filmscanners: Scanner calibration for old dyes!

[Andrea de Polo <andrea@alinari.it>]

Hello,

I have my Microtek Artixscan 4000T calibrated using the Kodak IT8 
slide and my chromes look ok; The problem is when I have to scan very 
old slides, dated back in the 1940' and 1950; the have major color 
deterioration; by apply the current ICC profile I will get very bad 
color balanced images; this is because the dyes and colors of the 
current target from Kodak, Agfa, etc, are very different from the 
images dated back in the 1940 .......

How shall I than calibrated and match my color for those kind of old 
images, considering the fact that I do not want really to provide 
accurate color restoration, BUT scan and maintain the color hue and 
color value of those old images close to as they are today???

TIA; Andrea
