There are some other references to this on the 'net but I thought I'd make my own anyway so I can check out what certain filters do.

Upper colour bar is a standard 600D response to a torch I have. The three mono lines below that are the RGB split out. Below that is a 450D with the removable filters removed, thus passing IR and maybe some UV too.
The amplitude isn't calibrated to anything but should be relative within a colour channel, when it's not clipping anyway. I need some way to work out what wavelength each point is...
