..Chances
are every negative on a roll of film is not always
going to be perfect. As a matter of fact, probably
only 3 or 4 images on a roll of 24 will be worthy of
being printed onto a piece of expensive light
sensitive paper.
..Professional
photographers and students will often take an
alternative approach, than just printing every single
frame on a roll of film. They will make a contact
sheet a selectively choose the image they like best.
..All
papers are light that are light sensitive, are much
like film. They have several layers, and the most
important being the emulsion or light sensitive
layer. Paper, however, usually is white, this is
provided by the base. The
base give the other two layers support and unlike
film makes a solid background instead of a
transparent background. The paper is protected by a gelatin
supercoating cover that
protects the emulsion from scratching and chemicals.
..There
are two major types of paper. First there is a fiber
based. Fiber based paper came around before the other
type called Resing coated. Because processing
chemicals are absorbed into the paper, rinsing and
drying takes 4 to 5 times longer than RC papers.
Fiber based papers often are non-glossy. This means
that there is little or no gloss to the final print.
..On the
other hand resin coated papers are less delicate and
can be processed much faster and tend to have a
longer life span. Both type of papers are packaged
and supported by many vendors including Kodak,
Ilford, Agfa, and Oriental. The paper that you will
use will have to be decided by the desired print
contrast and quality.

..Paper
is rated using three variables. These variables are
determined by the surface, weight, and contrast.
..The
Surface varies from smooth (glossy) to highly
textured. A smooth surface is glossy or shiny, while
a textured surface has a matte appearance. Samples of
photo paper finishes are available at nearly every
retail photography store.
..The
weight corresponds to the thickness of the paper.
Fiber-based paper usually comes in single weight and
double weight. Most prints made on a fiber based
paper are single weight. RC papers, however, are
medium weight. Double weight paper resembles the
stiffnes of cardboard and is more expensive than
single weight.
..Most
papers are available in several contrast grades to
compensate for less-than-perfect negatives. By
adjusting the print time and by using contrast
filters, it is often possible to make a perfect print
with a not-so-perfect negative. As the grade value
increases the range between black and white
decreases. Commonly papers are available in 5
different grades.
..Some
special papers called variable-contrast papers are
available. These types are often used by beginners
because they are the most forgiving. They allow for
contrast manipulation through the use of color
filters. These papers are coated with two layers of
emulsion. The first layer is equivalent to a grade 1
paper and the second is equivalent to a grade 4
paper. The grade one is sensitive to a yellow light.
The 4 is sensitive to a purplish light. The filters
have a certain hue that passes more or less light to
a certain layer, making more or less contrast.
..When
you store your paper, always make sure it is nowhere
near any type of light. If you keep it in the
manufacturer envelope, make sure it is always sealed
outside of the darkroom. Also the temperature is very
critical in preserving the quality of the paper. A
temperature below 70 F. is recommended and relative
humbidity between 40 and 50 percent. Always keep the
package containing your paper away from curious
friends who may peek inside and ruining it by
exposure.
