The authors name of " High Contrast " was spelled J. Seely not Sealy
. Also he was making enlargements thru frosted glass not at the negative
plane but enlarger printing thru a frosted glass surface positioned at the
baseboard ( rough side down ) in contact with the ortho film emulsion
taking care not to scratch the negative making enlarged negatives ... The
combination of the film grain and the frosted glass show a dramatic
increase the detail . He was using a point light source.
