Don't be fooled by a pretty "face".

To the right are two 18th century violins as they appear in a photograph. The ff holes have been anonymized.

When you roll-over with your mouse, you see the density map produced by our software. A violin top in perfect condition will look almost like the raw wood, meaning with grain lines running the length of the top. Anything you see that is not going from the top all the way to the bottom is some type of repair or defect.
 

Between the ff holes, the section that is slightly lighter in color is showing what is referred to as a "breast patch."  This work was done to reinforce areas previously repaired. The smaller rectangles are support cleats for cracks.


On this instrument, the black areas are worm damage tunnels and the white areas are attempts at repair.
