Overview of Photography
The word photography comes from the word
photo means light and graph a meaningful picture. So photography can mean drawing / painting with light.
Types of cameras
Film cameras, now also known as analog cameras by a few
people.Format movies
Before
we go into the types of film cameras, it helps us to know in advance a
wide range of format / size film.
1. APS, Advanced Photography
System. Small Format with 16x24mm film size, packaged
in a cartridge. Although this format is relatively new, but
popular. Stores that sell this type of movie is hard to
find in Indonesia.
2. Format 135. Also known as 35mm film. 24x36mm
in size, packaged in a cartridge containing 20 or 36 frames. This format is the most popular format, we encounter
many around us.
3. Medium format
4. Large format
Type of Film
1. Film B / W, black and white
negative film.
2. Color negative film. The most popular, we often use.
3. Positive film, also called slide. More expensive and prone to overexposure.
Yet the
resulting colors better because it can capture a wider contrast range.
Types of cameras
1. Pocket / compact. Pocket camera. Popular for the layman,
simple and easy to operate. Using the 35mm film format.
2. Rangefinder. Search camera distance. Small, at first glance similar to a pocket camera.
The difference is, this camera has a
mechanism fokusing (hence called a rangefinder). Commonly used 35mm film
format.
3. SLR, Single Lens Reflex. Single lens reflex camera. Popular
among professionals, amateurs and hobbyists. Generally have lenses that can be
replaced. Using the
35mm film format. Also
called system cameras.
4. TLR, Twin Lens Reflex. Double-lens reflex camera. Typically use medium
format.
5. Viewfinder. Typically use medium format.
Manual cameras and automatic
cameras. SLR cameras are already equipped for
autofocus and autoexposure systems but can still be operated manually.
Digital cameras. Using a
digital sensor instead of film.
1. Consumer. Pocket camera, cheap, easy to use. The lens can not be replaced. Most just have a
full-automatic mode. Just
point and shoot. Some, such as the Canon A series, has a manual
mode.
2. Prosumer.
SLR-like cameras,
medium price. The lens
can not be replaced. Shooting
manual and auto mode.
3. DSLR. Digital SLR.
Lens, the eye of the camera, generally
determines the quality of the resulting image lens has two important
properties, namely the focal length and maximum aperture.
Field
of View (FOV) of each lens has a wide field of view depending on the
focal length and wide film / sensor used.
Field of View Crop, often mistakenly referred
to the focal length multiplier. Almost
all digital cameras have a smaller sensor size than 35mm film, so the
digital camera field of view is smaller than on a 35mm camera. For example a
50 mm lens on a Nikon D70 has the same FOV with 75mm lens on a 35mm film
camera (1.5x FOV crop factor)Types
of Lenses
a. by prime-vario
1. Fixed
focal / Prime, has a fixed focal length, eg 35mm f/3.5 Fujinon has a
focal length of 35 mm. Prime lens less flexible, but the quality is higher than the zoom
lens at the same price.
2. Zoom / Vario, has a focal length that can be changed,
such as the Canon EF-S 18-55mm f/3.5-5.6 focal length can be changed
from 18 mm to 55 mm. Flexible because the focal length can be
set.
b. based on focal length
1. Wide,
wide FOV lens, focal length 35 mm or less. Typically used for
photographing landscapes and buildings.
2.
Normal, focal
length of about 50 mm. Lenses versatile, fast and cheap.
3. Tele, narrow FOV lens, focal length of 70mm or
more. To take
pictures from a distance.
c. based on the maximum
aperture.
1. Fast, has a wide maximum
aperture.
2. Slow, has a narrow maximum aperture.
d. special lens
1. Macro lens, used to shoot from close range
2. Tilt and Shift lens, can be bent.
Terms lens wide / tele (based on focal
length) above applies to a 35mm film camera. Nikkor 50 mm
lens becomes a normal lens on a 35mm film camera, but a telephoto lens
when used on a Nikon D70 digital camera. On the Nikon D70 Nikkor 50 mm field of view equivalent to 75 mm
FOV lens on a 35mm film camera.
Other auxiliary equipment
Tripod, required
for shooting at a slow pace. At
slower speeds, avoiding camera shake when held by hand (handheld). In
general, the minimum speed is 1/focal handhel.
Bring a tripod when
hunting can be a hassle. For
the purposes of hunting usually carried tripod is lightweight and small
tripod.
Monopod,
like a tripod, one leg. It's
easier to carry. Just to eliminate vertical shake it.
