Norbert E. Ligterink's manuscripts not on the archive
Some of my work did not end up on any archive for several reasons.
I wrote a little article accompanying a talk I gave for the
Society of Archive Conservators (VAR) at the City Archive in Amsterdam.
It deals with water in paper and physical aspects of conservation.
A more technical note I wrote more for myself, which I think deals with
a very nice model to describe water in paper.

In my thesis there are three chapters that never made any other
publication. Chapter 2 deals with PDE's on the lightfront. Chapter
4 deals with a differential approach to dimensional regularization,
and chapter 6 deals with Fock states aspects of bound states. Strangely,
I like these chapters the most; it goes to say that original work
never pays.

During my film class in 2002 I came across depth-of-field tables,
which are a pain in the neck. I worked out an easy way of doing
all the calculations on the fly (in my head). The details I wrote
in a little note.

I have had an interest in computer graphics, compression, and
(objective) colour theory for a long time. For a possible project at ICN
(Institute Collection Nederland) I wrote an overview of aspects
for the documentation of paintings and graphical works.
