Luc Barthélémy doing some animation (mid 80's)
In France, Mr. Luc Barthélémy is working on his own 65mm film scanner/recorder. He has been a film fan since the 1970s and he is especially fond of large format 70mm film. He has his own
DP70 and and the past few years he has bought some large format equipment on e-Bay, which he is putting together for a private project. I'm delighted that Luc Barthélémy has accepted my invitation to tell a little bit about himself and share his project ideas with other
in70mm.com readers. editor
My name is Luc. I'm French and I live at 30 Km from Paris
(south). I was born in 1968. In 1976, my father worked as a
projectionist in a cinema near Montparnasse. There, I was bitten by «cinema». My mother brought us, my brother and I, every Wednesday. So we
could see the films my father projected. I had the chance to see every
film released during this year ("The Enforcer" with Clint Eastwood,
"King Kong" with Jeff Bridges, and so much others).
There were four screens
and four 35mm projectors. The chief projectionist left one day. And
several months later, during year 1977, he told my father to come see
him at his new cinema: Le Broadway.
He was projecting "2001:A SPACE
ODYSSEY" for its 1977 re-release. I can say that I saw 2001 when I was 9
and that was the big trauma for me ! It was absolutely astounding. This
screen was known as SPACIOVISION, one of the biggest 70mm screen at the
time, or something like that. After the projection, we went in the
projection booth to see my father's friend reloading the two enormous
DP70s (I was a child and they were giants). Since then, I only wanted to
do films, with 70mm and "2001" in mind.

65mm 5-perf camera on the Solitaire 8XP film recorder
Because I loved to draw, I started to make small animation films (my
parents helped me to buy a Super 8 camera). I really started to film
cartoons around 10 years' old. So I continued during my youth to do small
films. I experimented animation, animated models, SFX, explosions, etc.
They were not really films but some kind of tests or demo reels that I
loved project to me and my brother.
Then I jumped to 16mm. I did a lot
of small films again. At that time, there were plenty of S8 and 16mm Kodachrome
everywhere. It wasn't too expensive. And it was my hobby. It
was great time.
During the 80s, I was looking for theaters showing 70mm
film and these years brought us some 70mm movies or blowups: "TRON",
"GHOSTBUSTERS", "DUNE", "2010", "BLADE RUNNER".

Complete shooting unit
During the 90s, I spent a lot of time at the
Max Linder Panorama theater. In August, they usually did special 70mm screenings: one or
two films a day, during all the month. There, I saw "TRON", "BRAINSTORM",
"2001", "2010". The last film I saw there was "BARAKA".
Being an adult, I
started to work as a software engineer in 1991, not in the field of
cinema. But I was interested in 3D, computing, imaging, electronics,
etc. So I never stopped to work all these subjects, for my own. During
these years I also had the opportunity to find some beautiful pieces of
machinery: projectors (two FP20, one DP70), cameras (Cineflex 35mm),
film recorders (Agfa-Matrix, Solitaire 8XP), etc.

The 65mm project

The 5-perf movement
The last five years enabled me to setup the project I was dreaming of. By
acquiring a 65mm optical printer camera (on eBay!) and having found an «old» MGI's Solitaire film recorder, I told myself it would be great to make
a 65mm shooting unit.
I wanted to recreate for fun a short sequence of the "TRON" movie. I remembered the fascination I had for the computer graphic
imagery of this film especially the lightcycles, the tanks, etc.
The look was
very particular, and really away from the CGI we can see every-day now. And
because there is no available software to accurately recreate these
pictures, I started to write my own software, taking care to closely match
the "TRON"'s look. I am still working on it.

Camera and magazine's motors
For the film recorder, I spent many hours to design, adapt and test every
parts. It is really a big task. Some years ago, and before I could imagine
and had the possibility to setup this project, I contacted
the famous lab in
Paris that make 70mm films, just to tell Mr Failliot how I admire the work
they do and how a pure fan I am.
They were so kind that Mr Failliot showed
me the lab, and some months later, Mr Benichetti (Dominique, as he asked me
to call him) constructed some missing parts of my 65mm camera.

Shooting software
I had to drive the camera by my own electronics and software instead using
the module (black box under the camera) capabilities. The module drives the
filter color wheel inside it, my software drives the motor through a custom
circuit (not shown on this picture), by the PC's printer port.

8XP's CRT during exposure
Pictures appears sharp and centered in the 65mm gate (here loaded with
blue leader). During my tests, I use a thin piece of tracing-paper 53mm wide
in the gate, instead of costly optical measurement instruments.
The manufacturer of the film recorder (Management Graphic Inc.) doesn't
exist anymore. No documents freely exist.

Front panel during exposure
Everythings seems to be «TOP SECRET». Of course it is, because of highly
technical content and patents. And maybe, because a lot of the technology
used in these old film recorders are, more or less, the same used in
state-of-the-art film recorders.
The film recorder properly receive the pictures, here during exposure. The
exposing time is long: around nine seconds per monochromatic pass. An RGB
picture is exposed in around 30 seconds. Add one second for the film
advance. I am currently working on exposure time to reduce it.
The software works very well. I use pictures of 4096 x 1854 and 8192 x 3708
pixels for my tests. This film recorder can expose from 2048 x 2048 up to
8192 x 8192 pixels. Each pixel use 12 bits of data for each color channel
(4096 gray scale values). The color wheel is equipped with red, green, blue
and neutral filter. So, black and white pictures can be exposed. This
provides chromatic separation recording capabilities.

TRON's like test background
My project is not, at first, intended for commercial purposes because it is
a very personal project. I think that people (professionals) wanting such
services use state-of-the-art technology. They wouldn't trust the «guy
fixing its equipment in his garage», even if lot of adventures have begun
in a garage. This being said, it could be a good occasion to see 4K or 8K
pictures shot on 65mm for 70mm prints.
I am not a professional in the field of cinema. Just a simple «amateur».
I wish I could work in this field but it never happened. The only way for me
is to do it by myself. With my own money (very few) and on my own time (very
much).
