Ron , It makes everything simple and cheap. Two dichroic filters cost 2 inches diameter 50 dollar , 1 inch diameter 35 dollars. Is it that simple to get the look of old films ? Is there a modern photographer of this technology ? It is huge different from todays japanese cameras and modern films. I am thankful to find my rollei 35 s with sonnar and old summitar experience showed me these lenses are very capable to produce rich colors but at dim light. This is two color technicolor. Negative of this picture is green heavy at skin colors .
