Digital Cameras – the Constant Innovation and What to Look for When Buying

Posted on December 18th, 2009

Main Concept And Evolution

When digital cameras became common, a question many photographers asked was whether their film cameras could be converted to digital. The first recorded attempt at building a digital camera was by Steven Sasson, an engineer at Eastman Kodak. The first true digital camera that recorded images as a computerized file was likely the Fuji DS-1P of 1988, which recorded to a 16 MB internal memory card that used a battery to keep the data in memory.

Digital cameras can include features that are not found in film cameras, such as:

- Displaying an image on the camera’s screen immediately after it is recorded.


- The capacity to take thousands of images on a single small memory device.


- The ability to record video with sound.


- The ability to edit images and deletion of images allowing re-use of the storage they occupied.

A digital camera is a camera that takes video or still photographs, or both, digitally by recording images on a light-sensitive sensor. Most digital cameras measure subject distance automatically using acoustic or electronic techniques, but it is not customary to say that they have a rangefinder. The resolution of a digital camera is often limited by the camera sensor (typically a CCD or CMOS sensor chip) that turns light into discrete signals, replacing the job of film in traditional photography.

Digital cameras have high power requirements, and over time have become increasingly smaller in size, which has resulted in an ongoing need to develop a battery small enough to fit in the camera and yet able to power it for a reasonable length of time. Digital cameras are incorporated into many devices ranging from PDAs and mobile phones (called camera phones) to vehicles and even webcams. Webcams are digital cameras attached to computers, used for video conferencing or other purposes.

When You Buy Digital Camera

Measuring the “pixels per dollar” as a basic measure of value for a digital camera, there has been a continuous and steady increase in the number of pixels each dollar buys in a new camera consistent with the principles of Moore’s Law. Before you buy digital camera, it is important to determine what kind of pictures you want to take with it. Be sure to check first its capacity to produce high quality photo images and don’t forget about camera’s batteries – make sure they are rechargeable.

When you buy digital camera, sometimes the spending does not end there. For instance you may want to buy additional memory if the one that is already included doesn’t suit your need and its capacity is not enough for you. This is why you must make sure that the gadget that you buy has not only a “built-in” memory or a card slot for external and additional memory, but also includes memory card with good enough capacity.

The LCD is a special consideration you have to look into when you buy a digital camera. This is a small screen located at the back of a digital camera that allows you to preview the pictures you took. This has to be considered when you buy digital camera, because it uses up a lot of battery power.

It is essential for you to feel comfortable holding your digital camera while shooting. So, before you buy digital camera, the right thing will be to test and check if you are comfortable holding it and using it. Special features that will suit your needs should be thought about, too before you buy digital camera. No matter what your needs and wants are for the device, your financial resource will play a huge part in dictating the type of digital camera you will buy. When buying digital camera in online store, make sure you already know what you want and start sorting by lowest price first and later calculating shipping and sales tax.

With these information, you can now figure out what you really need and want before you buy digital camera.
