Quote: While I'm sure the people advocating colour reversal material are getting the results they want with it, you might well find both colour and monochrome negative film is easier to use because it has a greater latitude.
I agree. Neg film is a lot more forgiving and you need that with this sort of photography where you might face reciprocity failure mixed with very start contrasts, so that exposure tends to be distictly hit and miss. Slide film has to be bang on. Neg can be at least a stop under to 2+ stops over exposed and still be usable. With slide you will need to bracket like crazy.
