1. A method of inspecting an internal feature of a gas turbine component, the method comprising:
- removing a portion of the turbine component to expose the internal feature;
treating the surfaces of the internal feature to provide the surfaces with a substantially uniform coloration;
generating an electronic model of the internal feature;
analyzing the electronic model generated with reference to a nominal electronic model; and
providing an output based on the analysis of the electronic model generated.
