[Radiance-general] Scanner Calibration w/ Macbethcal

[Marcus Jacobs]

Dear Group

I have recently attempted to calibrate my scanner using a Macbeth Color 
Chart in conjunction with Radiance's macbethcal. I have run into some issues 
with 1-3 of my colors (depending on the scanner settings) being out of gamut 
from reviewing by debug.pic. What I would like to know is if there is any 
way to rectify this situation? If not, how concerned should I be with this? 
I wish to use calibrated colors in order to match some of the paint color 
swatches that are available at many hardware stores for use in my 
renderings.  Regarding my scanner, I am using an Epson Perfection 2480. Its 
a great scanner and therefore I wish not to have to replace it in order to 
experiment in finding another scanner that will keep the colors within 
gamut. As far as my scanner settings, I choose no auto exposure (selecting 
this option too leaves some colors out of gamut) and no color correction. 
Any thoughts or ideas?

Thanks

Marcus
