Herb,
I have opened and resaved the files with Photoshop to use compression on the TIFs. Maybe that's the issue?
The first set of conversion settings is as flat as can be, and so will the second set be. The only difference between them is the supplied colour profile from PhaseOne. The colour rendition between them is noticeably different on screen, so I expect there is a difference. However, I don't think either will score well on dynamic range.
I will do yet another series with manual adjustments, to compliment the automatically adjusted.
Jostein

don't replace the files yet. the first TIFF file is causing a crash in IMATEST and i need to have Norman look at it to see if there is something he can do. i've processed some of the others and will be done in about 15 minutes, but the results aren't good. your first set of conversion settings alter the color considerably and also lose the white patch. it has too little contrast compared to the next darker gray patch. the black is also nowhere near black. highly compressed dynamic range means more noise and less accurate color.

doh.
I sent a followup some hours ago, but it didn't make it back to me, so here goes again.
