operator to resolve the issue manually. Other tools require a human to analyze
the imagery and change it accordingly.
Semi-automated geometry correction tools are by no means a panacea for
all geometry issues. As with all image tools, geometry correction tools come
with a certain amount of marketing hype and performance claims. In reality,
not every tool is right for every show. In fact, some of the automated tools
can choke when imagery contains multiple non-obvious geometry issues.
In some cases, the software simply interprets imagery incorrectly and it is
up to the human operator to resolve any misapplied corrections. Above all,
avoid choosing your geometry correction tools based only on the editorial
system you use.

Plug-ins are software tools that enable teams to modify geometry, in some
cases based on the results of image analysis.
