Have
you ever wondered where modern photography
originated? While we are now moving into the digital
age and away from film, the lighting techniques and
other photography techniques began in the 1820's.
Niepce and Daguerre were the first inventors of
modern photography. They used a chemical component
from silver and chalk, which darkens when exposed to
light. This type of technology used a glass negative
to cement the picture.
From the early cameras seen in western films we have
moved on to manual cameras with film. This film or
negative captured the image on a roll to be
developed in a dark room to prevent over exposure.
The manual cameras used a theory of setting up
shots. You had to understand aperture, shutter
speed, white balance, and metering to obtain the
best picture possible. This meant you spent a lot of
time setting up the shot and had to be a
professional to catch wildlife in their natural
habits.
Aperture is measured by F-stops, or the amount of
light the lens will let in. Focusing and depth of
field are also important when setting the aperture
on your camera. You have to know what numbers will
allow more light to enter the lens and the converse
to avoid over exposure and blurriness. Shutter
speed is the amount of time a lens is open for the
picture. You may have found in a darkened room
without flash your camera takes a while to imprint
the picture on the negative. This is because the
light is dim and the shutter must correct for the
lack of light. The lack of light induces a need to
expose the film longer to obtain the picture where
as more light will have the shutter moving at a
faster speed.
From the manual cameras we moved into the automatic.
The camera became lighter. The shutter speed and
aperture was programmed into the camera by the
settings. ISO became important. ISO is the film
speed. Instead of taking minutes to set up a shot
you just had to pick the correct setting and hold
the button down to focus. Many cameras came as
automatic with manual options for those who still
liked to treat photography as an artistic vocation.
Digital cameras are the new era in photography.
Now we can see the picture we take without the use
of film and negatives. We can send the pictures to
all of our friends and use our home printers to
create prints. Photography has moved from the
concentration of taking the perfect shot with a
skill born to a few to everyone taking pictures.
This is not to say photography and photographers
will not remain. There is still the need for quality
in taking professional grade photographs. Light
sensitivity is still important when dealing with a
digital camera and unless you spend a lot, you will
find quality of photographs is still missing.
Photograph techniques lay within the lighting
provided whether natural or artificial for the
subject. You might wonder how to create a photograph
in a dark room like a museum to share with your
friends and family. Knowing the past photography
techniques will help you in attaining that perfect
photograph with your digital camera. Photography may
have originated with few people, but we can see the
advancements their inventions have led us to now.
