I'm interested in recommendations for service bureaus that can produce digital negatives from tif files prepared in Photoshop.

I'm in the New York metro area, but don't mind using a bureau outside my area if it's a good one.

Thank you!

P.S. I'm sure there are folks who would encourage me to produce my own digital negatives - no need to go there; i know all about that. Right now I just have a particular need for a service bureau.

Thanks again.
