Thanks to everyone who responded. I'm going to print some of the Kodak Ultra Color 100 negs this weekend, then bring my version and the lab's version back to the lab. We'll see what they have to say.
I like the lab a lot. I've never had quality control problems with them although I've had problems with many of the so called NYC prolabs, such as Duggal, ColorEdge and Modern Age. They actually don't machine process the negs they only use the Agfa machine to scan the negs and produce the prints.
