Color shift from preview to captured image

m_art_in
I'm currently evaluating Capture One and am quite impressed by the many tools it has. My main headache is as follows:

I have a Nikon camera tethered to the laptop, the camera has a manual white balance. When I capture an image, it shows up with more color and contrast, plus a slight shift in colors (left side shows the captured image, left side the live view):



Is there a way to make the live view more WYSIWYG, as I am doing color critical work?

Bonus question: Is there a way to pick a color-balance while in live view?

Equipment used: Nikon D850 (newest firmware), Mac OS 10.13.4, Capture One 11.1.1

    The captured image will show with a default colour profile for the camera.

    If you are not happy with that profile you can change the default to be something else.

    The camera display is, presumably, offering a version of the colours that it would process out to a jpg file according to its internal settings.

    With a RAW file (NEF) you can, of course, change the white balance to be whatever you want after the fact - the in-camera values are a guide of sorts but not in any way final for a RAW file.

    If colour accuracy is important are you already working with a fully colour managed setup?

    Hi Grant,

    Thank you for your speedy reply.

    Looks like my question boils down to this: What do I have to do so that the colors from the live view window match those of the subsequently captured image. I want to be able to do a manual white-balance in the camera, and then be able to judge color accuracy (not 100%, but that would be enough).

    I see that an automatic ICC profile is assigned (for the Nikon D850) - but I do not see how I can bypass that.

    Ok, I found the way to apply a "no color correction" profile. But there is still a shift, though more subtle, in colors:



    In the manual I read:

    > Capture One provides accurate color by reading the camera-generated RAW information, file header and settings file.

    How can I ensure that the manual white balance from the camera is read by Phase One, and no further processing applied?

    Well, you can edit a representative image to make it more like the camera's interpretation and then save the resulting "style" or a set of pre-sets (Pre-set is one per tool, a style is a collection of pre-sets). Then apply the Style to the images as you shoot them as the camera's default Profile adjustments rather then the Capture One generated default settings.

    To see what you might need to change have a look in your camera settings to see what values for "styles" (or some such description) are set in camera and affecting the jpg output - which is also the basis for what you see on the camera's screen though how accurate that is in a colour sense I have no idea. It's relatively low resolution so perhaps not that accurate for many colours.

    I'm guessing from your questions that my question about whether you have a fully colour managed workflow may indicate a "No" answer. It's probably worth re-iterating that what you see on the back of the camera is an interpretation.

    Personally, thinking about my cameras, colour accuracy requirements would not in any way rely on what the camera screen could show. Some very high end cameras - the Phase Medium Format backs for example - may offer extremely close colour accuracy - but the average camera is unlikely to do so. It will just give you another interpretation.

    But there are people far more qualifies than I am to discuss colour accuracy and how to achieve it so I'll let some of them offer their vastly better guidance.

    ETA. Having seen your followup post - you can't. There is no certainty that the WB settings the camera uses will give precisely the same results in another colour processing engine. Re-do the WB assessment with a reference target on the files as shot, not bu reference to the camera's settings (other than, perhaps, as a general guide to get you somewhere close to the values to use.)

    Hi,

    First, you should know that the jpeg OOC provided by your camera might differ from the image displayed by C1, as the algorithms used by the camera and C1 are different. The C1 interpretation is very likely to be different then.
    Second, there was, on an other (French) forum, a comparative studies of the WB temperatures read by various softwares, and it appeared that C1 was the better in transferring the WB value from the camera to its WB tool. Anyway, I think that, most often, the WB should be adjusted when processing, the best solution being a neutral target intentionally or unintentionally set into the scene. But you know that.
