For example, if you start off with a 300dpi image, and enlarge it to twice its size, the resolution will be halved to 150dpi - which is fine for newspaper printing.

If you want to have a large picture in your newspaper, you need to start off with a higher resolution image. The pixels in the picture have to be stretched over a larger area, so if you start off with a picture at 150dpi and you make the picture twice as big, it will end up as 75dpi (half the resolution). Whenever you make a picture bigger, you reduce the resolution. Low-res images can look blocky, pixelated or blurry on screen and in print, like this: The higher the number of pixels, the higher the dots-per-inch (aka dpi or resolution) If you zoom into any picture on your computer screen, you can see that it's made up of pixels (small squares). The number of pixels per inch in a picture is know as its resolution (or 'res' for short).
