[D631]Download Digital Camera Pictures
by Roberto Sedycias, Rob
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.

There are many great digital cameras on the market that allow users to take control of elements such as focus, exposure, lighting, and so forth. However, for the majority of consumers, a simple point and shoot camera is the device of choice. Although understanding and using appropriate lighting is critical to produce quality shots even with these cameras, basic picture composition must be the first consideration. If the composition of the image captured is poor, then great lighting, perfect exposure, and so forth will not remedy the problem.

There are a number of "rules of composition" that can be studied but understanding and employing just a few basics will allow even less committed amateurs to produce more enviable images.

?Identify your subject. Every picture should have a single point of interest or subject. Trying to capture an entire scene of activity often produces less than desirable results. It is generally better to focus on individual elements so that a viewer's eye will immediately identify the subject of the image. Therefore, getting up close with the camera and capturing an image of a single tuba player often produces better results than standing back to take a picture of an entire marching band and the audience lining the street.

?Simplify the Scene. This will accentuate the single point of interest by eliminating distracting elements from the scene. For instance, it is better to pose children sitting on the lawn with a backdrop being the carpet of shaded green grass versus a busy playground with traffic moving by in the distance. Reducing this clutter can be achieved a number of ways.

oIn some instances, a simple background can be selected with subjects posed as described in the example above.

oIn other instances, the photographer will need to reposition themselves and their camera to eliminate any distracting elements from the viewfinder of their camera. In a sense, they are cropping the picture as it is being taken. They can step in closer, or zoom in, to cut out the offending background and fill more of the frame with their subject. The photographer can also move their viewing angle by stepping further to the side, higher, lower, or simply turning the camera vertically to cut out some of the clutter.

oAnother technique used by more experienced photographers is to reduce the effect of background elements that take attention away from the subject by purposely taking the background out of focus. The blurry background greatly softens the effect of the extraneous elements and focuses attention back on the main subject.

?Draw attention to the subject. There are a number of ways that the human eye can be drawn to a particular subject within a photograph.

oSome extraneous elements are desirable in photographs; particularly when they give it perspective or draw attention to the main point of interest. For instance, objects in the foreground can frame the subject; a woman framed by a doorway or a child framed by a swing. Other elements can provide perspective: a small kitten surrounded by coffee cups to demonstrate its diminutive size or a fence row to demonstrate the distance and size of a far off towering oak.

oIt is often good practice to position the subject off center when it does not fill the entire frame of an image. Less distracting elements are then left to fill in any void remaining on the opposite side of the scene. For instance, a kitten on the right one third of a shot may be the subject but the small butterfly it is focused upon can add meaning to the scene and fills the space on the left half of the frame. One of the rules of composition asks that the photographer imagine a tick-tack-toe kind of grid over the scene in the viewfinder of their camera. The subject of the photograph should then be positioned at the intersection of a vertical and horizontal line rather than in the space created at the center of the grid.

oLines can guide a viewer's eye. A winding path in the foreground can draw attention to the elderly couple standing at the end, a row of trees can pull the eye toward a fountain flowing on the horizon, and so forth. These are other instances where there is a single subject but other elements are used to draw attention toward its direction.

?Outside the rules of composition. There are a few concepts to take to heart that aren't really part of the tried and true rules of composition that are nonetheless important for amateurs.

oTake time picking the shot. Patience is what often creates great photographers. Those who meticulously move about, reframe, and change their angle of view with the camera are the ones who get the shots that create applause.

oLook closely at what is in the viewfinder of the camera. This is part and parcel of taking time to pick the right shot. Be sure to look critically at the background. Be sure there isn't something in the background that will distract viewers from the subject: Bright scenes on a television in the background, tree limbs sprouting from the head, or ten to fifteen children in baseball uniforms can be distracting to the point of being unable to identify an intended subject.

oTake more than one shot. The ability to take multiple shots without the cost of printing is one of the great advantages of a digital camera. If a photographer wants to capture the field of runners at a track and field event, take the shot. Then zoom in with the camera and focus on an individual runner as he concentrates on a quick start or raises his arms in victory. The decision as to which shot better captures the aura of the day can be made later.

Although the "rules of composition" are more extensive than this, the ability to use these basic concepts can be a huge first step for the novice amateur in using their digital camera to create shots that are worth saving and sharing with the world.
