Panchromatic = sensitive to Red & Orange
Panchromatic = sensitive to Red & Orange
I think the shtick here is that this is one of the "new-fangled" Panchromatic films, sensitive (as the ad points out) to all colors. The "high speed" claims are directed towards early/late in the day (red-orange bias to sky light) and "indoor" stuff, especially under the floodlights. As I recall 1933 was on the cusp of the shift from the "ortho" films - "red-blind" - and the "modern" Panchro stuff. I recall seeing ads for film in the late Fifties that touted how the "new" B&W films gave such "faithful rendition" of ALL the colors in a scene - which baffled a young boy like me... but... there aren't any colors in the pcture!
Seriously - it wasn't until the late Sixties that Hollywood directors & cameramen were finally lured away from the (garish and inaccurate) colors of film stock until then. Color film was reserved for either musicals & "period" costume dramas (lots of garish colors) or outdoorsy stuff where they could count on a generically blue sky, green trees & brown dirt - which is why those flicks were either Westerns or big screen Epics. Check out Rollei's Ortho offering - Efke had a great one, now gone. Great for a retro-feel if you're into it.-alfredian
