21 Sep 08 Choosing Your First Digital Camera
Author: Kirsten Whittaker
Digital cameras are no longer a luxury these days, with high resolution mega pixels and sophisticated features coming within a very appealing price range. And thanks to many comprehensive digital camera reviews, it’s easy to pick the most sought after features and qualities and still stay within a budget.
Most people turn to digital photography because they like the ease of printing and sharing the photos on the web. Business owners choose the digital quality for their product catalogues or brochures, students employ digital cameras for their projects and with digital cameras in most recent cell phones, even a child can take a snap and publish it instantly on the web. And thanks to the newest lens and zooming qualities, you don’t have to be a seasoned pro to shoot close-to-professional images with modern digital cameras.
You can hardly find a digital camera today with resolution lower than 2 megapixels - two million color dots per picture. This is a decent quality for most uses, including printing the photos for the home or school use. The higher the megapixel rate, the bigger photos you can print without sacrificing the quality. However, if you are not a professional photographer or a graphic professional who deals with upscale images all the time, you don’t really need a digital camera that produces more than 8-megapixel camera - and these rarely become available for less than $1000. Plus, if you seek to print large detailed photos, make sure you have a high-quality printer that can reproduces all the tiny details that make a difference.
When you pick a digital camera, you should also pay attention to the zoom number. Digital cameras have two different kinds of zoom. Digital zoom enlarges all pixels digitally, while optical zoom enlarges the image with the lens magnification. Since you can always enlarge the image later, on the computer using the Photoshop or other image manipulation program, you would be better to concentrate on higher optical zoom rate. The average optical zoom for midlevel digital cameras is 2 to 4x.
There are a few other options to consider: whether a digital camera uses a rechargeable batteries (zoom and LCD screen consume a lot of energy); whether the digital camera has a standard flash memory (you may need to buy a few more flash memory cards in future), and if the menus are easy to understand. If you travel a lot, you may want a digital camera that is lightweight and compact.
Even if you decide to pick the least expensive digital camera to serve your basic photography needs, you will still enjoy all the benefits of digital photography: no film rolls to buy, no wasted photos to dispose of and best of all, no waiting time to get them printed. New models of digital cameras are constantly launched, and the older ones are becoming less expensive day by day. Know your priorities, check the most recent digital camera reviews, and there should be a digital camera to perfectly suit your needs.

20 Sep 08 Digital Camera Handling And Maintenance
Author: Roberto Sedycias
A photographic camera is an apparatus for taking photographs or moving film. All cameras have the same basic design - a lightproof container with a lens and a light-sensitive surface. A digital camera is different from a standard 35 mm SLR (single lens reflex) in the sense that digital cameras require no film rolls.
In earlier times careful planning went into taking pictures of an object but with a digital camera you can take a number of photographs and then select the best posture that you have captured while the rest of the pictures can always be deleted without involving any monetary loss. The pictures can then be transferred to your personal computer from where you can take out printouts if you have a color printer installed.
The quality of the photographs in a digital camera depends upon the camera resolution which is determined by pixels. Pixels or picture elements are any of the minute areas of uniform illumination of which an image on a digital display screen is composed. The greater the number of these pixels, the sharper is the image created. A digital camera which offers a resolution of 5 mega pixels is normally considered a good camera.
The weight of the digital camera also goes a long way in camera selection. Once upon a time digital cameras used to weigh one kilogram but with technological advancement they have become very compact and sleek. These modern cameras now come with zoom facilities. You can use digital zoom in any picture-taking mode to get up to 3X magnification beyond optical zoom.
You can do more with your digital camera like using different modes. General picture taking offers an excellent balance of image quality and ease of use. Point-and-shoot simplicity function is provided when taking pictures under special conditions. You can capture video with sound. You can view your favorite pictures. To capture far away scenes, the camera uses infinity auto focus. The camera automatically sets the focus distance depending on the zoom position.
Most digital cameras permit a white-balance setting which automatically transmits by inference which element should look white and which should look black. The lens is an integral part of any camera and determines the quality of the photographs. All digital cameras have LCD screens which can vary in size.
Care and maintenance of your digital camera is of utmost importance. If you suspect water has gotten inside the camera, remove the battery and memory card and allow all components to air-dry for at least 24 hours before using the camera. Blow lightly on the lens or LCD to get rid of dirt and dust. You should always wipe softly with a lint-free and soft cloth or lens cleaning tissue. Never use solutions unless intended particularly for camera lenses. Never allow chemicals such as sun tan lotion, to contact painted surfaces.
For digital camera, battery care is vital. Do not allow batteries to touch metal objects, including coins. Otherwise a battery may short circuit, discharge energy, become hot or leak. Always remove the battery when the product is stored for an extended period of time.
If your budget allows always buy a digital camera that provides you with higher resolutions, longer zoom lens and some other special features. Advanced consumer cameras usually require that you spend some time with the instruction manual to master all their capabilities, but they have few limitations.
Digital camera assures a user friendly working with pictures and videos. If accidentally you delete a picture you can use the undo delete function to retrieve it but this should be done immediately after you delete a single picture.

The type of camera with self-developing film is known as instant camera. Polaroid Corporation makes the famous Polaroid cameras.
Based on the type of film used, Polaroid cameras can be classified. The older Polaroids used instant film roll. Roll films were of two types: Positive or developing agent and negative. These rolls were available in three sizes. Pack film was later used in cameras, in which the photographer has to pull the film from the camera for developing and subsequently the positive and the negative have to be peeled separately while developing. This Pack film was available initially in a rectangular format and later in square format. Subsequent Polaroids such as the once famous SX-70 model utilized a square format integral film, which had the developer, negative, fixer etc in the same film. Development of each exposure was automatic once the shot is taken.
