An Overview of Digital Cameras


Digital cameras are amazing gadgets. Just like film cameras, these devices are able to capture and store images. Although similar in many ways, there are certain things you can do on a digital camera that is just not possible with its older counterpart. The digital version allows us to view, save, delete and edit captured images. If you are not satisfied with a picture you took, you can simply delete it to save memory. You cannot do that on a film camera. Most models can even capture sounds and videos. Since these devices use memory cards, the number of pictures & videos that it can hold is only limited by the capacity of the card. As soon as the memory card is full, just insert an empty card and you are good to go. There are two types of digital cameras, Digital Point-and-Shoot cameras and Digital SLR’s. Let us discuss this a little further to see the differences between the two types.

Digital Point-and-Shoot cameras, also known as compact cameras, are small and generally inexpensive devices that are widely popular due to their size and simplicity. These are still cameras that do not require any particular technical expertise to use. These devices commonly include built-in features such as autofocus optical zoom, digital zoom and built-in flash. These gadgets are ideal for general everyday photography where image quality is not a primary concern. The quality of the images captured varies depending on the camera therefore; it is wise to do your research first before buying. You should also consider other factors such as the quality of the lens and the sensor technology of the camera when choosing.

Digital Single-Lens Reflex cameras or DSLR’s are digital counterparts of the older film-based SLR’s. These devices produce high-resolution images with higher megapixel ratings and are significantly more expensive. These high-end cameras feature interchangeable lens, mode dial, depth-of-field control and available only recently, live preview. This feature was not available on earlier models of DSLR’s because of the way images are diverted to the viewfinder. Modern DSLR’s, however, now include live preview as a standard feature. Unlike compact cameras, DSLR’s include what-you-see-is-what-you-get previews. This means that what you see in the preview is exactly what the saved image will look like. This provides the photographer with an easier way to see the images before taking the shot. Please take note that DSLR’s are not the same as Bridge cameras. These devices look like DSLR’s but are in fact more similar to the compact camera.

Cameras have gone a long way from the old film-based models. What used to be a simple image-capturing device has now become a high-tech gadget. With more and more innovations being introduced on new models, you can be sure that camera technology will only get better. If you are planning to purchase one for yourself, it is wise to get down to the basics first. What is your purpose for buying a camera? How much money are you willing to spend? It does not have to be a complicated process. Just answer those two questions and you will eventually choose the right one for you.
