Will adjustments made in Picture Styles have any effect on images exposed in Camera Raw, such as Saturation or Sharpening or only for jpg's? Thanks for your help.

If you are shooting Raw, in-camera picture styles will not have any effect on your Raw file you import into your computer (if you use Lightroom - I believe DPP uses in-camera JPG settings but I'm not sure as I dont use it), however in-camera picture styles will affect your histogram & the review image you see on the camera's LCD.

DPP will apply those parameters to what it initially shows you even for a raw file.
