A simple tutorial on applying individual per camera default settings applied during import in Adobe Lightroom and Adobe Camera Raw. These Camera Defaults are saved out with whatever settings you apply in the develop module. Upon import Lightroom then applies this preset to the specific camera serial number importing the raws with theses settings already applied as a base.
This is the reason why it is best to limit the corrections to the non subjective controls such as camera lens corrections, sharpening ( input related) and process settings. Color controls exposure etc. are variables, thus not usually applied as a base for all incoming images from that camera.
