You could build your image processing style from scratch – go to the history panel and choose the original state, then compress the stack. Then go to the Base Curve and apply the Sony curve preset. You could also change your demosaicing to AMaZE, do the auto CA removal, switch on lens corrections, set up your sharpening and output profile. Then make a style out of it in the history panel. You can apply that style to all your selected photos in the Lighttable view.
It’s best to establish your basic style on the basis of good studio photos for your camera – you’ll find them at DPReview or Imaging Resource websites. It’s especially important if you want to modify the Base Curve to suit your purpose.
