An Introduction to Digital Cameras

eiodotcom —  July 14, 2012 — 7 Comments

Today’s Eio post is on the digital camera.

Digital cameras are able to capture images by uploading them onto memory cards, rather than how traditional film cameras capture images onto rolls of film. Because of the new technology of capturing images onto memory cards, digital cameras are able to take multiple shots at high speeds, almost at the speed of capturing a moving picture if enough shots are taken.

In terms of a camera’s identification, the vast majority of cameras can all be identified by the same components. Ehow says this:

A viewing lens is seen on one end that may or may not have padding over it, depending on the size of the camera. On the opposite end is a wider lens that collects light to form an image on film or through digital technology located inside the body of the camera. A flash is found on the front of camera or extending above it. Most cameras also have a shutter button on the top right of the camera body; this is used to take the photos.

Things to think about

Image Resolution

The resolution of a digital camera is often measured in pixel count. The resulting amount of pixels in the image greatly determines the resolution.


The lens of a camera often determines the focus and focal lengths available to each camera. In general, most common digital cameras come with a zoom function, allowing the user to zoom in or out. SLR cameras often need to have separate lens to determine how close or far away one needs to take a picture without physically moving closer or farther.

Image data storage

Digital cameras often come with SD card slots to store data. Users can replace the SD cards to hold more memory so as to take more and more pictures without uploading them onto a computer and deleting the pictures off the SD card.

Types of cameras

Cameras today come in all shapes, sizes, and forms. Most commonly, cameras come in digital camera format or camera phone format. Cameras also are built into surveillance cameras, camcorders, traffic signals, or spy cams. Cameras, of course, come both in capturing still photos, or the ability to record video.