Flash / flash / flash, for menerangai objects in dark
conditions.
Filter, to filter incoming light. There are many kinds.
§ UV, filter out UV
light to prevent hazy on foto2 landscape, often used to protect the lens
from dust.
§ PL /
CPL (Polarizer / Circular Polarizar) to reduce shadows on non-metallic
surfaces. Could
be to increase the contrast of the sky.
Exposure, the amount of light that enters the
camera, depending on the aperture and speed.
§ Aperture / diaphragm. The bigger
the aperture the more light entering. Aperture is expressed by numerical values as
follows: f / 1.4 f / 2 f / 3.5 f/5.6 f / 8. the
greater the number (f number), the smaller the aperture aperture.
§ Shutter speed / aperture. The sooner, the
less light to enter.
§ ISO, stated sensitivity of the sensor /
film. ISOnya The higher the number the less light
is needed. ISO 100 film requires 2 times the amount of light
the film ISO 200.
Example: f/5.6 aperture combinations excl. 1/500 at ISO 100 equivalent aperture f / 8 excl 1/500 or
f/5.6 excl. 1/1000 at ISO 200.
Exposure meter, light meter. Almost
every modern camera has an internal light meter. There are
also external light meter.
Exposure
metering (often abbreviated as metering only), the method of measuring
light
1. Average metering,
measuring the average light around the frame.
2. Center-weighted
average metering, measuring the average light with the center of
gravity.
3. Matrix / evaluative metering, Measuring light in various
parts of the frame, and then calculated with the automated methods
specified.
4. Spot
metering, measuring the light only on a small section in the center of
the frame only.
Exposure compensation, 18% gray. Exposure meter always
measure and resulted in the measurement of light so bright the resulting
photo revolves around the 18% gray. So if we shoot a piece of white cloth and
use the exposure setting as indicated by the meter, the white cloth will
be gray in the photograph. To overcome this
we have to make exposure compensation. Exposure so we added a white
cloth.
Under exposured, images are too dark due to
lack of exposure.
Over exposured, images are too
bright due to excess exposure
The
term stop. Up one stop, meaning that exposure was increased to 2
times. Up 2 stop, it means increased exposure to 4 times. Down 1 stop
exposure was reduced to 1/2 times. Down 2 stop exposure was reduced
to 1/4 times.
Increase
of 1 stop on the aperture as follows: f/22; f/16; f/11 f / 8 f / 5.6 f /
4 f / 2.8, f / 2. Unlike any number f stop was 0.7 times (1/Ö2).
Increase of 1 stop in excl. Rana as follows: 1/2000; 1/1000; 1/500;
1/250; 1/125; 1/60; 1/30; 1/15; 1/8; 1/4; 1/2: 1. Different speed is 2 times
each stop.
DOF, depth of field, depth of field. DOF is the sharp area around the
focus.
Depth of field is
influenced by a large aperture, focal length, and the distance to the
object.
1. Aperture, the larger the aperture (smaller f number),
the DOF will be more shallow / narrow.
2.
Focal length (real), the focal length, DOF more
shallow / narrow.
3. The distance to the object, the closer the distance to
the object of the DOF more shallow / narrow.
Election DOF
§ If the narrow DOF, FG and BG will blur.
Narrow DOF is used if we want to
isolate / highlight objects from the surrounding environment such as the
portraits or photos of flowers.
§ If the DOF wide, FG and BG look
sharper. DOF wide use if we want almost all
parts of the picture look sharp, such as a landscape photo or photo
journalism.
Shooting mode
Auto
mode, point and shoot mode, just aim and shoot.
1. Full auto, the camera determines all parameters.
2. Portrait, the camera uses the largest
aperture to narrow DOF.
3. Landscape, the
camera uses the smallest aperture.
4. Nightscene, use a slow speed and
flash to capture objects and BG as well.
5.
Shuter fast speed
6. Slow shutter
speed
Creative zone
1. P, program AE. Similar to auto
mode with more control. In this mode we
can control the exposure compensation, ISO, metering mode, Auto / manual
focus, white balance, flash on / off, and continues shooting.
2. Tv,
shutter speed priority AE. We determine the speed, the
camera will calculate the correct aperture.
3. Av,
aperture priority AE. We determine the aperture, the camera adjusts
the speed.
4. M, manual exposure. We are determining the
aperture and speed manually.
Composition and Angle.
Composition is the placement
of an object in a picture frame
Angle is the angle of
shooting, from below, above, or equal.Composition and
angle more related to the art of photography. Factors photographer
tastes great effect.
