Thank you for all of the replies. I understand the difference between RAW And JPEG files. I wanted to know what happens to the original, camera generated JPEG after edits are applied in Nitro. From what everyone has said, those edits in Nitro are just added to camera generated JPEG, when they are saved. Back in Photos, the JPEG displayed contains the Nitro edits on top of the camera generated JPEG. If Photos is set to “Use JPEG as Original”, and I select to “revert to original”, now the JPEG should be the original camera generated JPEG, now without the Nitro edits added. Is this correct?
Thanks for all the help. I might be over thinking this.
