So I've seen it here at APUG but for the life of me I can't find it.
Anybody know where to find it?
Do you mean like the tone reproduction curve that Steve Beskin has posted but with Zones instead of log values?
Good thought but no.
It was a Kodak chart as I remember.
If it is this you are looking for, it can be hard to find: http://wwwtr.kodak.com/global/en/pr...wFilmProcessing/selecting.jhtml?pq-path=14053
I've bookmarked it.
It can be found by searching for Kodak Selecting a Film Developer.
You're probably looking for the funnel... Sure it's in one of those threads...
Right at the top of this thread... Hiding in Plain Sight...
Thanks but not the one.
Bingo! Thanks Bill.
Just for reference, this representation of tone reproduction is called a Dorst diagram (proposed by Dorst in the 40s). It was proposed as an alternative to the "windmill"/quadrants representation which is from Jones.
Interestingly, re-reading the short section on this in Henry, apparently the original Jones study included windmill diagrams with up to 10 transitions, which must have been quite complicated to follow. Perhaps this is one of the reasons for Dorst's proposal, which although less "graphical", seems easier to follow when more than a few transitions are involved.
Like this very low resolution example.
Exactly. Even a high resolution version would be clear as mud.
Thanks for the info Michael.
I do find it easy to follow in comparison to windmill diagrams.
And Stephen that is quite a chart!
