sandro Posted August 14, 2015 Share #1 Posted August 14, 2015 Advertisement (gone after registration) In another thread I mentioned a curious old A36 filter. Now I noticed that I have two different A36 (screw) blue filters. One of them is marked Leitz New York and "pf", it is of a lighter blue color than the other one. So did two kinds of blue filter exist, in varying degrees of blue? Lex Quote Link to post Share on other sites More sharing options...
Advertisement Posted August 14, 2015 Posted August 14, 2015 Hi sandro, Take a look here A36 blue filter. I'm sure you'll find what you were looking for!
Orient XI Posted August 17, 2015 Share #2 Posted August 17, 2015 Leitz (Wetzlar) made A36 blue filters BOCOO/13020 from 1955. Leitz (New York) made Kodachrome conversion filters from 1949; there is blue FP type A36 from 1957 — FPKELM/13071 — which could be used to convert CLEAR flashbulbs' light to daylight. This was solved more simply by coating the flash bulb's glass envelope with a blue lacquer. If the other filter was a conversion filter to enable daylight film to be used with tungsten lighting then they should be of different densities.

sandro Posted August 19, 2015 Author Share #3 Posted August 19, 2015 My filter is marked PF, not FP. I took some photos, perhaps they can help. Thanks, Lex Welcome, dear visitor!

new2leica Posted August 20, 2015 Share #4 Posted August 20, 2015 Theres a blue filter for black&white film, used to enhance fog and haze. And there are blue filters for color film, used when shooting daylight-balanced film indoors without a flash. The PF is photoflood I think. Old time version of an 80B.

sandro Posted August 20, 2015 Author Share #5 Posted August 20, 2015 That is a very interesting option that I didn't yet consider. For my black & white photography is use several filters (I use analog Leica M camera's), like yellow, green, orange and red. The more pale kind of blue of the PF filter on the right might indeed be a color conversion filter. Thanks! Lex Quote Link to post Share on other sites More sharing options...
