Solved
edge sharpness increased object film distance
film to be dark over developed,over exposed, developer strong, not enough fixer, exposed
to light,
packet placement for bisecting close to tooth as possible but not parallel
dental film composed of blue tinted polyester acetate
type of safelight filter is used gbx-2
happens in developer reduced silver crystals to black metallic silver
preferred source-object distance (principle of shadow casting) as far as possible
film is put into fixer before developer clear film( all crystals removed)
