I know there are various methods of correcting poor exposures PP, but after a search on google i came across this tutorial:

It seems to have an advantage over raising curves/ levels etc in that it doesn't blow out the highlights. I am not sure if there is much difference in it and Highlight/Shadows tool.
I tried this last night on a night shot of a lit building and on a backlit daylit portrait taken outside (foreground very dark).
I was impressed with the outcome, and the fact that no matter how much i turned up the brightness using this method, it only brightened the dark to light areas proprtionally, ensuring no blown highlights.
Are there any other similar methods which people use which also provide good results??
