In this tutorial you will learn how to edit or enhance the color of an image. For example, you might be so uncomfortable seeing a dim or blurry part of your group picture but you’re helpless you don’t know how to make it more pleasing to the eye. Neither you have an idea if there’s a way to edit or correct it so you can be proud to show your friends how great a picture you have. Well, not now that you come to this place… a place where you can learn the basics and more advanced knowhow in image editing via Gimp program!
