When your the picture you took does not come out the way you envisioned, image editing software can help to improve it digitally. Even if it is from a traditional analog photo, such as an old photo, or an illustration, some of the limitations of the conditions present at the time of shooting can be overcome.
Many very good image enhancing software packages are either free, or they have a trial period so that you can decide which enhancer best meets your needs and budget, as well as letting you see how easy it is for you to use and understand. If your computer is powerful enough, you could even compare the results side by side before making a decision.
To enhance, transform or manipulate images, there are graphic software programs, including 3d modelers, and raster or vector graphics editors. Vector images are easier to manipulate than raster, because the way they are stored on your computer already contains a description of the shapes in the image, which makes them scalable and they can be rasterized at any resolution.
Considerations when choosing an image editing software package may include which formats it reads and writes, such as WMF, JPEG, TIFF PNG, JPEG2000, BMP, ICO, etc., and which scanner and printer models you will need it to support.
