Welcome to BTZS.org

These forums are provided as a service for the photographers in the BTZS
community but other photographers who are seriously interested in black-and-white,
large-format photography are welcome to participate.
BTZS refers
to “Beyond The Zone System,” the title of a book I wrote almost 25 years
ago, and is now in its 4th edition. This was not an attempt to discredit
Ansel’s work; I believe his Zone System concept was innovative and ingenious,
and his art and technique have inspired generations of photographers. But
times have changed and we now have tools and materials that were unavailable
when the Zone System was born.
As a result, BTZS is “beyond” the
Zone System in several ways. First, we test our materials using sensitometric
methods to produce test data that are more comprehensive and more reliable
than conventional empirical methods can achieve. Second, we use sophisticated
computer programs to analyze the test data in the lab, and generate working
data in the field. Third, we replace “N-numbers” as indicators of development
extent with Average Gradient values which are more specific and more reliable.
Finally, we recognize that both science and art are essential elements in
photography. BTZS can equip you with the knowledge and skill you’ll need
to handle your materials effectively, but that’s as far as it can go; it’s
up to the artist in you to apply what you’ve learned to produce images that
are worth looking at.

Phil Davis (1921- 2007)
Phil Davis
died at his home in Webster Township on July 2, 2007. He was
born in Spokane, WA on October 15, 1921, the son of William B. and
Mary Augusta (Maples) Davis. The family moved to upstate New
York when he was twelve and after his graduation from high school,
he enlisted in the Army Air Force. He was commissioned in 1943
and served as a flight instructor until his discharge as a First
Lieutenant in 1945. He graduated from Albright Art School in
Buffalo, NY in 1948 and joined the staff of the University of
Michigan's College of Architecture and Design as an instructor
in design and drawing. From 1964 until his retirement, he served
as a Professor of Art in the University's School of Art, teaching
photography and drawing.
He received two Horace H. Rackham
Foundation Grants, in 1967 for investigation of historic photographic
processes and in 1974 for further investigation of non-silver
processes. During those years, he also worked as a freelance
photographer in advertising illustration and received numerous
awards, medals and honorable mentions from the Detroit Art Directors'
Club and from similar organizations in New York and Chicago.
As part of the University's Sesquicentennial celebration in
1967, Phil conceived, produced and supervised installation of
an exhibition of 264 photographs mounted on steel structures
on the Rackham Mall between Hill Auditorium and the Michigan
League. A book of these photographs titled "The University" was
published by the University of Michigan Press. His other publications
included three textbooks, many magazine articles, a limited edition
of platinum prints made from noted cinematographer Karl Struss's
original glass negatives, and "The Dexter Portfolio", a limited
edition of mounted black and white prints. His work is represented
in numerous public and private collections, including those of
the Detroit Art Institute, Chicago Art Institute, International
Museum of Photography in Rochester, NY and the Museum of Modern
Art in New York City.
In addition to appearances as guest
artist, juror and speaker at various events, Phil conducted a
series of workshops throughout the country in his "Beyond the
Zone System" method of producing photographs using proven scientific
testing methods which allow photographers to produce superior
photographs through a precise, working knowledge of their chosen
materials.
Phil retired as Professor Emeritus of Art in 1985
and in 1988 one of his former students, Chicago architectural
photographer Nick Merrick, organized and curated "Phil Davis,
Photographer: The Teacher and His Students", an exhibit in the
Paul Slusser Gallery of Phil's work and that of 20 of his students.
He is survived by his wife Martha (DeLano), his sons Carl (Becky)
of Eaton Rapids MI and their children Anna-Lisette, Charlotte,
Gretchen, Philip and Lucy; Tim (Katy Robinson) of Byron Center
MI; and Jon (Amy Mattox) of Norcross GA; his sister Helen Beck
Reimondo, her sons Tom and Dave Beck and their families. In accordance
with his wishes, cremation has taken place and there will be
no services. Memorial contributions may be made to Hospice of
Michigan or the Dexter District Library, 8040 Fourth Street,
Dexter MI 48130.
