Flourescence (of the object) did occur to me (and polarisation). However
since it's in the visible spectrum, and works with tranny, neg materials
shouldn't have any problems - far fewer, in fact, due to the wider subject
brightness range. The difficulty comes in reconstructing what was seen as a
visible image through the eyepiece, and trying to derive a scanning
workflow to achieve this seems to be the sole problem.

IOW you could have dispensed with your daylight tubes and just used rotten
domestic ones + colour neg, provided you were prepared to be driven
slightly mad in Photoshop ;-)
