Why are my RAW images pre-corrected?

    I can't tell if you're referring to Low res vs Hi res previews or if the default Camera profile is being applied automatically. If you want a definite starting point for all of your photos, create a preset with the Camera Profile set to Linear RAW and apply it to every photo that you import. That should start every photo with nothing applied to it.

    For unedited photos it sounds as though what you first see is the camera generated JPG that is embedded in a RAW file, then On1 loads the actual RAW data without corrections being applied.

    If you are on a Mac you are able to open the folder containing the images and view this as icons. As far as I know this will display these built-in JPGs, so you can check whether these are also oversaturated. If so it could be down to camera settings, any styles that are set are used to generate the JPG previews even if shooting RAW only. I am not sure if this works on Windows as I don't think this has the same ability to look at RAW files without adding extra software.

    After editing you should see a preview of the edited image, this is not as high a resolution as when the RAW image is displayed. I don't see a major difference in image between the initial preview and the fully loaded RAW file, more an increase in sharpness as the full image is loaded.

    The time taken to replace the preview by the edited image depends on how many filters, local adjustments etc have been applied, and how much masking was done. As On1 is non-destructive when it loads an edited image it needs to apply all these again so that you are then able to change settings etc. This time is increased if you have enabled NoNoise. A second or two to load an image compares very well with the time that Photoshop takes to open a PSD file with similar number of adjustments and masks.

    When you say you see the oversaturated image again when you go back to the image have you applied any edits to this image? If not then it is still starting with the built-in preview since no changes have been made, so that is probably what is in the cache.

    The preferences panel related to cache settings is a bit confusing. The size relates to the memory based cache. The size of the disc cache generated to hold previews generated when folders are catalogued doesn't have a size limit, mine is up to 191 Gbytes.

    Thanks guys,

    Not sure if that is what is happening here.

    Rick Sammartino What do you mean by "I can't tell if you're referring to Low res vs Hi res previews"

    I have my settings set to either standard or highres previews on import. But I will also set that preset up for my next import to see if that works.

    David Tillett Thanks for that detailed reply. I'm starting to understand a little better now. But I still think what's going on is a bit weird, because this oversaturated version of the image does not look like an adjusted version of the original image. It looks more like an adjusted version of my edits. Look at these screen shots:

    1 - The very second I full screen the image - oversaturated, but appears to be oversaturation ON TOP of my edits.

    2 - After waiting about 1-2 seconds - the image with my edits

    3 - The original RAW image (ie Preview off)

    4 - The OSX preview of the RAW file - Would this be the embedded Jpeg? Because this is definitely not the oversaturated preview I am getting. My camera picture profile is set to neutral on the Canon 6D.

    One thing to keep in mind is that by default Photo RAW is applying a Camera Profile to all your photos. This is just a LUT that is applied before any other processing you might do. The default profile, Standard, does tend to make the image brighter, more saturated, and contrasty. The Linear RAW profile tells the program to not use any LUT so you see the actual exposure.

    Aaaah, ok. Thanks for clarifying that. So you think that is is what is happeing? I will re-import these as a test and see if it happens. Thanks

    Without seeing one of your files for myself, it's hard to say. I just wanted to be sure you understood that portion of the program.

    It shouldn't be necessary to re-import them. Just open one up in the Editor and change only the Camera Profile then return to the Browser and see what affect it has.

    If the version that appears after a few seconds matches what you are expecting when viewing your edited image then at least no issues with edits changing. So comes down to an issue with the preview associated with the edited image. It looks as though this is a more saturated version of your image and I am at a loss as to why this is, I see an improvement in image quality, a sort of crispness from increased resolution, when display switches from preview to fully loaded, but I am not seeing a major change in saturation.

    If you select one of images that is giving problems in Grid view and then look at the Photo menu drop down you should see a Refresh Preview option, try clicking this and see if the new Preview is any better.

    Are the images in a Catalogued Folder? If so what preview quality did you select? I use Standard and just wonder if choosing Medium or Minimal might result in a lower quality preview which might explain the increased saturation.

    The OSX version does look as though it has had some minor processing done compared to basic RAW image, so I think that implies that this is the built-in JPG, and that is not oversaturated, so not a side effect of any camera setting.

    I think On1 is basically working as it should in that when browsing etc it loads the preview of the image first and then loads the full image in the background ready to edit or fully examine in Browse. Your issue seems to be down to the quality of the Previews.

    I suggest that you send a copy of the first two screen shots to support along with the original file and its side car  and see if they have any comments. The way I send such things to support is to use WeTransfer and upload the files to this, then send the link to support. The free uploads expire after a week, so there is some security in using this.

    If you do this and are happy to do so then you could post the link here then I, and I guess Brian, can see if we have the same issues on our systems.

    I am facing the same concern, The raw file we open with On1 doesn't apply the camera default setting, Anyways to fix this? All my camera bodies have the same issue, but I have notice that some photos are fine but when we have the good exposure photo. Some time my photo become dark around 1 stop of it RAW file and some are tent to over expose and give me highlight clip.
    I did try to check "Disable Base Correction on RAW Photo" but it seem no affect at all.

    Hope this can be fixed not a default behavior of On1NoNiose.

     

    Thanks.

    this is how it different from window explorer (raw preview) and preview on ON1 NoNoise 2022

    Windows Explorer is showing you the camera generated jpeg preview while Photo RAW is showing you the actual RAW file without any edits. The camera is making its own edits to generate the preview. Photo RAW's AI Match button in the Tone & Color panel should give you a close approximation of what you see from the camera.

    Thank you Brian Lawson for you explaination.
    Is there anyways to bring camera setting to On1 NoNiose RAW ?  Why I want it? Because when I export to DNG and using it with Photoshop all the setting are all gone. 
    It would be great to keep the camera setting and use it on On1 because. I personally, would love to see my photo look as close as it view on my camera back LCD.

    Thanks.

    That is what the AI Match button is for. It is supposed to emulate the camera settings. From page 120 of the User Guide, "The AI Match button uses artificial intelligence technology to automatically adjust the controls in the Tone panel to closely match your photo as you saw it on the back of your camera’s display."

    You can set up a Preset that incorporates just that button click then apply that Preset during the Import or, if you don't use Import, by selecting all of the photos in the folder and applying the Preset manually.
