My thanks to you for landing on this blog and staying long enough to
read the material. This is the first post of this new blog, as I have
put much time and effort over the past five years blogging on writing,
and digital publishing. That's the dicey part of having more than one
interest in life. There are times, however, when said interests are
combined to satisfy both mediums. I have written on black and white film
photography, focusing on the black and white negative, and the basics
of photo chemistry that controls most aspects to the outcome of negative
development.
It is not the case I blog because I have way too much time on my hands,
even being in the retirement mode. I come up with the time to blog
because doing so has been beneficial to those who come after me, as
independent writers, or black and white photographers learning their
craft. If you want to read about writing in general and independent
publishing using print on demand platform services, that's the other
blog; www.brothercoyotepublications.com It
is there you will find the books I have published under my Brother
Coyote Publications brand, and the most recent book on black and white
photography.
Thirty years ago, photography was all done on film, and chemical
developing out methods were used on the negatives and subsequent silver
gelatin prints, both in color and in black and white. I worked
exclusively in black and white, specializing in that medium, when no one
else did, or would. There was a really good reason why I chose this
historical path. Truth is, I'm all but color blind in Red and Green. I
would not be the go to person to print your color negatives. Having one
eye, well, that's another story. I see panchromatic tonalities just
fine, and understand how those tonal ranges are related to negative
densities, and what that has to do with successfully printing
photographic images using historical processes. Not same same printing
silver gelatin images using projected enlargement. Hand coated printing
processes are way better. But that's just me.
I still have a portfolio of salted silver prints in the 5"x7" format
they were shot, from those thirty years ago, as well as a half dozen gum
prints left over from that time. I learned even from looking over those
prints of long ago. I attribute that to the ensuing years of learning,
offering the larger perspective on things, from hindsight. Having very
recently come across access to a darkroom facility, my deeper urges to
print once again has become unruly enough that I am now printing in two
mediums, teaching the nice gentleman who operates the darkroom the
processes. We began with the gum dichromate process. Although it is
still referred to as the gum bichromate process, it is but historical
tradition that continues this practice. The bichromate has long since
been replaced with the more sensitive dichromate version, before I was
born even, and I'm a great grandfather.
It will be this gum process I will begin with. Printing has begun with
my new darkroom friend. I showed him how to build a simple printing
frame for gum printing, that allows for correct registration of the
print, which is one of the two primary demands of this medium. The other
demand being correct contract index & density range of the
negative. My friend learned a lot about the density range of the
negative on his first test print. Not nearly enough. My first test print
will not be an exhibition print because of its flaws. What was to be
determined for me was how far the density range can be taken to overcome
the inherent drawbacks to gum printing; texture and detail. Gum prints
have historically tended to be dark and sort of muddy, with sometimes
swirls of color. The primary reason for flat gum prints is flat
negatives. Back in the day, I had to rely upon paper negatives for my
enlarged gum prints, and that has a limited tonal range. Now, I have the
advantage of digital printers printing the negatives, to size and with
the aid of Lightroom 4 to enhance and dictate the negative curve. The
outcome is nothing short of amazing, in comparison to paper negative
gums.
Much can be said about preference and process, and will likely all be
said, but for now I just wanted to begin the blog and say hello. I'm
posting the first test print of the gum "The Flute Player". The flaws
are visually obvious, with the micro-cracking in the darker tonal range.
It was the boundary to just how thick one can mix the gum arabic before
it begins to crack in a print. This is important. There is a handshake
between the thickness of the gum mixture and the paper sizing. This is
to keep the watercolors, suspended in the gum arabic solution, from
direct contact with the paper, thereby staining the paper and ending
that print. I will be posting the basic procedure and mixing percentages
later. For now, here's what a gum looks like with my idea of a negative
with the correct contrast index for a gum print.
