Digital Camera – the Easy Way to Take Pictures
In comparison to film cameras, digital cameras have number of advantages which includes displaying the image on the camera screen right after recording, a single small memory device can record thousands of images, records video with sound, provision to edit images, and above all storage capacity can be re-used by deleting the images. There are numbers of devices available that has in-built digital cameras like mobile phones, PDA`s etc. Specialized digital cameras are fit into astronomical devices like The Hubble Space Telescope.
Digitizing images on scanner and digitizing video signals are much older than making of still images using digital signals from an array of discrete sensor elements. It was then used for astronauts to provide onboard navigation information during their visit to planets. It provided the still photos of stars and planet locations during transit and also additional stadiametric information for orbiting or landing guidance while approaching planet.
Steven Sasson, an engineer at Eastman Kodak, attempted to develop first digital camera with solid state CCD image sensor chips. But it was just a technical exercise. The true digital camera was Fuji DS-1P developed in 1988. And the first commercialized camera was Dycam Model 1 in 1990. Then in 1991, Kodak launched its Kodak DCS 100. Else Casio QV-10 was the first consumer camera in 1995. Nikon D1, a 2.74 megapixel camera was the first digital SLR developed in 1999. And in 2003, Canon 300D, first 600 megapixel camera was launched.
There are various types of digital cameras available. For videos, there are professional video cameras which are used in television and movie production. Camcorders come with inbuilt microphone and a small liquid crystal display to watch video while recording and playback. One can get still photographs also with them. Webcams, attached to computers, can capture full-motion video and are also available with microphones or zooming ability.
In live-preview digital camera, there is an electronic camera that can be used to frame and preview before taking the photograph and also to review stored photographs. Many of such cameras can take motion pictures. Then the recorded images can be transferred to computer, printer or any other such device. USB mass storage device enables the camera to function as disk drive for computer and Picture Transfer Protocol is then used.
To use Firewire, storage device is removed from camera and inserted into other device. Compact digital cameras, small and portable with inbuilt flash, are easy to use, and images are stored using Lossy compression. They might be able to capture motion picture but that to a limit. Bridge or SLR like camera is higher-end-live-preview camera with more advanced features like superzoom lenses, takes movies with sound, etc. Digital rangefinder, a user operated mechanism, is capable to measure subject distance.
Apart from above mentioned digital cameras, there are other categories also. Professional modular digital camera systems are used in studios for commercial production. Line-scan camera systems, based on focusing mechanism, are used in industrial settings to capture images of constantly moving materials. They capture images at extremely fast with high image resolutions.
Most of the digital cameras come with pre-set modes for different applications. Data can be transferred through USB port, Firewire port, USB PTP mode and even through wireless connections like WiFi, Bluetooth etc. These data are mostly stored in Microdrives, Joint Photography Experts Group (JPEG), Tagged Image File Format (TIFF) and RAW. Formats for movies are AVI, DV, MPEG and MOV. Recently MP4 format is also developed. Digital cameras have small but powerful batteries to operate for enough length of time.

Canon Digital Camera: the Better Way to Move in Past
There was an era when the past good times that we had lived happily were the matters of our memories only. With every new joy, those good times of past were being vanished from our memories and re-living them became so hard for all of us. Then the age of Art arrived and we all learnt to stock our memoirs in the form of paintings and sculptures. However, the boundaries of these methods were limited and hectic. The human culture was demanding more, then, in 1660’s the English Scientist Robert Boyle with his assistant Robert Hooke developed the first portable camera. This device was capable of capturing the events, thus, the humankind found their way to re-live their life. From the day of its inception, the camera has seen various changes in its style, performance, capabilities and looks.
From camera obscure to the modern analog cameras, the history of cameras is itself a legend. The concept of logarithmic camera was first reached its destination in the year 1972 and we got our first bona fide digital camera in the year 1990 with the name-tag of Logitech Fotoman. This camera made the use of CCD Image Sensor; it had the capability of storing the pictures digitally and making them available to download them in PC. From the year 1991, various companies such as Kodak, Fuji, Sony and others started manufacturing the High-end Digital cameras on very large scale. Their attractive products ranged from Simply Digital to the Professional Digital SLRs. When we aim these cameras at the object and fiddle with the shutter release button, the camera robotically focuses on the object and digitally takes a reading of the obtainable light and then with the help of the processor, CCD and ADC it interpolates the pixels to create crystal clear pictures.
Nowadays, having a digital camera is a non-stop passion for every one. There are many companies in the market, who manufactures these digital photographic engines, but some of them are prodigious. Canon is also among those prodigy masters. This giant offers very huge range of products from different categories. They also offer a superior range of digital still and video cameras. Canon Digital Cameras are one of the most significant products that are currently available in the market. These cameras employ high-quality features and tools to make them more efficient in the terms of quality and performance. These numerical photographic machines hold high-quality mechanism and the superb understanding of all colours so that they can easily tender the eye-pleasant lively images. Fathered in the year 1937, the Canon is now one of the biggest companies that offer qualitative technology for the cameras and optics. This company has redefined the way the world look at its past.
Canon has mind-blowing categories of digital cameras in its shelf. These categories hold the range of all way simple cameras to the superbly effective professional ones. These categories are- Digital Compact Cameras and Digital SLR Cameras. The Digital Compact Camera Category is consisting of two superb series named as IXUS and the PowerShot. Both of these series offers the cameras of astounding styles and great performances. The IXUS includes the cameras that are known as the ultimate Style Icons and combines unending grace with the avant-garde technology. In addition, the PowerShot series covers the range of point-and-shoot cameras. These masterpieces are amazing in looks and they capture brilliant images to cater the photographic feel of all levels. Digital IXUS860, Digital IXUS950, Digital IXUS960, PowerShot G9, PowerShot S5, and PowerShot SX100 are some of the highlights of the IXUS and PowerShot Series.
Whereas, the EOS Series of Digital SLR Cameras are the most widespread approach Digital SLRs. These digital cameras provide sparkling and snappish images with every shot. These cameras are admired and appraised by the photographers worldwide. Ranging from 10.1 MegaPixels to the latest 21 MegaPixels of superior CMOS resolutions, the EOS Digital SLR Cameras are making the world our playground, where we can reach to the new dimension creativity. If the life is all about finding new things then the Canon Digital Cameras are the ever-best things to find and explore.
