Hi Jerry, Thanks for posting this movie film ad from 1930. More information is always helpful. Several online sources reaffirm the 1904-1906 release of panchromatic film stock. Panchromatic stock for still photographic plates became available commercially in 1906. https://en.wikipedia.org/wiki/Panchromatic_film is one with a footnote reference. Another sorce lists 1904. I think if this image had been shot with ortho film, the Q herald would not have tone. The bright red should turn black. Sorry to the daily digest folks for not being able to trim this post. I gave up. Randy ---In CBQ@yahoogroups.com, <jeralbin@...> wrote : For those still interested. Also, note the date. ..Regards Jerry Albin
