Justin.
the same way you do with raw images.
Note my comments are based on using PSP X2 other programs may differ in command name but not function
to get instant fix of WB issues, you select
ADJUST the
Color Balance
this lets you pick a point that is any shade of grey from pure black to pure wight and it adjsuts the color levels to make that the color
you can then adjust color temperature to make it warmer or cooler to your liking
for exposure it is simply adjusting the histogram curve like in raw.
the only difference is that you are , as raw pruists will point out, working only on the origonal jpeg subset of the full 12 bit data, therefore if you have a big adjustment to make, you may not be able to do it as well, but as I said, in my opinion, of you are that far off, you really blew the shot.
