Photo Restoration Software
There are some alternatives to Photoshop, but here is the problem with many of these software packages: limited documentation. If you are a beginner, you need as much documentation as possible and Photoshop has just that. Indeed it can look like a really intimidating piece of software, but in terms of photo-restoration, there are just a handfull of tools that you need to learn,and these tools work icredibly well compared to other software packages. I would suggest going to Amazon.com or any large book retailer and picking up the book Adobe Photoshop restoration and retouching. I provided a link below.
