Peter,

Your entire post has absolutely nothing to do with filmscanners.  It is
simply your belief and critique about me, and appears to be an attempt to
throw dispersion on my credibility.  If you want to comment on me
personally, as opposed to something technical, I believe you should keep it
OFF LIST, or not say it at all.

And how do you know I'm "rapidly losing respect of the group", Peter, do you
speak for "the group", or am I right, you are simply doing this, since you
can't argue technically on the subject, to throw dispersion on my
credibility?  What makes you so arrogant that you can take on the voice of
everyone else?

It's my field of expertise, and I've been doing it for 25+ years, and with
no one in my field ever questioning my understanding of it.  Have YOU ever
actually use dynamic range professionally, as in, while working with other
people who know this stuff inside and out?

I am merely correcting what is a very prolific misunderstanding, that you,
and others, seem hell bent on adding to.

There was PLENTY of foundation given, as well as corroboration...as in from
the ISO to name the latest one...but since it all goes against YOUR
understanding, you don't want to consider it foundation.

It is only YOUR belief (and probably Julian's) that I'm "in the minority".
I have FAR more people supporting that I am correct, than you and Julian
disagreeing with me.  I HAVE verified my understanding with many other very
prominent people throughout the past 25 years, and they agree with my
understanding.  I don't need to go RE verify this.

I've posted MANY examples, as well as CLEAR definitions.  Everything is out
on the table.  No one has spotted any "error in [my] reasoning".

Professional route for what?  I do this for a living, Peter.  I AM taking
the "professional route" EVERY DAY, and have been for 25 years.  This
certainly appears as simply your way of trying to case unwarranted
dispersion on my credibility simply because you can no longer argue this on
any technical merit.

Sigh.  The term "dynamic range" has been around for a while.  There is no
"new information" that will re-define it.  It is what it has been for many
years.

I was unaware of the ISO spec at first, and once I read it, said that
certain assumptions had to be made for it to be right.  I read it very
carefully and figured out what those assumptions were, and they are correct
in the context, which given that, made the ISO proposal entirely correct.

Sigh...again.  Read the ISO spec.  Try to understand what it says and go
back and try to see how it matches exactly what I've been saying.  All the
information you need is in front of you, if you choose to look at it.  And,
please stop your little game of trying to case dispersion on my credibility.
It is unwarranted, and is simply cheap.
