You can later apply the basic skills, elements, and principles that you learn in this tutorial to edit and manipulate photos, clipart, scanned images and other digital graphics. You also can use the GIMP to design and create all sorts of stunning computer graphics and images from scratch. However, today's tutorial focuses on editing already existing images with the GIMP.
Originally, GIMP was a Linux/UNIX program. However, it has been ported to the Microsoft Windows platform -- that effectively makes GIMP a cross-platform (XP) program. There appear to be some Mac versions of the GIMP now also.
The GIMP and Adobe Photoshop are comparable, digital-darkroom, software products as to features, functions, and usability -- other than some advanced professional and prepress stuff in Photoshop. The basic photograph and image cropping, scaling, color-brightness adjustment, and color-contrast adjustment operations covered in today's tutorial are just as easily done and well-done with the GIMP as with Photoshop.
Moreover, GIMP is free and Photoshop costs $699. Because GIMP is an excellent, pixel-based, image manipulation and editing program and because of licensing and pricing issues, we chose to use the GIMP rather than Photoshop in our digital darkroom. More about the GIMP and Photoshop further on in this article.

Overview of Today ' s GIMP Tutorial
In today's tutorial, let's edit one of the photos from the Goose series used in the GIMP Overview article.
The purpose of today's tutorial is:
Thus the focus of today's how-to article is on the basics of using GIMP's cropping, scaling, brightness adjustment, and contrast adjustment tools. You will learn how to use these tools by editing a digital photograph.
If you have a digital camera, the GIMP is an important tool that you should have in your digital darkroom. Please see About the Digital Darkroom in the right-hand sidebar.
The GIMP is included with many prominent GNU-Linux distributions. If you have a major GNU-Linux distribution such as Mandrake or SUSE, you likely already have the GIMP.
If you are an MS Windows user you might not already have the GIMP installed. The good news is that whichever of the above listed OSs you use; you can download and install the GIMP at no charge to you. Download links are in the Resources section at the end of this tutorial on page 4.
Figure 1, below, shows the GIMP version 1.3 opened in SUSE Linux Professional 9.0 and the KDE desktop. The Geese picture to be edited is in the upper right of the screen shot.
The next major GIMP release will be GIMP 2.0. The current end-user version is GIMP 1.2.5. In between those two versions is GIMP 1.3.x, the pre-2.0 developers' version.
Since this tutorial is based upon GIMP 1.3, it should also be applicable to GIMP 2.0 when it is released. The tools used in today's tutorial also are in GIMP 1.2.x. Thus, this tutorial also is applicable to GIMP 1.2.x.
The Hands-On GIMP Tutorial
There is no one, single, way to go about taking pictures or editing them. There are different tools that you can use, even within one photo-editing program. Moreover, there are different ways to use those tools. The way this tutorial shows you how to do your digital-darkroom work is just one of many approaches.
This tutorial shows you the mechanics of basic photograph and image editing with the GIMP. Unfortunately, photograph and image artistry is beyond the scope of today's tutorial.
However, it is much more the photo artistry than the mechanics that makes great photos and graphics. If you are a college student, take a studio (art) course to learn artistry basics. That is a real hands-on studio course not some wimpy art appreciation course. Or if you are not a college student, take a real, hands-on, studio course at your local community college.
