PyroCat-HD with non dichromated sodium citrate. Looking at my paper curves of toned kallitypes I'm seeing an ES of about 1.28 (I still have a few curves with other toners to plot.). I've not tried to proof with AZO so I'm not sure what advantage that you gain there.
