Hi Kai,

Interesting website and all respect for the work you did , just one
thing:
are the color(s) still the same at this moment compared to the moment
you scanned them?
In my experience, toning was exciting and after some time disappointing
due to the fact that the toning was far from permanent.
Cheers,
Henk
