Transmissive Profiling, Special Considerations

transmissive fusion capture should be done with careful even fielding (lcc), consistent gating, tight masking, and very low ambient light otherwise the improvement in color/tone accuracy provided by fusion will be overwhelmed by the decrease in color/tone accuracy caused by these issues even fielding (lcc) – mapping the light the camera sees in the capture area, which is the combination of light loss due to lens vignette, uneven illumination, and gating between the illumination and the subject even fielding should ideally be done with a thin semi transparent plexiglass at the film plane, acting as a surrogate for the subject matter to be digitized masking – blocking undesired light from the capture area from reaching the camera masking should be done at the film plane, or as close to it as possible for example with a dt magnetic film carrier the carrier itself asks as the primary method of masking be careful with masking that is above the film plane as it may reflect some light back into the film (even if it is black) be careful not to use gating (baffling below) for masking; this can lead to poor even fielding results, especially if it is moved between even fielding (lcc) and capture gating – reducing the area of the transmissive light being used, preventing light from those areas from reaching the film importantly gating should not change between capture of the materials and capture of the even fielding
