Hello everyone,


I've recently notice a real bad problem with color saturation in Aperture, or in the OS X 10.8.2 in general when it comes to raw files. But in Aperture, I can notice that "something" happens that destroys the picture.


Here is a movie to show exactly what I mean. I take a raw file, import it into Aperture, and for a few moments you can see the picture as it really is, before the god of ugly saturation jumps in and messes up everything:


So, does anyone know how to fix that? The colors as I see them in real life are like the ones that show up BEFORE whatever is happening happens.


Any help is appreciated, ty.

    That does look quite a bit off from your original image; you might want to contact Apple with feedback to let them know about this:


    In the meantime, you could try sampling the blue from your file in the "Color" adjustment brick, then reducing the saturation and boosting the luminance. You could also try shifting the hue a bit as necessary. Also, if you're shooting RAW+JPEG, make sure to import the JPEGs as well so you have something that you can compare to as you're adjusting the RAW.

    A few things to look at:

    - what are your RAW Fine Tuning settings?  Are they the default for your camera?

    - make sure you are not soft-proofing

    - are you adding any adjustments at import?

    - are you using any in-camera processing?

    - what happens if you change "Aperture➞Preferences➞Import➞Post-Import processing" to "Standard"?

    - what do the files look like in Preview?  Look at the digital-camera file.


    I wouldn't try to back-engineer your RAW Images until you are sure what is going on.

    Most unusual -- watching in stop action there is absolutely no change in the background greens or other than blue content.  This does not seems like the normal change one might see between the initial display of the JPEG preview from the camera and the later change brought about by the decoding of the RAW.


    Is this an Import from a memory card, and if so in the camera or a card reader?  What are the icons I am seeing before the image first appears?

    I agree with Ernie, this is not the normal JPG preview to RAW change that you would expect, only the items in the foreground changed color.


    How are you importing this? Where did the image come from, the naming of the file seems to indicate it was first placed onto your system and then imported.

    As far as I can tell from the abreviated screenshots, none of these look very much like the initial Preview you had in the QT video.


    Do you have somewhere you could place this RAW .CR2 file that I could download from?  You can find my email address by clicking on my name to the left of any of my posts, and looking in the bio line.

    Got it.  I have been able to capture the Preview before Aperture generated a new one, and here on my 23" Cinema Display, the only change seems to be in the "blue things" and not in the back ground, as was shown in your video.


    Photoshop CS5 opens the file to be much deeper in blue color than the original Preview, but not quite as deep as the one Aperture generates.


    Graphic Converter, which to my knowledge does not use the Apple Digital Raw looks very much like that in Aperture.


    From the EXIF data, it appears that the camera was not set on anything special to take the shot, and influence the JPEG Preview.


    Very curious, and I will put more thought on it tomorrow.
