Generation loss

Hello! Have you ever made a copy of a picture or drawing on a piece of paper using a pencil or a crayon? When you copy something like this, there could be a loss of quality or details in the new copy that you made. This is called generation loss.

Let's say you draw a colorful picture and you want to make a copy of it so you can share it with your friends. You use a copier machine to make the copy. The first copy you make of the picture looks pretty good, but when you make a copy of the copy, you might notice that the colors are not as bright or the lines are not as sharp as the original picture.

Each time you make a copy, you lose some details and quality. This happens because the machine is not able to perfectly copy every single detail in the original picture. So, as you make more copies, you lose more and more details until the picture becomes blurry, unclear, or even unrecognizable.

Generation loss can also happen when you make copies of digital files like music, videos, or images. It's important to be mindful of generation loss when you want to preserve the quality of something. To avoid generation loss, it's best to make copies directly from the original source whenever possible, or to use high-quality equipment when making copies.
