    Aperture may not be able to tell what WB the camera is set to.  In any case that is not part of the RAW data. You are free to set the WB to any value you want.

    I am having the same problem with my D800.  The pictures are very dark and print the same way.  I am going to try the Nikon software.  Apple needs to deal with this. It effects many Nikon high end models.

    I have a D800, and shoot only RAW.  No such problem observed here.  Have tested the D600 in a limited fashion, and did not see the problem with it, either.  Tested in 3.4.3, and now 3.4.4 running both on 10.7.5 and 10.8.3.

    I don't know what it is called for Nikon, but you need to turn off any highlight processing. That makes RAW files too dark.

    It's called 'Active D-Lighting' and can create problems. Great in some circumstances when shooting JPEG, but not needed when shooting RAW.

     

    May or may not be corcoraniii's issue.

     

    Who knows what Apple has intended long term for Aperture. Great for some, not so for others.

    Same thing is going on with my Pentax K-30 and Aperture.  If Highlight Protection is enabled, RAW images come out too dark in Aperture.  In fact, they come out exactly one stop too dark.  What Pentax does in Highlight Protection is underexpose by one stop and then boost the preview image and any JPEG conversion exept where in the image it would cause highlight clipping.  I imagine Nikon handles this the same way.  Unfortunately, Aperture doesn't detect the camera setting for highlight protection and simply develops at the one-stop underexposure.  I wish Apple would fix this.

    And no offense to you but my reply is pretty relevant to the actual title of the thread:  "Aperture D600 Raw Files too dark?".  By the way, Active D also is an intentional underexposure and has been been mentioned several times in this thread as having a connection to dark RAW images.  Hope it helps someone.

    Mike,

     

    My latest comments were primarily directed at the reference to a problem with the images from a D800.  However, with respect to my earlier tests with the D600, it was much too limited for me to fully reflect on your issue.  But your observation about blacks being much blacker in the rendering from RAW in those test images, was addressed in a reply by me at the time that the blacks in the portion of the image getting full effect of the flash not showing degrading from that seen in the initial JPEG Preview seems to be pertinet? 

     

    I wish that I could have shot the D600 in the venues I am most familiar with, but in those test shots, the professional photographers at the camera shop did not see the subject problem.

    The "darkness" was not in the original shown on the screen, but snapped in after "Loading" was completed.  I took a shot with "Active D Lighting" off, as suggested and the jump to the darker version did not occur after "Loading" was finished.  Thanks for the obsrvation and advice.  I only tested it on one picture, but I think the suggestion solved the problem.  If it comes back on other pictures with Active D Lighting off, I will let you know.

    Could this be because Aperture displays the embedded JPEG (correct brightness) until the RAW image is fully loaded?

    I shot some additional pictures with "Active D Lighting" Off.  The pictures came out just fine.  It sure seems that Active D Lighting was the culprit.  It turned out that HDR 3 bracket shots done with the HDR Effects Pro plug-in (third party) that came out looking strange were also the result of Active D Lighting being On.  With it Off, they come out as they should.

     

    James, I think it is Active D Lighting itself that is causing the problem.  However, there are so many variables involved, I wouldn't bet my mortgage.

     

    In Nikon's own software, "Active D Lighting" did not seem to make a difference.

     

    Thanks for the knowledgeable suggestion.  And, Corky2, with my last name, guess what my nickname was growing up?

    I must be in good company then!

     

    Nikon's software knows about the Active D-Lighting, so it doesn't surprise me it handles it seamlessly. I believe Apple's current path is to ignore any proprietary in-camera treatment on the RAW files (but uses the imbedded JPEG for preview).

     

    Now if Mike's (OP) issue can be solved. I believe his issue will need to be a fix from Apple though. I see the compressed blacks in his images earlier in the thread and also believe Apple needs to do a little work under the hood to improve the processing somewhat in Aperture.

    Has the Apertue team address this issue yet? My Canon 6D RAW files import much darker a vignetted than they do with the Canon software. Can figure out a fix other than just shooting JPEGs (which is no fix at all).

    Are you using highlight optimization? Turn it off when shooting raw.
