Using 2 Levels Adjustments together

You go first, I can wait

In response to a reader's question, here's a tip on using Levels adjustments to correct exposure issues.

Perform the first steps of the workflow, open the image and correct for focus. If there is a colour cast or haze, use a Curves adjustment to correct it.

In addressing the exposure problems, try this:

Add a "blank" Levels adjustment and set the Blending Mode to Multiply.
Then add a second Levels adjustment and make your corrections there.
You can Group your adjustments if you choose by selecting the adjustment layers and choosing New Group from Layers.

This technique works from CS3 back to at least version 5. I know that I'll get a few responses telling me at this image can be corrected faster using ACR ("... just kick up the exposure a stop and a quarter ..."). I realise that. Unfortunately, we are still addressing the fact that many agencies are having funding issues and can't keep up wit the cost of software updates.
