In an apparatus for photographing cavities of the body having a pair of tubular cameras, each containing a film-holding spider;
- a lighting element intermediate said cameras having a filament producing a glow discharge upon application of current;
- a tubular shutter slidably enclosing said cameras;
- means to move said cameras axially of said tubular shutter to permit exposure of said film in said spiders;
- and means to supply air to said apparatus and to expel air into a body cavity, the improvement comprising means for retaining said film in each of said spiders comprising:
- an end cap for one end of said spider;
- a pair of oppositely spaced anchor tabs extending partially axially of said spider from said end cap for holding one end of a film strip in said spider;
