in the case of cameras a
profile is environment specific, in or out of the studio. This means you
can have 1 really great 5000K general profile for day or strobe (a tough
one). Or a specific profile for each environment (better).
I would have to disagree with this entirely. The difference between shooting
under 5000k studio light and shooting outdoors is gray balance. By gray
balancing for each lighting condition you are 3relinearizing2 the camera to
function with your one profile. Profiling scenes is problematic because of
outside influences (color) reflected onto the target or uneven lighting. A
good profile requires the target be lit with great care so the comparison
between data and patches is not subject to scene specific shifts. A great
many of the problems being reported about profiles not working are most
likely related to the care in which they are made. Profiling scenes is a
silly idea that should stop being promoted. All it does is make for bad
results and does nothing to further the craft of building and using
profiles.
