Adjustment layers, with screening and multiplying, are a far better way

don't forget there's a dodge and burn tool (o) for the quick and dirty 
method. select the tool, select the brush size and select tonal range  
and exposure. It can be applied to individual channels and layers much 
like the methods already describe previously.
