I've just done this exercise to try and get my head around the camera response. At the moment I'm not getting a consistent camera response curve from different spectra (so I have more learning to do ) though I expect to get a handle on that as I learn.
But I think I'm missing something... I think I should be able to save the camera response curve and use it on other spectra, shouldn't I? How do I do that? Each Time I try I get another copy of the raw spectrum, not the camera response curve...

I had the same problem with saving the response curve. The .spc files will only save 4 graphs.
I display the camera response curve that you want to save and then rename it as the 2nd reference graph. There is a way to do this in the "edit" menu. (I will look up the correct button when I get home as I don't have the program here at work.)
The other option is to save the response curve as a .dat file.
You can then open up the file you want to calibrate as well as the response curve and using the "divide" function correct the unknown graph.
