There are several ways of dealing with image problems. One is to make use of the tools in PHOTO-PAINT, which for many applications are more than enough for the task. Other times it’s best to make use of plug-ins, since these tools, often specialized, can reduce the time it will take to fix the problem. As a case in point, Barrel and Pincusion distortion are possible to fix within PHOTO-PAINT, but the process is labour intensive and it’s pretty much impossible to automate it. In contrast, if you use plug-ins, such as the one available from HumanSoftware, you can quickly make the corrections, then save what you’ve done as a preset for future use.
