New Silver Chloride Azo type paper

[Kirk Keyes]

This is here in apug just running with "3-dimensional look" in paper. I am impressed about the lyric textes and the descriptions about the feelings. I prefer, what I can measure.

Me too - that's why I started that thread.

Well, engineers and figures...
I must admit though that sometimes I use figures too. But actually they all are of limited use. They can yield a means to compare films, papers etc. But the final standard would be man; who is known not be standard.
Thus next to granularity there will still be a term like graininess…

Concerning paper there are more features to name: weight, curl, haptic, smell…

Haptic?

PE

Haptic?

PE

Haptic, from the Greek (Haphe), means pertaining to the sense of touch.

Malaprop ???

 

[Photo Engineer]

Thats Greek to me. I might have used tactile or some such. IDK.

PE

 

[AgX]

Yes.

In German we (or rather designers) use `Haptik´, a noun, for the manner something feels like.
Of course it is one of these modern words, but otherwise I would have to use phrases as `the property to provoke tactile sensations´.

After posting I was not quite sure whether it is used in English too, but I was too lazy to check and to correct in case neccessary...

By the way, I got the impression that `tactile´ was used here in many threads in a weird way.

Anyway, to me `tactile´ is more related to the sensations someone gets than with the property an object hast got to arouse such sensations.

Digital?

Once I have seen the diagrams. This gamma distribution seems to be a quantum effect via sensitizer or dyes, depending on this, it can be minimized, when pictorial necessary, or enhance. Any minimal discontinuity (like low contrast resolution parts - the grain from a photographic wedge scale) interrupt this quantum effect.

When you look at the uneven development of negatives, special looking at the borders near the perforation:

1. Not enough movement is only a part of the truth
2. an equal great part (maximal the whole 24x36mm negative) has boarders with higher densities thanks the quantum-effect, when it is not chemically cancelled.

A friend told me today: When you enhance the quality of a paper (and you use not modern high resolution films with minimized grain), the (low contrast) grain becomes more visible. Enlargements from normal mix-emulsion grained 6x6 negatives to 8x10inch paper will -on thuch paper- suddenly looks more grainy. This happens in around ? 1984-88 ? with Kodak Polycontrast 3 from this production date. Later produced paper with that name had showned normal qualities.

Well, I've been away for a bit, came back to see what's up with APUG, read this post (all six pages) kind of expecting to see something about obtaining a silver chloride paper, at least something about silver chloride coating recipe, but didn't see anything of the sort. Am I missing something with this post? Sorry if I am, just wondering if I've gone brain soft during my absence.
