Is the Photoshop Editing Process Destructive to RAW Files
My workflow is to load my RAW NEF (Nikon Camera) images into Lightroom. During editing I make basic adjustments (not cropping) in the Lightroom Develop Module and then I export the image to Photoshop for more extensive editing including cropping. When I am finished editing in Photoshop the file is saved back to Lightroom as a psd file. My question is whether or not the original RAW NEF file is changed by either Lightroom or Photoshop? At the present time I back up my work folders which include the psd files for those images that I have edited as well as all of the RAW NEF files from a particular shoot. If the RAW files are never modified by the editing process described above I am comfortable that my backup process is adequate. If I were to find that the RAW NEF files are impacted then I would have to consider the need to create 2 additional backup files for the original RAW NEF files.
