Hi, Stupid question, but the wrong answer could cause your problem:
Is your polarizer (the one on the lens) a "Circular Polarizer"? If not, that would be capable of causing the problem. It does sound more like it is subject tonality that is causing the problem since it seems like you probably want an overall light grey on the slide. Unless you want darker grey slides, you should compensate. Mike Miha Valencic wrote: > > Gerard, > > I'm pretty confident, that it must be the subject. Reciprocity failure is > not the case.
