Samsung Digimax A503
Automatic Setting
An automatic picture on
this camera is just a simple digital photograph without any special effects or
settings selected to make the photograph better looking or different.
Shutter
The shutter allows
light to pass for a determined period of time, for the purpose of exposing
photographic film or a
light-sensitive electronic sensor to the right amount of light to create a
permanent image of a view. These two pictures were taken at different shutter
speeds, listed underneath both pictures.
Aperture
The aperture controls
the amount of
light reaching the
film or
image sensor. In
combination with variation of
shutter speed, the
aperture size will regulate the film's degree of
exposure to light. These
two pictures were taken at different aperture setting, listed under the
pictures.
Shutter and Aperture
Effects
The shutter and
aperture effect how the picture will turn out because of what each does to the
photograph. Both the shutter and aperture will expose the photograph to a
certain amount of light, affecting the picture in itself. The shutter will
create the right amount of light to form a permanent view. The aperture will
increase the depth of field, depending on size. The
smaller the aperture, the greater the distance from the plane of focus the
subject matter may be while still appearing in focus.
White Balance
White balance tells the camera "this object is white." The
camera then shows true white as white and adjusts all the other colors
accordingly. White-balancing is necessary especially indoors under fluorescent
lighting and when moving the camera from one lighting situation to another.
These two pictures were taken at different white balance settings, listed under
the pictures.
Should your camera always
be set on automatic?
You should not
always have your camera set on automatic. In the case of a close-up picture less
than 0.2 m, you should change your camera to the macro setting. Make sure to
maintain the focal range at 0.2 m to prevent the image from being dim. There are
also many special effects on this camera to make the picture stand out from its
surroundings, such as composite shooting, photo frame, and a variety of
shooting situations. This makes the picture different from the automatic
setting. The automatic setting is used primarily for a standard photograph.
Controlling ISO
To reduce blur caused by camera movement,
some cameras let you increase the ISO, although this adds some grain to the
image. Increasing the sensitivity means less light is needed for a picture so
the shutter speed is higher. Increasing sensitivity is a good way to get
pictures without flash in places such as concerts and museums where flash is
prohibited.
Setting your camera to ISO is helpful in
certain physical settings. These include concerts, museums, pictures of
fireworks, or places in a dark location where you
don't have a tripod. These two pictures were taken with the ISO feature on at
different settings, listed under the pictures.
Depth of Field
Depth of field
is the distance in front of and beyond the subject that appears
to be in focus. There is only one distance at which a subject is precisely in
focus, but focus falls off gradually on either side of that distance, and there
is a region in which the blurring is imperceptible under normal viewing
conditions.
Three factors that control depth of field include
Digital Zoom vs.
Optical Zoom
Digital zoom is a method of narrowing the apparent
angle of view of a digital photographic or video image. Digital zoom is
accomplished by cropping an image down to a centered area with the same aspect
ratio as the original, and usually also interpolating the result back up to the
pixel dimensions of the original. It is accomplished electronically, without any
adjustment of the camera's optics, and no optical resolution is gained in the
process.
Optical Zoom is a zoom lens that achieves its magnification by moving parts of
its lens forward or backwards. This usually takes place inside the camera, out
of view, but can often be heard as the sound of a small motor and other
mechanical parts.
Macro Feature
A super macro feature
lets the user photograph subjects as close as 6cm from the lens. You would use
this macro feature when you would want to take a close up picture of an object
to get very close details. The first of these pictures is taken with the macro
feature off while the other picture has the macro feature on.
Controlling Image
Size
You can control the size of your images by changes the settings on this camera.
This camera allows you to take pictures at image sizes of
640 x 410, 1024 x 768, 1600 x 1200, 2048 x 1536, 2272 x 1704, and
2560 x 1920. You can find these settings under the menu button of this camera,
where you can select the image size appropriate for your application.
Exposure Modes
This camera also has different exposure modes that are also featured on most
other digital cameras as well.
These include:
Children
Party
Portrait
Beach
Fireworks
Snow
