Point, Aim, and Shoot!

There is something to be said about the digital camera revolution – it has been efficient. Gone are the days with lengths of expensive film to have developed, hoping that somehow you were able to get off the perfect shot. With digital camera technology, there have been several innovations that have made taking photo’s that much easier as well as improving the function and form of the cameras themselves. Digital cameras are smart, practical, vary in any number of sizes and can be used for any purpose – from the professional newspaper photographer to a family member trying to capture a moment during holiday.

For the first time buyer, actually purchasing a digital camera can range from difficult to problematic. When it comes to digital cameras there are literally hundreds of cameras available at many different types of brick and mortar stores such as Best Buy and Kit’s Cameras to online buying sites such as Amazon with prices ranging from $75 to several thousand dollars. There are some cameras that are small enough to fit in a shirt pocket while other digital cameras are enormous and can weigh up to two pounds. Some digital cameras are easy to use while others may require a certain amount of technical expertise or even classes. What makes it even more difficult is that most digital cameras do not have clear markings and can often times confuse the owner.

What is most important is for the buyer to be aware of what a digital camera is and how it works. In the past with a film camera the image is created by collecting light from a particular scene or subject and focusing on film which then reacts chemically when struck by light and essentially captures the image. What sets a digital camera apart is that instead of film the camera has an image sensor that reacts to light via sending out electrical signals, thus rendering the image for the camera.

How Functional are Digital Cameras?

Essentially the digital camera will take the information from the electronic image sensor and then processes and stores it as a collection of pixels inside a digital file which is usually stored on a memory card inside the camera – though they can often times be removed and hooked up to a USB device that will allow instant download onto a personal computer. While the process is somewhat more complex than described this is essentially how a photo digital image is created. A single digital photo is made up of hundreds of thousands of pixels depending on the quality settings of the camera.

As the digital camera collects a million pixels that is commonly referred to as a megapixel. It is the number of megapixels which tells you how many pixels that the image file has available. For example: a camera that captures 8 million pixels is called an 8 megapixel digital camera. The number of megapixels a camera features may also help to determine the size photos that can be printed or the amount of cropping or editing that can be accomplished.

With some digital cameras their usefulness may be determined by their megapixel count. In the case of a 6-megapixel camera may be the best for the consumer since higher resolution doesn’t necessarily create better prints for the photographer. Other factors contribute to photo and picture quality, such as lenses, filters and flashes. However, it should be noted that most cameras manufactured these days have at least 10-megapixel capabilities. A buyer should also take note of the size of the sensor and the size of each individual image sensor element, which corresponds to pixels and how they can affect the overall photo quality. It should be noted, however, that the sheer number of megapixels doesn’t necessarily determine the quality of the digital camera’s images that it captures.
