Digital BW, The Print

I will look forward to seeing them. I too have the same sense that you get about the deviations of readings for the different spectros. From what I can learn, it appears that a fair number of the recent and currently available instruments might actually plug in assumed values from about 420nm on down using a variety of proprietary undocumented magic numbers.
I'm personally very interested in the extended readings you may have.The instruments I currently use are all from x-rite and are all intentionally limited to the 400-700nm range. I'd like to get around that limitation at some point and have some plans to do so.

Regards,
Duane
