This don't work when you change a part of your equipment. Or because the value<br>
|
||
returned by the scanner can be depending of the lamp use.<br>
|
||
This can't work with slides scanner too!<br>

Could I suggest another possibility (may be)?<br>
|
||
If someone known the value of the Kodak color and B&W chart (they are not<br>
|
||
expensive) may be it is possible to have a printout of it and some variant.<br>
|
||
we look the variant which is closer to the reference chart and obtain the<br>
|
||
value of correction to be applyied.<br>
|
||
May be the the it8 reflect chart (You can find one on the web, I'll put<br>
|
||
<a href="http://www.regix.com/regisr/files/it8ref.jpeg">http://www.regix.com/regisr/files/it8ref.jpeg</a> if you want to see it) can help<br>
|
||
the process of calibration.<br>
