An electronic camera’s zoom function is fairly just like the one of a video camera and does the same thing, namely bringing individual closer. Anyway, in old digital cameras here i will discuss 2 kinds of zoom, an optical along with a digital one. Optical zoom could be the one similar to the zoom of the traditional camera.
Zoom, conversely, simulates zooming by blowing up a selected area of the picture. It shouldn’t be mistaken with photo editing, which describes applications employed to change the image after it is often produced. Another common misconception concerning this sort of zoom is that it is specially useful for long-distance photos. This is not farther from reality. Optical zoom is much more crucial in a digital camera and it need to be the one used as a criterion comparing different types rather then digital or total zoom.
The caliber of an electronic camera might be more reliant on optical zoom. To create a lot more confusion, manufacturers have started to use the term of ‘total zoom’.

Traditional cameras like 35 mm or APS only had optical zoom. Optical zoom uses an incorporated lens to make the picture closer to the photographer.
Professionals associate digital zoom with digital video cameras. They just don’t consider it a genuine zoom for video cameras since it just enlarges an element of the picture. In other words, it crops part of the image and enlarges others, causing a loss in quality. It truly does work in a similar manner as the cropping and resizing options of photo editing applications. Another new term in digital photography is ‘smart zoom’. This type of zoom avoids interpolation therefore maintains the grade of Iphone Camera .
People sometimes compare optical zoom to resolution after they invest in a digital camera. This won’t make any sense. The effectiveness of digital zoom as well as the resolution are a couple of different things without link to one other. The resolution expresses the amount of pixels in the picture, while optical zoom means the energy the lens. It has not even attempt to do with resolution and might neither increase it nor decrease it. Another tendency is to disable the camera’s digital zoom. Many photographers don’t trust this feature and will want to crop and resize the photo themselves on the computer. This isn’t a really goo practice because it cuts down the camera’s effectiveness.
