P3D Question on use of flash guns

["Dr. George A. Themelis" <DrT-3d@xxxxxxxxxxxxxxxxxxxxxxxxxxx>]

I wonder how useful flash guns and flash bulbs are for stereo
photographers today?  I undestand that flash bulbs deliver much
more light than regular compact flash units and that some stereo
photographers who need lots of light (like those exploring caves)
sometimes prefer flash bulbs to electronic flash.  Is this correct?
Any other reasons someone would use flash bulbs?

Also, are flash bulbs made today new or do these people rely in old
stock?

(I would to include this information in tbe section of the Realist
book that deals with Realist flash guns)

Thank you!

George Themelis
