Some background on the Durst negative holder called Laraneg. It uses two 10x10 glass plates, with the top one being AN glass. There is no glassless option, because the equivalent of a hair blow dryer forces cooling air on the glass during exposure. The system is designed so all smaller film formats will be placed in the center of the glass and masked from below with a series of cutout frames called HOMASKSET. The HOMASKSET mask is held below the lower glass by some clips.
Of course, these masks are near impossible to find. However, I found one!! I'll use it to make the other sizes that I need, now that I see exactly how thick it is and its exact dimensions.
