Digital BW, The Print

Are you on Dan's Color Theory List?  If not, I will try to find the challenge (it was according to Dan mis-paraphrased at some point so I want to find it in accurate form) and will send it off-list.

As to the argument that you lose tonal values, his response is that theoretically you do but in the real world the result is identical.  I am not an expert so I will not take sides one way or the other.

| Hi Maris,
| 
| I would like to see Margulis's challenge, because for tonal adjustments you
| MUST MUST MUST do them with high-bit data, or you lose tonal values, period.
| That isn't arguable at all.  And it DOES matter when doing B&W, especially
| with Piezo, less so for color, but it still matters.
| 
| What I have found, is sometimes the purported expert isn't saying what you
| think he's saying...problem with this "field" is not only the misuse of
| terminology, but the reference one is talking from.
