A couple of questions about transfer functions.

Once a transfer function is set in the page setup dialog box, does it get
saved with the file, or does it stay active for all other prints as well.

One disadvantage I see to a transfer function is that it is buried away on a
second page the Page Setup window, so one may forget if it is on or off. In
light of that, is it in anyway preferable to a luminosity adjustment layer
curve? I like the idea of an adjustment layer because of it's visibility,
and with PS6 we can group such a layer with one of Paul's tone curves as a
layer set. Such a set can be aptly named, and easily monitored, in a way I
find difficult with transfer curves.

I guess it's really moot in the end as a transfer curve can be loaded as an
adjustment layer curve, and vice versa. So people could apply the same curve
through either method. I just wonder what is the preference for the transfer
approach?
