At the link below you can download some text files that will make some of the default Amira settings better (IMHO) for 3DEM users.

Some of the changes this will make:
– Rotation disabled by default during slice alignment
– Less aggressive non-local means parameters (on a 2Gb test dataset this also reduced computation tie by 5x!)
– Scalebars will resemble what you see in the literature by default
– Surface View modules are smoother using vertex normal instead of triangle normal
– Generated surfaces have 30 – 50% fewer triangles on average (and are easier on resources!)
– Default Volren colormap changed from red to gray
– Viewer background set to solid black (greatly increases video quality)
– Screen resolution culling enabled
– Camera is orthogonal
Further details and installation instructions are in the README inside the .zip, but I would also be happy to help with any questions.
