I bought this almost mint condition 6x9 KW Etui camera half year ago.
It comes with 6x9 film adapter , unfortunately I don't have film holders.
This one is top model with 12 cm 4.5 Zeiss Tessar lens. Finally last weekend I shoot first direct positive with it. Those are first pictures to try find correct exposure with my lights ( 3 slightly longer Mississippi's at f4.5) .
I also find reason why my direct aren't that contrasty . I am using Ikea plastic red table light with 25 watt bulb inside. While cutting paper for 6x9 I figured out that its not safest light
. I am developing this paper ( bathroom ) about 1,5 meter from light first minute diffuse light with my back and after image is appear I am checkin it very close to light. It didn't give me fog and pictures taking some light showing more middle tones.
