I think I'm the only one here using PS elements, so my way is alittle different, but hey, it might help you/someone
I usually create a adjustment layer- levels, and tweak them up a little, this gives them a fabulous 'from inside' kind of light. then I make this layer 'screen' (yes I know its just 'white out-ed' your picture...bear with me!) adjust this downabit to say 70% -50% depending on picture, merge this layer down. select adjust lighting, dip your brightness slightly (to bring back your darker colours) and always slide your contrast up some
to make those colours pop! hope thats of some help to someone !
