Hi Jon,
I think you are going to have several problems with profiling a photo
lab. The first is finding out if they use a laser printer that images
on silver halide photo print material or if they use a half-tone printer
to produce the prints. The next problem is that most photo lab software
has automatic color correction based on the content and lighting that
you used. The software tries to automatically adjust to produce
pleasing color. The automatic color balance that is done will mean that
the color adjustment done to a test file may not be the same as a
typical photo that you send to them.
I am told that some labs can turn off this automatic adjustment.

How would one make a profile of the output from a photo lab? My first
instinct would be to send an ECI or IT8 target to the lab and make a printer
profile of the print that comes back but the photos must be in RGB going to
the lab. What would be the proper procedure for this?
