New Technology in Digital Photography
Earlier to take photographs, photographic films were used, images created and photographic processing was done to make the photos visible for all to see as pictures. In digital photography, digital technology is used to make digital images of people or any pictures that fancy us. This is then stored digitally in computers. No chemical processing needs to be done. The pictures can be stored, retrieved whenever we want, transmitted to any one we want to send it to, printed and also displayed.
The pictures can be taken with the help of a digital camera. The digital film is made up of flash memory modules or recordable CD's. This can be transferred to the computer and stored there. In the computer, the photos can be made to look better with digital technology. The color of the picture, the background, the main image in the photo and the lighting can be made to look different and better. It can also be put on a website.
Digital technology gives the pictures a longer life as opposed to the camera print. We no longer need to have prints. We can see in on the computer whenever we want to. We can sent to near and dear ones far away.
Digital photography is a form of digital imaging. This can be done without a camera. It can be done with computer tomography scanners and radio telescopes without photographic equipments. Digital images can be made of conventional photographs, thus helping in restoring old photographs and helping in keeping memories alive.
Digital photography is the order of the day. Nowadays no one uses the conventional camera. Many new techniques have been made to improve the technology of digital photography. Every aspect of photography is advancing. New strides are being taken in all fields of lighting, optics, sensors, processing and display. There is also new software to integrate all this.
Normal images can be transformed into 3D images. This looks good when viewed from different angles. Making 3D images is very computer intensive. Models of famous places can be seen with the help of Microsoft Photosynth.
High Dynamic Range Cameras and displays are available. With a non-HDR camera a HDR a person can create his/her own HDR image combining multiple exposures. Dust Reduction Systems are also being put in digital SLR cameras to keep the dust of the image sensors of the camera.
A new technique is now used in museums. Using computer controlled lights and sensors; an object's specular reflection is captured. This helps in taking pictures of oil paintings. This is not available in the market. Another feature is the removal of motion blur with the help of a flutter shutter. This is also not available in the market. Other areas that have improved are computer software, displays, enlarged gamut sensors and computer controlled lighting.
Various new techniques are being worked on and thought of by the companies that produce digital cameras and those who are into digital photography. Every now and then we hear of newer advances which improve the quality of photographs and help to restore the old ones that we possess.
