Digital photography refers to the process of using electronic and computing devices to capture, create, edit, store and share digital images or photographs. It wraps up several different technologies used to provide electronic or computer-based photography services. It is mainly used as a means to create, publish or use digital photographs on computers and on the Internet.
Digital photography is a form of photography that makes use of cameras containing arrays of electronic photodetectors to capture images focused on by a lens, which is different from an exposure on a photographic film by an analog camera. The captured images are converted to digital files and stored on a computer, and ready for further digital processing, viewing, digital publishing or printing. Digital photography has evolved through many types of recording medium. Commonly, up until the last decade, a large amount of photography was done using an exposure stored on a film that would later be removed from the camera and developed into a full-blown picture.
So digital photography is basically the digital process by which a photo is captured. But the constituents of photography and achieving photography are the same, for example, a digital camera still depends on shutter speed, aperture, and ISO to create an exposure, the same as used in film photography.
The Digital Camera is the tool used for digital photography and bellow are some of the features of A digital camera
Memory: Digital cameras store pictures as data files rather than on film as in analog. The number of pictures you can take before downloading the images to a computer, at which you can easily go back and fill the memory up with new pictures.
Resolution: This term refers to the detail, or sharpness of an image. The higher the number of pixels, the higher the resolutions.
Flash Type: A flash, of course, is the extra light needed by the camera to capture photos inside or in low-light conditions.
Burst Mode: Burst mode is also known also as Rapid Fire and Continuous Shooting mode In general, there is a seconds lag of between 1-2 between pressing the shutter button and the picture is taken with a digital camera. Then there is also a 2-30 second recovery time before the camera is able to take another photo.
Optical Zoom: there are 2 types of zoom lenses in a camera, digital and optical. Digital zoom simply zooms the picture without adding any clarity of detail to it. The same thing can be done with an editing and cropping software. Optical zoom will do what you really want which is to add detail and sharpness. The larger the lens (2x, 3x, which is the standard lens, 4x, etc.) the more picture taking ability you have.
Lens: lens length will determine how much of a view will fit into a picture. Some cameras come with fixed focus lenses, which are preset to focus at a certain range. These pictures are typically focussed on a wide-angle lens and normal range. Many cameras have autofocus, which picks an item in the center of the viewfinder around which to focus.
Power Source: digital cameras use either a rechargeable battery pack or traditional batteries, usually 2 - 4 double A. Some have an AC adapter as well.
Below are some of the benefits of digital photography:
1.Lesser cost: One of the advantages that digital cameras provide is the fact that it is largely practical and convenient. There is a lesser cost in running it for a long period of time as one needs not to buy films anymore and will not develop the pictures in the old fashion way. They would only need to recharge the batteries, get a reasonably large memory and they are set.
2.Better storage: Photographers can now save the pictures that they have taken in their computers and in their CDs, allowing them to use the camera storage over and over again. There is no more need to keep rolls of film and worry that they might disintegrate.
3.Printing convenience: Another benefit of using a digital camera is the fact that it can be printed at home the same way you print any kind of file.
4.Trial and Error: Another benefit of using a digital camera is the fact that one can actually see the photos immediately after taking it and have the option of deleting it when it is not good.
