Digital camera - Research Paper Example

They all come in difference sizes, features and of course with price variations from two figures to four figures. It therefore becomes all the more necessary that we must go for a camera most suitable for our requirements. Some of the key features in modern day digital camera are; i. Resolution: i.e. a key determinant of picture quality. This indicates the number of pixels or picture elements that can be packed inside the picture. More the pixels clearer will be the picture, because that implies the picture can have more details in it.

Now a days, we talk of megapixels i.e. million pixels. The number of megapixels also limits the size of the print that we can take from the picture. And if we try to enlarge the picture further, it becomes blurred or broken into squares. Some of the standard sizes for print are; ii. Types of Lens: The lens is another very important feature of the camera. In fact the lens happens to be the first thing that will create the picture. The lens could be made up of plastic or glass. The clarity of glass lens is much more than their plastic counterparts.

Normally Carl Zeiss offers good quality glass lenses. But the cost of glass lenses becomes more. Another distinguishing feature for the lens is the zooming facility. A zoom lens we can take clearer pictures of distant objects. The zoom lens allows us to magnify or shrink the subject to include more area in the picture. The zoom comes in the form of 2X, 3X, 4X etc. As the zoom range goes up so does the price of the camera. In addition the digital camera comes with digital zoom as well, which is helpful for cropping up the picture. iii. Shutter Speed: We need to be more careful about this future while purchasing manual cameras, because the shutter speed determines the duration of the exposure time.

The slower the shutter speed, the more will be the exposure. In this case the picture will be able to record more depth of the picture. But, if during the exposure time there’s some shake
