... Actually to compensate for the light loss typical of a smaller negative carrier opening. FYI - I disassembled the 2.25" x 2.75" D5 mixing chamber. Yes, it covers only 2.75" square. Interesting box. It is made simply of five pieces of flyweight white styrofoam and translucent plastic on the negative side. Light enters at the side through a short square mirror-sided corridor. That makes for really diffuse, cold illumination.

What you have is a "DB" mixing box for MF negatives.
The "DD" mixing box is a 5" version and is provided standard with the Lamp house.(For 4x5) , "jjs" wrote: "Gregory Blank" wrote in message ...

I said I had one of each, and I disassembled the MF box because it is expendable and I wanted to see what they are made of. Turns out the problem was deteriorated foam around the LF box's exit that fell into the path. Fixed.

I think mine is still white but I think they need to be relined over time. Nick
