Zone 1 density

I tend to look at the gradient of the curve. If there is a positive slope, there's density difference. Of course how well the difference is perceived in the print has to do with a number of factors including the amount of viewing light.

In regard to the definition of the paper's 90% D-Max, I only have the 1983 version of the standard, but it does reference Jones' Control of Photographic Printing: Improvements in Terminology and Further Analysis of Results, which I do have, but not as a pdf. Maybe I'll scan it, but like most of Jones' papers, it's long.

I have get my own zone I density by printing my test negatives to the VC grade 2 (using my enlargers VC head). For Pyrocat-HD developed films the density FBF+0.12 is barely distinguishable from paper's full black, but it's hard to see if you don't know that it should be there.
FBF+0.17 is the point where I can see the zone I as clearly separate value from paper's darkest black.

These works ofcourse only with tested paper and staining developer. However the trend seems to be quite same with all material I have tested.

Generally I agree with WBTM book's FBF+0.17 as speedpoint as it seems to work good with my eyes under normal lightning situations.
The Adam's 0.08 - 0.11 values are a bit too low leading zone I being practically same as zone 0.

One's way to exposure and transfer visualization to the negative causes also variating to zone I density. I place often dark shadows to II and some of darkest to zone I without thinking that zone I should be treaded as pure black. Perhaps the way I use ZS is one reason why I prefer bit more dense zone I value.
 
 
 
CPorter in your Abandoned House #3, is it the top right side of the window you measured for zone II?

Thanks
 
Well, to me, pictorial value is a conceptual and artistic term. Something of pictorial value is anything within the picture that affects the picture. So, everything present in a picture has pictorial value by definition. Everything in a picture does something for the picture (and even things outside of the picture do so, such as all the details of how it is presented and viewed). That is just common sense. Instead of stating that something used in a picture has no pictorial value, why not simply explain what something's pictorial value is?

I also rarely place anything below II, and I am not saying that this is common practice. As I have stated a few times in this thread, I am most concerned with obtaining placement accuracy and expected tonal relationships with II – VIII. Subjects that end up a little out of place tonally at 0, I, IX, or X are not a great concern of mine. Printing can take care of any slop there. But printing cannot add the subtle bits of detail or tone that are lost in the sagging "toe" of a film's curve if one calibrates using zone I. This is why I don't think using zone I for finding an EI is the most useful way to go about it.

Actually, I placed the shadow beneath the house on Zone II.

I’m sorry, but I find any discussion on exposure using Zones problematic. They're great for helping to conceptualize exposure, but Zones are basically arbitrary and don’t intrinsically represent actual exposure values. It’s not like saying an exposure of 0.0085mcs for a 100 speed film and showing where it falls on the film curve. Zone II for someone under rating their film one stop is different than Zone II for someone rating it at the film speed and the they will experience different results.

Using Zones with exposure also tends to imply some specific exposure/density relationship that doesn’t exist. And even if you don’t agree with that statement, isn’t there an inherent contradiction when talking about placing a value at a specific Zone and then talking about adjusting the EI, or talking about placing a value on a different Zone to actually mean adjusting the exposure index, ie “I shifted my Zone II placement to Zone III”? Exposure is about placing the subject luminance range on a usable section of the film curve using a single value of luminance in the determination of exposure that represents the multiplicity of values of the subject.

In discussions, there’s also a tendency to mix up the concepts of exposure Zones with print Zones. If I under rate my film one stop, I’m going to have separation in the negative at Zone O, but there won’t be separation at the print’s Zone O. So, which version is a person referring to when they say Zone O?

That’s the problem, without an explicit expression of parameters and actual values, people can be discussing very different scenarios without realizing it. The discussion then becomes no more useful or conclusive than arguing about how many angels can dance on the head of a pin.
 
Zones as I usually discuss them are print values, not negative values. I think we all know that, though perhaps all the shorthand used in Internet discussion in order to keep wording brief and clear makes it seem as if we are saying that zones are equivalent to negative exposures. What we are discussing is the minimum amounts of negative density necessary to get traces of detail or texture to appear on the print right at the print zone where they first become visible, when a normal print is made. In other words, calibrating film curves to land in a certain way atop paper curves so that we have the thing we call the "nomal print, " and craft negatives to match it. It is not necessary. It just makes printing easier and more streamlined, and problems easier to judge. Of course one can print any amount of density down to whatever print zone one wants, especially with the new films that are hard to overexpose to death.

Yes, by your definition. My definition of pictorial value is different, and that why we have a different opinion about Zone I being of pictorial value.
 
Fred Picker's instructions use the print in determining Zone placement. He advised to carry small prints of eight zones as a field reference.

Why don't you just tell us what it is then? Quit acting like everyone should inherently know your definition for some term.
 
You do realize that this was not AA's definition of Zones?

Yes, I do. But I don't feel like writing out "the placement of a tone relative to middle grey via exposure so that it correlates with a certain print value once calibration of ones process has been acheived." I say zone when discussing placements that result in certain print values. My point was that I do not use zones to discuss negative densities directly.

Who is 'us' and 'everyone'? I think it's just you at the moment. Anyway, I already did (post#32), but it's not even important for this discussion. What's important is that there are different definition for pictorial value, and the people having different definitions will never be able to agree if Zone I is part of it or not.

As I said, whatever works for you is fine with me.

For what it's worth, Ansel Adams avoided the term altogether and differentiated between textural and dynamic range. For me, the pictorial range is in-between the two, going up to, what Phil Davis called, the 'last usable print density', IDmin or 90% of Dmax.
 

Post number 32 does not contain a definition of pictorial value. It contains your statement about certain zones not having any because they lack texture. They lack texture, therefore IMO they have no pictorial value is not a definition; it is a line of reasoning. Flip it around and it is a definition, and a very incorrect one, I would argue. I think you have your words crossed. Since when does pictorial mean textural? The phrase "no pictorial value" sounds incredibly arrogant and awkward. I think pictorial is the wrong word, as it is so broad. Look it up. Cannot you just say no textural value?

I also seem to remember at least one other poster disagreeing that certain zones do not have any.

Correct, but that 'one other poster' already agreed that the Zone System is flexible enough to adjust it to one's liking and workflow. I'm petty sure, the inventors of the Zone System would've agreed with that.

Asking for my definition and then arguing that my definition is not a definition, per your definition of a definition has to be, is just taking things too far.

All the best.
 
Unbelievable! Just come out and say what you mean so that I, a mere peon, can try to understand! Pretty please?

The problem is that your definitions stinks, and you do not want to spell it out plainly because it is wrong. You'd rather tuck it awkwardly into something you wrote a few pages back, and then arrogantly act like I am crazy and stupid and below you for not agreeing.

So, Ralph is right and the ignorant peon is wrong, as usual. Unbelievable. If you have an argument to make, then make it. Quit playing games to dance away from the fact that you are wrong.
