Title: RE: Any use for the D65 filter on the Spectrolino?
Hi Marco,
I haven't done a test yet with the D65 Viewing Light Source option checked but I will plan to do so since you've got me curious. I'll let you know what I find.

Steve,
In the message appended to your post, Brian Ashe (of Gretag Macbeth) points
out that one can select D65 from the "Viewing Light Source" pull-down menu
in ProfileMaker. I myself have not yet thought of making profiles using the
D65 menu choice in ProfileMaker, but I will start to explore that option
now, and to compare the results to those obtained using D50.
Just out of curiosity, and for the sake of your test's completeness for
Popular Photography, are you going to create a profile using the D65 light
source menu choice in ProfileMaker with an unfiltered Spectroscan? Please
let me know if you do. If the results were to come out very close to those
you obtained using the physical D65 filter, that would be very interesting.
Thank you.
