Ernst, I may change my mind - and I do plan to put the next 2-3 months into glossy formulations to try and see if I can't dig up something that feels like new ground to me. I am definitely in an ink formulation mood and very excited about working in this direction for an extended period. But right now, the only thing I am liking about my process is the extension of tones in the shadow areas - it's very illuminous - and on some papers is moving into the warmer associations of selenium, and I believe it is a direct result of extending the dMax, but not the dMax itself. Hope that makes sense. And yes, as its been better stated here already - we really do need a certain amount of light to reflect off of black to actually see "black". I just do not want to make prints that seem to be shouting BLACKKKKK!!!! I prefer the subtle bits just up to that ear-splitting scream and I am blessed with the ability to linearize that as well as curve it up or down within my linearization process. It seems like a richer area with the extension of dMax. The obviousness is that the space between the points is now lengthier. With matte Piezography profiles I can separate 256 gray levels easily, but the shadow points though open, are a little difficult to discern. With the glossy/dMax profiles, its like prying every thing open in these shadows - so the dMax becomes the enabler. On the other hand, I went to the Dallas Museum of Art today to look at the exhibition of Piezography prints that John Dean printed from the original Harry Burton glass plates when Howard Carter and Lord Carnarvon discovered the tomb of Tutankhamun. These plates were apparently taken before the artifacts were removed and some immediately after they were removed. I saw masterful printing and extraordinarily beautiful prints. These are made with PiezoTone CarbonSepia inks and the blacks are totally appropriate for the work. dMax does not enter into it. Dean's control of the process is gorgeous. So the image quality really is about craftsmanship married to the intent of the photographer. The absence of reflection on the print surface allowed us to see them without any visual interference whatsoever. The original plates are (I assume) appropriately exposed, but the printing in any event, and the control by Dean, created extraordinary image quality. I believe in this case, glossy dMax would have been distracting. And dMax without the gloss would not have added a thing. These prints were lit at about 50 - 75 lux. The blacks were perfect. So, when is gloss and its associated dMax appropriate? And if we define that criteria, are we penning it in in some sort of genre? Why does matte work always get away with "everything"? Is it the spoiled child? lol Jon --- In DigitalBlackandWhiteThePrint@yahoogroups.com, Ernst Dinkla <edinkla@...> wrote: > > Jon Cone schreef: > > Just my opinion, but the high dMax prints have not really done that much for me visually.

The monster black does not take on all the "meaning" - rather the depth of the darkness before it is what I find very visually compelling. To me it's like giving steroids to Piezography. The dMax is not an "accessory" to call attention to the outfit. > > > > dMax for dMax sake is a vestige of silver print (IMHO). Silver gets very black and photographers like "very black".

I think as we move the medium further that the bar should also be raised. I don't think it's enough to say one is almost as good as silver print, or as good as silver print... I prefer to try and make processes that become their own level, and that necessarily means adding something that is not familiar. And also, may not be everyone's cup of tea. > > > > I do not know that others will agree with my opinion on dMax, until they see open linearization just up to dMax. Most of the digital b&w glossy that I see is very closed shadow. I also do not know what will be gained by going deeper. I just know that I have not yet come up against the point at which I can not get it "blacker". I think it will only make the dynamic range more expansive - rather than punchier. If I were to release this system in some way that could be used on Epsons, I would have no doubt that most users would prefer to force more of the 3/4 range into blackness and go for the "punch". To me that reduces "image quality", but might enhance the "wow" factor for the photographer. > > > > SO my question to you Ernst, is "What is image quality?" > > > > best, > > > > Jon > > Jon, > > That subject line had to be short.
