I shoot in RAW ( Canon 5d MKII).  I typically have the camera set to Auto White Balance, then adjust as needed in Aperture.

I recently shot a sunrise ans and sunset and had the camera set to 10,000k.  When I brought the pictures into Apeerture they had a blue green cast.  I had to set the temperture to get the 10,000 k that I wanted.  Does Aperture ignore the white balance setting of the camera when it imports and process RAW files?  Or am I missing something?

I am on the latest version of Aperture. 

MacBook Pro (17-inch Mid 2010), OS X Mountain Lion (10.8.2), Aperture, FCP X

    Yes, it does its own white balance and ignores the camera setting.


    After all, the whole point of shooting in RAW is to *not* have the camera set the white balance. If you like what the camera does, use JPEG.

    Keith is right in principle -- I'm not sure he's 100% right in practice.  If you search this forum and the Web you'll find that some people report that Aperture uses some of the WB information in the metadata to render the Image (Canon), while others report (as Keith states) that Aperture does not.


    I don't know.  I always use AWB.  I record only RAW files.  The WB I see in Aperture is usually excellent (so much so that I stopped using gray cards and my X-Rite Passport).  But for sunsets and sunrise, and red flowers, the WB is far from what I want.


    I treat WB as an artistic decision.  Most people's vision is so far from purely ocular that rendering things as they look to a light recording device is not desirable.


    Here are links to articles I found very useful when I was puzzling this out:

    I just looked through my Canon 5D MKII raw pictures - no sunrise pictures unfortunately. The closest I could get, is this record from our recent experiments, nothing artistic:

    But I noticed that the recent raw update treats the white balance settings differently for the Canon from previous raw support versions. The screenshot above shows the original image, taken last year, with a warning that the raw support has changed, and if I want to reprocess. The image to the right is the same image after reprocessing, and it has a slightly blue-green tint after reprocessing the raw.

    Thanks for the responses.  I haven't been quick to respond because I am traveling in the soutwest currently and don't have internet at  every site.


    I have reada few  post on this forum about issues with a green cast to raw images taken with some Cannon's once they were processed by Aperture, but I hadn't really noticed much of an issue until I got to the soutwest.  I don't know if it's becaise of the altitudes(6,000 - 8,000 feet) or the predomance of reds in the landscape, but I am sure noticing it now. Much like leonieDF's example. I am looking at them on my MBP's 17 " screen, but I suspect my monitor back home will show the same cast.


    I guess I was expecting Aperture to adjust the white balance towards the shot setting.  But it sure doesn't seem to pay any attention to the white balance setting of the camera ( Canon ), in fact it might be going in the opposite direction.


    I did go through the links Kirby suggested.  I had read the Cambridge article before, but it was a great reminder.


    Thanks again for the replies.
