Changing color temperature settings in PS7

[DamselDoc]

I recently noticed that when I use the raw converter I downloaded from Olympus in PS7, it gives me the option of adjusting the color temperature when I open the file. This was something that I really like when I was sampling CS2.
Is there any way to change color temperature in PS7 if you are not using the raw converter – say you are just working with tiff files? (I tried searching the help files in PS and old posts here and couldn’t find anything).
I want to use the tiff files because it lets me use layers and make adjustment that I think I lose when I open the raw files.

Any ideas?
Thanks,
