Those in the market
to buy a digital camera are in the right place!
There are so many terms used when researching, and it’s important to
know what they are, so you get what you need!
Here you will find the most common verbiage when dealing with digital
cameras to help you in your exciting purchase.
First, there are 3
main types of cameras:
SLR (Single Lens
Reflex) - A camera that uses a mirror system to direct light, and can offer
more accurate framing and depth of field.
Because of this, what you see in the viewfinder is exactly what your
picture will be. The user can manually
adjust the lens’ focus, and many other features.
DSLR (Digital Single
Lens Reflex) - The same as an SLR Camera, however this camera stores your
images in digital format on a memory card.
Point and Shoot -
An easy to use camera with limited functions.
Most use autofocus, with flash units that are built in.
Now onto the features
that you should look for, or know about in a camera:
AC Power- Your
camera will be charged in a wall outlet or computer USB port rather than by
traditional batteries.
Aperture- How
much your lens opens through which light will pass.
Aspect Ratio- The
ratio of your images’ horizontal and vertical dimensions. Most cameras have an aspect ratio of 4:3,
but if you are looking to be able to print perfect 4X6 images, then look for a
camera that offers 3:2 ratio mode.
Aspherical Lens-
A lens that is not perfectly spherical, but creates superior images by reducing
or even eliminating aberrations (lighting imperfections).
Digital Image Stabilization- Used to minimize the effect of
blurring or shaking while the camera is in the process of capturing video.
Digital Zoom-
Magnifies the center of an image, keeping the same aspect ratio, while reducing
the amount of pixels.
Exposure- The
amount of light that reaches the photographic film, and is determined by the
shutter speed and aperture
Frame Rate- How
many image frames are shown per second.
The higher the Frames per second, the more “real” or “in person” the
imagery looks.
Image Resolution-
Amount of pixels in the length of an image- Referring to the detail of the
image. The higher the resolution, the
more detailed your picture will be.
Macro- Offers the
ability to focus really well on small objects that are close to the camera.
Megapixel- A measurement
to describe how many dots or pixels are in an image. The
more pixels contained in an image will mean more detail, and more detail in an image
means you can make large prints from your images.
Optical Zoom-
Allows the camera to zoom in on an object without affecting the detail or
resolution of the image. It uses the
lens to draw the image closer, much like binoculars.
Pixel- One Pixel
refers to one spot on an image. Pixels
combine to make up the resolution of an image, and as with most everything, the
more pixels you have, the better your image is going to look.
Shutter Speed- How long the camera’s shutter stays open to
capture an image.
