Left the sandwich of scannerglass/film/polyester and lighter fluid in between all for 24 hours on the scanner. First there's hardly any fluid evaporated, didn't notice discoloring either. Skin fat could be the slight haze that is left on the film, could also be that the lighter fluid has a lower grade of distillation than the pro mounting fluids. If the film will be used for scans only there isn't a problem. Wet mounting has more advantages than just getting the film flat, it fills all the scratches, gives a better optical path through the layers and when care is taken should give less dust as a glass mounted film. On skin fat: in the old days the darkroom man would rub a finger along the side of his nose and apply it on the negative to fill the scratches, there's no need to that with wet mounting. Wonder whether that ecologically correct advice attracts more flames. Ernst
