Best film scanning services in Paris and New York?

Hi folks,

It's been a few years since I have been here, and it's nice to come back and realize what a resource this forum continues to be.

I have a photographer friend in Paris who is looking for high quality scanning/retouching services (drum, Scitex, perhaps Imacon, etc.) in Paris and New York for all formats, mostly 35mm chrome, but all the way up to 4x5 neg in color and b+w. The output is mostly for books she publishes. Paris is highly preferable, but she can travel to NY.

Given that I work only with Digital Fusion in LA, where I am very happy for my own work, I realized that I am out of the loop on where else one might go.

Any advice would be greatly appreciated.

Happy shooting and all the rest to you,

Claudio
