Can I have Nikon Capture NX open NEF files with NO processing?

Discussion in 'Nikon' started by Fred Garvin, Male Prostitute, May 14, 2007.

  1. I have found that when I open NEF files in Capture NX, the image appears
    for about a second and then its appearance changes (it gets darker and
    greener). How can I get Capture to open the file as TRULY raw so that ANY
    processing to the image is manually applied by me?

  3. You can't; *truly* raw, remember, is a mosaic of red, green, and blue
    pixels, not a full-color image. So nobody supports opening it that way.

    It is not actually processing the image. It is just that part of the
    image appears before Capture is done rendering it. When you initially
    see the image Capture has not finished reading and interpreting the
    file.

    If it's anything like the Browse window in PS, it's because Capture
    pulls in the thumbnail from the RAW file for quick display, and then,
    over time, replaces it with a more fully-processed version of the RAW
    data. In this case, the later image more accurately reflects the RAW
    data.

  7. Capture reads and uses all your in camera settings. Be sure all of these
    are set to off. Contrast, saturation, sharpening,etc.

    Isn't "fully-processed RAW" a contradiction in terms?

    Not really. Any rendition of a raw image is essentially a JPEG. The
    software has to interpret the data and turn it into a picture somehow.

    All software has to somehow read the position of a few electrons on
    your media and somehow interpret that to say, "Ah! light up a red pixel
    on the computer screen." That is what processing is. A digital image is
    not some latent image on a piece of film that can be seen directly. It
    is just a bunch of 1s and 0s that have to be processed to make an image
    appear on your screen. If you want to work with the data directly you
    have avoid an image editor entirely and use a hex or binary editor to
    change the individual bits.

    The image editor is going to look at those 1s and 0s and make a best
    guess of what the image is. It is going to try to determine the
    exposure, white balance, and everything else from what is stored in the
    data. Now, you can set Capture NX to use the same settings that the
    camera used, to automatically choose settings that it considers
    optimum, or to use settings of your choice. But it has to use some sort
    of setting or you will not have a viewable image at all.

    Ok, how can I get it to stick with the first image I see instead of the
    seccond (darker/greener)? The first one looks better but then it's gone!

    'Fully-processed version of the RAW data' is not a contradiction in
    terms, because that's what you do with RAW data: Process it.

    I did state it poorly, though. The point being that the camera uses
    whatever's quick to make the preview thumbnail, so it's probably not as
    nice or accurate as whatever your RAW processing software would make.

    Actually the preview IS nicer and more accurate! The processed one is dark
    and greenish, even with ALL the "in camera" settings turned off or
    minimized in Capture NX.

    Yeah, and my point is that you like the preview better than what NX is
    showing you for the RAW data itself. Your question was how to keep it
    from doing the processing, but the answer is that you prefer the
    processed image.

    ....That is, of course, if NX is doing anything like Photoshop's browse
    window.

    The solution, it would seem, is to *keep* the in-camera settings.

  15. Not quite. By definition JPGs are limited to 8 bits. One of the reasons
    many prefer to start with raw is to have access to greater bit depth at the
    start of manipulations and later converting down to 8 bits when desired,
    no?

  16. Greener? Sounds like you may have tweaked you camera's WB setting. Check
    that. If this is the issue try auto WB in the raw processing software. If
    not, then try a standard setting in the more appropriate for the lighting,
    ie daylight, cloudy, shade, etc. I've found both my Nikon D70 and D200 to
    want to be too green is some situations.

    I'm not sure about that. With photoshop, it first reads the embedded
    jpeg thumbnail, then applies the default photoshop contrast adjustments.
    See if you can change the default NX settings to get a more subtle
    default conversion.

    Well, then it is a TIF. Or whatever -- the point is that somehow that
    data has to be processed to create a picture at all.

    Hi Ed,
    Settings> Advanced raw > reset to neutral

    Reset to Neutral
    Selecting this item restores the settings in effect at the time the
    photograph was taken.

    Neither "Advanced raw" nor "reset to neutral" appear as Capture NX
    settings, nor to those phrases appear anywhere in the Capture NX User's
    Guide.
