Things To Consider Before Buying Digital Cameras

When digital cameras became commonplace, a question most photographers asked was if their film cameras could be converted into electronic. The first recorded attempt at building a digital camera was Steven Sasson, an engineer at Eastman Kodak. The first true digital camera which recorded images as a computerized record was probably the Fuji DS-1P of 1988, which listed to a 16 MB internal memory card which used a battery to maintain the information in memory.

Digital cameras can include features that are not found in film cameras, for example:

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

– The capability to take thousands of pictures on a single little memory device.

– The ability to capture video with audio.

– The ability to edit pictures and deletion of images letting re-use of the storage they inhabited.

A digital camera is a camera that takes video or still photos, or both, digitally by recording images on a light-sensitive sensor. Most digital cameras quantify subject space automatically using acoustic or digital methods, but it’s not customary to say 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 different signals, replacing the task of a film in conventional photography.

Digital cameras have high power requirements, and over time are becoming increasingly smaller in size, which has caused a continuous need to develop a battery small enough to fit in the camera and able to power it for a reasonable amount of time. Digital cameras are integrated into several devices ranging from PDAs and mobile phones (known as camera phones) to vehicles and even webcams. Webcams are digital cameras attached to computers, used for video conferencing or other purposes.
