How does one save their RAW adjustments (in the development persona) prior to compiling it into the photo persona? In other words I’d like to save my adjustments and updates to a RAW file i.e. lens distortion, detail refinement and noise reduction et al to a file so that if I require to return to that RAW file to make further adjustments I don’t have to reinvent the wheel. This scenario also applies to photo’s that were taken at the same time and require the identical processing.
