Gast Hello, I have an Orwo Dukafilter in my collection, number 116, yellow-green. What kind of material is it suitable for? It gives off a very dim light with a 15-watt bulb; you can really only see where the light is hanging. Best regards, Marwan
uworischki The Orwo No. 116 filter is suitable for black-and-white papers with a fixed gradient, PE or baryta.
Gast Thanks for the reply. I’ve got another one with the number 166 – greenish-yellow and white – does anyone know anything about it??? Thanks in advance! Regards, Marwan
FoxTalbot Hello, Have a look here – you'll find (almost?) all of them at http://www.grosskabinett.de/photo/Labor/dukafilter.php
