First, a miniature, or any subject in a photograph, should be well-defined.
The \'glowing outline\' background is distracting, as is the \'workbench\' backdrop. A non-reflective, neutral color is the best bet for an attractive, easily recognizable photograph.
I see no problems with a background that includes terrain or a gaming surface, but the depth of field needs to be adjusted so the entire photograph is in focus as this helps to show scale (especially if the terrain is part of a diorama or a battle scene). Conversely, if the background of terrain is only being used for backdrop, and not for a sense of scale, then the background needs to be completely out of focus, drawing all the viewer\'s attention to the subject.
Personally, I prefer a light to neutral grey color, as this serves to:
a.) give the miniature a neutral, well-defined background that does not need to be in focus, and forces the subject to be the only thing the viewer has to judge.
b.)When photographing anything under a studio condition, color-balancing and bracketing is important. A true neutral grey color serves to both balance the color of the subject during the printing process, and helps in bracketing your exposures to achieve the best exposure time for the photograph.
