You later can 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.
If you already have read Part 1 of this tutorial series and our GIMP Overview article, you might want to skip right on down the to the Overview of Today's GIMP Tutorial or the Preview of GIMP 2.0 section of today's tutorial.
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 Part 1 of this tutorial series plus 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.
For more information about The GIMP, please see our article Overview of The GIMP - a free photograph and digital-image editing program. Also, to get up to speed with today's tutorial please see the first part of our GIMP tutorial series, How to Use GIMP for Photo and Image Editing. It shows you GIMP desktop basics and how to crop and scale (resize) photos, along with how to adjust the brightness and contrast of photos and images.
Overview of Today's GIMP Tutorial
In today's tutorial, let's use the GIMP's powerful layer tools to 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 layer 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. 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 5.
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.
All the figures in today's tutorial were made with the GIMP version 1.3 opened in SUSE Linux Professional 9.0 and the KDE desktop. Screen shots were made using the GIMP's screen shot feature.
Preview of GIMP 2.0
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. Because GIMP 1.3 is the development version for GIMP 2.0, today's GIMP tutorial and Part 1 of this tutorial series are in effect previews of GIMP 2.0.
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's powerful layer tools. 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.
Some of the instructions in today's tutorial direct you to the Menu Bar on the canvass window. However, the pre-1.3 versions of the GIMP do not have a Menu Bar on the canvass window.
If you do not have a Menu Bar on the canvass window, alternate click (right-click if you are using a right-handed mouse) anywhere on the canvass. That pops up a menu that has the same menu options as does the Menu Bar on the canvass window.
