Digital Camera vs DSLR
The word “photography” is derived from the Greek words phōs, which means light, and gráphein, which means writing. In this sense, photography means writing or painting with light. Cameras are the tools we use to achieve these photographs. The most advanced of these cameras are the digital cameras and DSLR cameras. Digital camera is one of the most important revolutions in science and technology recently. The applications of digital cameras are enormous, and there are digital cameras in almost everyone’s household item list. When using something it is good to know the roots and origins of it. Digital cameras and DSLR cameras have their own histories. These are some of the most technologically advanced and sophisticated tools we use almost on a daily basis to our convenience. There are virtually hundreds of camera manufacturers, and their technologies vary from each other. In this article, we are going to discuss and compare what digital cameras and DSLR cameras are, their pros and cons, basic usages, equipment used with these cameras, their similarities and finally differences.
Cameras were originally based on a film of light sensitive materials acting as the photo capturing method. Later as technologies such as charged coupled devices (CCD) and complementary metal oxide semiconductor (CMOS) developed the sensor later became a layer of light sensitive electronic components. These components are laid out in a perfect two dimensional array to make the face of the sensor. The light coming from the lens makes an image on the surface of the sensor; the focusing mechanism of the lens then focuses some parts or the whole photograph depending on the setting. The aperture of the camera then opens up to let a previously defined amount of light to enter the camera. This is done by controlling the aperture value and the shutter speed of the camera. Then the incident light on the sensor is converted into a digital bit pattern, which only consists of ones and zeros. This is saved in the memory of the camera sometimes compressed or sometimes uncompressed. Some of the compressed image formats are JPEG, TIFF, and GIF. An example of an uncompressed image format is RAW. Most of the digital cameras can also record videos. These videos are saved in either motion JPEG or AVI. Most of the digital cameras have facilities such as auto focus, face detection, automatic scene selection, automatic white balance and smile detection.
DSLR stands for the term digital single lens reflex. DSLR cameras are an advanced type of digital cameras. It uses a separate lens and a body both of which are very expensive than normal point and shoot digital cameras. These lenses are of high quality; also, have a very large lens opening than the normal cameras, therefore, the sharpness of the images is significantly high. These lenses and camera bodies have fully manual and automatic control over the photo ranging from white balance to focus points.
What is the difference between Digital Cameras and DSLR Cameras?
DSLR cameras are basically a more advanced set of digital cameras. Digital cameras are an array of equipment, which is capable of exposing and storing images and videos, but DSLR cameras are specially made for photography. But most of the DSLR cameras also have a video recording facility.
