I'm reminded so much of the controversy that attended the restoration of the ceiling of the Sistine Chapel. Some art historians and experts insisted that the colors had faded and been dulled over the centuries and that restoring it to more vivid hues was a restoration of its original appearance, while others felt the subdued colors were right and disliked the restoration. Just goes to show you can't please everyone.
In the case of the Sistine Chapel ceiling, restorers used pure distilled water to clean centuries of dirt and varnish from the frescoes. The used water was constantly tested to make sure that no pigments or materials from Leonardo's time were being removed.
The brighter, flatter images that were revealed looked too cartoon-like to some people, who insisted that the artist must have added "toning" layers of paint for shading and modeling over the fresco base -- layers that were inadvertently scrubbed off during the restoration. There's no historic evidence that Leonardo ever did or intended such a thing.
As for the Enterprise
filming model, we know
it never had those heavy gridlines and weathering during series production. They're just plain WRONG.
