Basic techniques for better images

A digital image is made up of a collection of small dots called pixels.

If it contains a large number of pixels, the image becomes large, it takes up more memory, and

the image is displayed in fine detail. “Image size” is shown by the number of pixels. Although

you cannot see the differences on the screen of the camera, the fine detail and data processing

time differ when the image is printed or displayed on a computer screen.
