Introduction of Digital Photography
Author: admin
With the acceptable image quality and other advantages of digital photography the majority of professional photojournalists have begun capturing their images with digital cameras. Digital photography has also been adopted by many amateur snapshot photographers, who take advantage of the convenience of the form to send images by e-mail, placing them on the World Wide Web, or viewing digital photo frames.
Also, a big advantage of digital photography is instant review of images, without waiting for the film to be developed: if there is a problem with a photo, the photographer can immediately correct the problem and take another picture (up to hundreds photographs on the same media device).
Digital cameras have been integrated into many mobile phones. The photographer is able to color balance and manipulate the image so that science can not offer traditional darkroom, although users can use the same technology film with a film scanner. But digital cameras tend to be much more sensitive to moisture and extreme cold. For this reason, photographers who work in remote areas, like those who work for National Geographic overwhelmingly favor film SLR cameras. Many digital cameras can deliver only JPEG files.
Another format that may be encountered is RAW, which contain the raw image data directly from the camera’s image sensor. Compact digital cameras usually include zoom lens and flash can not be changed, but digital single-lens reflex (DSLR or DSLR), operates on the same principles of optical and mechanical, like a film SLR camera and offers the possibility to change lenses. Manufacturers like Nikon and Canon have recently promoted the adoption of digital single-lens reflex (DSLR) to photojournalists. Lenses in the field of digital photography can be a telephoto lens, wide angle or lenss lenss Normal, used for landscapes, portraits and close-ups (macro). Digital anti-shake tools (Image Stabilisation also called) allow taking strong hand pictures where previously a tripod was required. SRLs work with digital RAW images contain unprocessed image data straight from the camera sensor.
Since the data are not processed on the camera the photographer will do it on your computer in order to obtain other useful formats such as TIFF or JPEG. This method offers the flexibility of the results regarding exposure, lighting, white balance, contrast, color saturation and greater creative control and image.
