This post will be examining camera film. Not as
riveting, that I know, but this is still an interesting object in terms of its
history, name sake and how it works. This is the unboxed Kodak 200 Color Plus
Film that was also a sponsor of the Olympics!
The
Kodak company’s history goes back to 1880, when George Eastman found a way to
successfully commercialise dry plates in the US. A year later he teamed up with
Henry Strong to form the Eastman Dry Plate Company. (Kodak)
George
Eastman then went on to work on a way to cover paper in the photographic
emulsion to expose photographic positives. With William Walker, Eastman,
developed the Eastman’s photo plates. (Clay 2020)
These
plates where known as dry photo plates, which were an improvement on the wet
photo plates (a lot of imagination went into naming these plates). The easiest
explanation between the difference comes from the ACS:
“Back
in 1878, the 24-year-old Eastman was planning to use the “wet collodion” process
to take photos on his Caribbean trip.”
(Where
according to Kodakery (2012): “chemicals spilled and ruined his packed clothes
during a trip to Mackinac Island in Lake Huron…”)
“Eastman
would later recall that this technique entailed “taking a very clean glass
plate and coating it with a thin solution of egg white. This was to make the
subsequent emulsion stick. Then we coated the plate with a solution of
guncotton and alcohol mixed with bromide salts. When the emulsion was set, but
still moist, the plate was dipped into a solution of nitrate of silver, the
sensitizing agent. That had to be done in the dark. The plate, wet and shielded
from the light, was put in the camera. Now you took your picture.” It was a
messy, time-consuming process.
"As a
better alternative, Eastman soon switched to the dry plate emulsion process. In
this technique, glass plates were coated with a gelatin emulsion of silver
bromide and then dried. This formed stable plates that could be produced in
advance and stored, instead of having to be prepared right before exposure.
They also had another advantage over wet collodion plates: They didn’t have to
be developed right after a picture was taken. Eastman adopted the improvements
of British photographer Charles Bennett, increasing the sensitivity of the
photographic plates, which shortened exposure times.”
This
gelatine emulsion was perfected, which lead to Eastman adding film to the
product lines. These films were a gelatine-chemical mixture on paper rolls.
These rolls had special holders (also invented by Eastman) to still be used on
existing plate cameras. These rolls also won Eastman an international prise
because of its lightweight in cameras and speed in taking pictures. (Acronis
2024)
The
name Kodak was trademarked in 1888, when Eastman released a camera, that had
paper film in it and could take up to a hundred photos. (Clay 2020)

Then
in 1935, Kodak released Kodachrome. This was the first commercially successful
colour film and came in the 35mm slides. Then in 1942 came Kodacolor, “the
world's first true color negative film for still photography…” (Kodak)
This
was then proceeded by Kodacolor II in 1972, then came Kodacolor VR100 in 1983,
which was based off of Kodak Disc films, that had higher speeds of agitation
and meant that the emulsion doubled in speed. This lead to the ISO going from
100 to 200. (Visual Korner 2024)
This is a simplified version of the history of
the Kodak colour film. So, here is a table giving a timeline in more detail: |

All
this leads to the Kodak Color Plus film that came out in the early 2000s and
used the trade mark colours of red and yellow, which: “immediately brings to
mind punchy contrast and vivid tones.” (Saade 2021).
Kodak
200 Color Plus Film has a lot of good reviews. One of these being from McAdam
(2021), who praises the film’s vintage look that comes from its warm tones and
the noticeable grain. He points out that it performs its best in sunny warm
conditions, where both saturations and contrast increases. In clouded, overcast
or in spaces with cool colours, the film, can lose this vintage look and gives
it a more “real” look. Which isn’t a bad thing, because there is still depth to
the pictures and gives the pictures a calmer and life like feel.
Others,
like Panorama Circle (2018), points out that this film, although not really
advertised by Kodak as much, has become the inside knowledge for photographers.
This is because it is an all-purpose budget friendly film, that can be used
outside or in a studio, for portraits or landscapes. It has basically become
the tool that every photographer should have when taking pictures with a film
camera.
Shu
(2021), shares these same sentiments, by pointing out that it is as good as the
Kodak Porta 400, but cheaper. Can handle both overexposure and under exposure
and has a great colour rendition, which makes it ideal for any situation.
But
Shu (2021) also explores the cons of this film. These are:
“It’s
a 200-speed film so it’s not as flexible to use as a 400-speed film like Kodak
Ultramax 400. The slower speed of the film isn’t as easy to use in low light or
on cloudy days. The warm color tones of the film stock might not fit with
everyone’s style.”
Now for the specs of this film. This particular
Kodak 200 Color Plus film has an ISO of 200 (hey this number is also in the
name, I wonder if it is connected?), an exposure of 24 and this means
(according to McKay 2024 and Lomography 2024) that it can take up to 24
pictures. Is ideal for outside shots, both sunny and cloudy conditions. Is a
35mm film, a dB of 135 and uses the developing process known as C-41.

The
exact date of this film is between two options. Option one is a broad
estimation, this option is that it is somewhere between 2003 and 2008. The
evidence for this is that the copyright date is 2003 and that there is an Olympics sponsorship on the box, which according to Museums Victoria
Collections (2024), Kodak has been involved with the Olympics since 1896 and
became “the first of 'The Olympic Program' sponsors in 1986.” But this all
ended in 2008, when Kodak ended its partnership after the Beijing Games. (SBJ
2007).
The
second option is more precise, but could be wrong and that is that this film
came out in 2007(/02). This comes from the fact that the expiring date for the
film is 2009/02 and according to Bryan-Smith (2024), film’s expiry date is
usually two years after it was manufactured.
But
this doesn’t mean the film can’t be used. Because even though as Bryan-Smith (2024) writes: “Over time the chemicals on the film lose their potency and start to
deteriorate. The silver halides in the films’ emulsion degrade and lose their
sensitivity. As a result, colors will lose their vibrancy, and contrasts will
fade and grain increases. Eventually, expired film becomes foggy and unusable...”
It
all comes down to how it was stored and that if you plan on using the expired
film the general rule is that you overexpose the film by 1 stop for every ten
years after the expiry date. (Lomography 2024)
Now
for an explanation on how film captures those memorable moments. The first
thing is that when you press the shutter, light, from the camera’s field of
view enters the camera and activates a chemical change on the film. (Woodworth
2024)
This
film has a transparent base that is made of cellulose triacetate, acetate, or
polyester. This is also where the emulsion is and protected. This emulsion is
made out of many layers that has dyed silver halides. This is what reacts with
the light to form the image that the camera captures and each layer captures
the wavelength of each colour spectrum in front of the camera. (Lomography
2024)

It
should also be noted that these silver halides are in crystal from and
suspended in a gelatine solution. (OPS 2020)
This
chemical reaction between the light and emulsion is due to light’s energy being
distributed through photons. It is these photons that reacts to the film. As
Woodworth (2024) writes:
“It
is the energy in each photon of light that causes a chemical change to the
photographic detectors that are coated on the film. The process whereby
electromagnetic energy causes chemical changes to matter is known
as photochemistry.”
This
takes place at the back of the film where the layers are held as well as
spectral sensitisers, that help with colour. There are also other chemicals
that “are added internally to the grain during its growth process, or on the
surface of the grain. These chemicals affect the light sensitivity of the
grain, also known as its photographic speed (ISO)” (Woodworth 2024).

This
was a long one, but still interesting. I did not expect so much for a small box
of expired film. I hope this was fun and thank you for making it to the end.
