    What does your edit RAW image look like with proof profiling turned on? Assuming you have selected an Output recipe that matches you Export settings for the jpg.

    Is the application you are using for viewing the jpg colour managed?

    Bear in mind that your ARW edit is likely being viewed on a screen that has potential to display a wider colour depth (more colours bit maybe not for all colours equally) then the jpg might use after compression to an 8bit file. In addition the jpg size is somewhat less than the original edit size in terms of the dimensions of the image displayed. That means there are fewer pixels available to make the image and the combination of jpg compression of colours (to make the file as small as possible) and size (some pixels will have been discarded) can introduce quite significant changes to the way it appears.

    This is especially true when small details, for example the star points, are small even before starting compression and, perhaps, applying noise reduction during export to the smaller file.

    Just a few factors of many variables in the steps if the process.

    I'll leave it to any night sky experts in the forum to suggest options for optimising night shot workflows.

    Hey,

    I'm not sure what you mean by output recipe and proof profiling.

    I am using default windows 10 image viewer.

    I'm not worried about this particular picture, it was just a test after all and the iso is way too high. I'm just concerned that all my images will look different. I don't want to learn how to use capure one, only to find out it is not working for me. What settings should I use to avoid this?

    Discovering these features would probably be a useful thing to do.

    There will be some Help file entries related to these features and probably some Tutorial videos but you might like to to take a look at the this Webinar video as well.

    https://learn.captureone.com/webinars/o ... or-export/

    IN the text below the video area you will find a list of some of the specific topics covered with timing information that allows one to go straight to the section of interest.

    I think the point is that the Windows 10 image viewer is not colour-managed, and people often complain that it makes images look different from what they expected. See this for example.

    I am not a Windows user myself, but there have been a lot of threads on here about this issue from Windows users. You might try searching this forum to see what people recommend as a better way of viewing exported images.

    Hi,

    Why do my pictures look different when being exported? I am very new to it, am I missing something here? I know it's not very pretty but you can cleary see the difference here:

    Couple of things to try.

    Take a look at this video it should explain a few issues. In particular look at 14min where it shows you how to soft proof - show how the output will look for the chosen recipe. With soft proof selected for your chosen recipe (must be ticked and selected) edit your image to taste.

    Is your monitor wide gamut?

    If it is Windows photo viewer will not show the output correctly as it is not colour managed. Use Faststone viewer (https://www.faststone.org/FSViewerDetail.htm) and turn on use colour management and auto detect and use monitor profile in Settings - CMS

    Further to Ian's comment:

    I don't have Win 10 but a Google search suggests that the regular Win Viewer can be colour managed BUT the Win 10 "Photos" viewer is NOT colour managed. If so that seems like a strange decision from Microsoft.

    Regardless of that one of the more obvious problems with Astro photography is that the stars stand out against a dark sky but are in effect very small point light sources using very few pixels.

    If one compresses the image for sizing or scaling purposes some of those few pixels may need to be discarded - to the point where the star almost disappears (whether on screen or printed makes little difference) when we view the image.

    On the other hand if the processing algorithms decide to retain most of the available pixels an individual star may appear larger than it did - especially if the stars around it have been made less visible being smaller.

    Add in the colour changes that may well lose many of the subtle changes of colour and tend to make lighter tones stand out more in high contrast situations as far as our eyes can interpret things ... then it all gets a bit challenging to deal with if you are seeking absolute accuracy despite the need to use somewhat different settings during processing compared to output.


    Those comments are general comments about making comparisons rather than specific comments about comparing an on-screen RAW file editing session in C1 with a view of an output file in a different application but are, nevertheless, worth remembering when making comparisons.

    HTH.

    I've noticed the same thing and I'm on Windows 10. What I believe is happening is that there is more contrast in the exported jpeg file. I've noticed the same in another application that I use (On1 Photo RAW 2019).

    At first, I thought it was because I was shooting in Adobe RGB and exporting out into SRGB, causing the gamut (Color range) to compress. So today, I went and shot in SRGB. At the end of the day, it was the same issue. So I started decreasing the contrast in my photo a little to get the desired look in my exported JPEG. Not the desired workflow I would like. (Adjust, export, review.... repeatedly).

    If anyone else on Windows 10 can test and confirm that the exported jpeg has more contrast, giving the darker look. Please confirm.

    I've just compared a TIF and a JPEG (90 Quality).

    Using the same parameters (8-bit Adobe RGB, 100%) they look exactly alike (even the histogram is pretty much the same).

    Make sure you use the exact same settings in the "Adjustments" register of the Process Recipe.

    "No Output Sharpening" is not the same as "Disable All" by the way.

    Are you starting with a "RAW" file from the camera or a jpg?

    If RAW the colour space you use in the camera (sRGB or Adobe RGB) is not important. All it would be is control the embedded preview file in the RAW file not the the data in the file. That will be reinterpreted by the RAW converter program using a much larger colour space than either of the in camera ranges.

    If you are working with the jpg the nuances of the chosen colour space will be embedded in the file as a starting point and so slightly restrict some of the colour interpretations that could be made in certain parts of the possible colour ranges. However what you are seeing on output will be influenced by many other factors depending on the medium you are using for viewing the results. Also the medium used when editing - for example how bright you screen is.

    HTH.
