ON1 saving image as the original file type



  • Don Maclean

    You are not saving the image, just the changes you have made to the image. The original RAWs are never touched.

    If you wish to save in another format use the Export tab where the changes will be applied before export.

    What exactly do you mean by "saved"? Photo RAW does not have a save function. Edits are written to the .on1 sidecar file and to an internal database to save them but the RAW file does not get overwritten. That's what is meant by "non-destructive editing."

    The .onphoto file type is ON1's proprietary format for Layered RAW files. HDR's, Panoramas, and images where multiple Layers have been used are saved in the .onphoto format. If none of those features of the program were used; i.e.; a simple edit containing only Effects, Local Adjustements, and Develop adjustments will not cause the creation of an .onphoto file.

    I know there is no As Saved, if you want me to say I click Done.

    I have edited 2 images, both NEF.

    the 1st image I just apply a Preset, and click DONE.

    It is saved as a the original NEF with the edits.

    2nd image I mask out the background and put  a FILL Colour Layer beneath it, and click DONE

    It is saved as an ON1 Photo with the original NEF untouched.

    My question is, why does one save as an NEF Format and the other as a ON1 Photo Format

  • Brian Lawson Community moderator

    When you added the Color Fill Layer you added a 2nd Layer. That requires the creation of an .onphoto file to hold the separate Layers with their RAW data.

    The 1st image where you only applied a Preset doesn't need the .onphoto file as there is only 1 Layer.

    Take a look at the Layers panel for each photo and you'll see the difference.

    I asked about your use of 'save' because it doesn't tell me what you actually did. Clicking the Done button is a more precise and meaningful answer to someone trying to understand and draw a mental picture of what you see in front of your own eyes.

    I can see what your saying, it's just that I never use Presets and thought I'd try one.

    I've been editing photos for 62 years now, well before digital, I taught photography for some years and understand photo editing, however, I prefer to make all my own adjustments to an image.

    Thanks for your help.

    I generally do not use Presets that come with the program or which can be downloaded and installed either. I do have a few that I created which I do use just because I use the same steps as saved in them repeatedly. And, they are beginning points, not polishing edits.

    If you are still not clear about the editing concept, I would suggest copying any photo in Photo Raw, to give you a test file. Now select the test file and go to Edit. Make any changes that you like to the test photo, preset, develop, effects... anything. No need to spend lots of time on the edit, but make sure you apply something that is very obviously different to the original. Click on Done. Now open the test file in different photo software or a photo viewer (on Windows, the Photos app would be ideal). You will then see that the changes you made are not visible. Instead, you will be looking at the original test file that was created when you did the copy. 

    This proves that the original files are never edited, and the edit details are only saved in the associated on1 file. As Don Maclean stated, the edits only become embedded when the file is exported, but even then a new file is created, still leaving the original untouched.

    Hope this helps.
