PESO: My First Lightroom Rendering with question

[Christine Aguila]

Hi Everyone:

I just downloaded a trial version of Lightroom and started fooling around 
with a Memphis shot.  I kind of like what I ended up with, but I have no 
idea how I got there.  I really just started moving sliders around.  I have 
a feeling I might be out another 300 bucks soon.

Anyway, here's the question:  do you primarily shoot PEFs or DNGs since 
Lightroom does PEFs?  Any preferences or does it even matter.  This shot is 
a DNG.
