    Just in case, you may want to check to see if there's any firmware updates for your Canon camera. Sometimes camera manufacturers alter their RAW formats in different firmware revisions.

     

    Here's where you'd download it: http://www.usa.canon.com/cusa/support/consumer/eos_slr_camera_systems/eos_digita l_slr_cameras/eos_20d#DriversAndSoftware

    Hi Aye,

     

    Yes, my firmware is 2.0.3. Interesting though is that Canon just released a new version of their RAW software. I'll try working with it to see if there is any major differences.

     

    Thank you.

    Oh, look at this one!

     

    The same screenshot as before, but now with the Canon DPP window:

    http://cl.ly/image/332y2a3T1X1i

     

    Apparently, the ONLY program that can read the RAW and produce colors as they really were (or as I remember them to be) is Canon's...

     

    Which just puts me into a so big of a headache right now...

    Well, at least you can export 16-bit TIFFs out of DPP and work on them in Aperture, in that case.

    Aye,

     

    That is true, but considering how often Apple updates technologies, I wonder if that would be a solution for a good while or not.

     

    Still, it doesn't cover for the fact that the algorithm to deal with CR2 is broken.

    Here are the Previews, before and after Aperture decoding.  It does not seem to me that your Canon software matches the Preview from the camera, either?

    The way I captured the before was to Import the RAW into an existing Project where it would not then be immediately displayed.  Then I opened the Package of the Library, and then the Previews folder and copied the initial Preview prior to its being replaced by one generated by Aperture.

     

    I fear that the problem in Apple Digital Camera RAW is that older cameras are not being well considered in updates.  If I can find an older version of Aperture with an older version of Camera RAW in use, I will test.

     

    Btw, I do not see anything like this difference in any photos I make with my Nikon D300 or D800 between the initial Preview and the next one generated by Aperture.  To be clear, I am suggesting it would not impact all CR2 files from all Canon cameras -- we would have lots more reports were that the case.

    Ernie,

     

    I agree with you. Problem is, I had never noticed this until I got this blueish problem, and I use the camera since 2005.

     

    I don't think the vast majority of photographers would ever even consider such a bisarre result from a professional product as Aperture. I, and I believe many more, simply assumed that the program would give me a high quality RAW treatment, otherwise, why the heck to buy it since you can have the same with iPhoto?

     

    To me, this is really really bad.

     

    Anyway, that trick of the preview is indeed very nice, thank you so much for that hint, I didn't know I could do that. I'll defintelly reimport and check a few pictures I took that I remember I questioned the colors.

     

    Now, for a final comparison, I took the preview from Aperture and made a cut to compare with DPP. I pasted a strip in the middle with what comes out of DPP. If you divide the image in four stripes, 1 and 4 are from the Camera Preview, while the two in the middle are from DPP. I made two red lines on top to help you find the cuts. Check this out:

    CPreview_versus_DPP.jpg

     

    We can clearly see a line in both tubes, but the color difference is way too small to bother.

    Ernie -- Afaik, "CR2" and other proprietary RAW designations are not standardized: in many cases, each camera from a manufacturer has it's own specific RAW file format, even though they may share a filename extension.  IOW, to specify the exact file format, one needs both the filename extension, and some information from the file (perhaps in the EXIF).  It makes sense that the difference you have found is not found in all CR2 files, just as it makes sense that the only program that seems to correctly interpret all CR2 files is provided by Canon.

    Clever!  .

    Booted up in Snow Leopard, with Aperture 3.2.4, and Digital Camera RAW 3.13.0, and no difference in the RAW decoding of this one photo.  Of course that version of Aperture and earlier never displayed the camera Preview.

     

    When time allows, I will look for an older version of Aperture and Camera RAW to test with.

    I just took the time to review a few other pictures. Most of them come out with extreme use of colors.

     

    To my surprise, although more subtle, there are still very noticeable differences.

     

    Aperture always on the left half, while DPP always on the right half.

    So, orange, purple, even some pink are too colorful and red becomes a bit of pink with yellow being overshadowed by red. Quite the party. =p

    On these particular images, insofar as can be seen here, I would probably prefer the Aperture version as the starting point for any adjustment I might make.

     

    However, on your original deep blue image, adjust path was immediately discerned.

    Ernie,

     

    If one would go with Aperture or DPP, that is more taste and perhaps treatments than a problem. I can easily work with Aperture's results, although none of the comparisons, as you said, present the problem as in that first blue image.

     

    What I wanted to add to the "case" by posting those, is that my Apple RAW / Aperture is working properly and that the camera is providing good pictures. It is not as if one or another is completely off.

     

    However, on that picture, the blue was really really off, and that is a problem with the RAW algorithm implemented by Apple. I have 3 more shots besides that particular one I shared in which the results were exactly the same.

     

    I would take that one picture could have gone wrong, but not 4, and absolutely not the only 4 about the same subject under the same light conditions.

     

    Anyway, if you ever get to do those tests on another Aperture / RAW version, let me know, I'm curious. =)

     

    Thank you so far for all the help.

  • 27. Re: Raw Color Treatment

    I will do that.  It would be interesting to have the same shot from a different 20D, as well.

  • 28. Re: Raw Color Treatment
    morph21 Level 1 Level 1 (10 points)

    I just did something extremely silly, but yet, managed to achieve the same results, the blueish problem.

     

    Had the picture in fullscreen in my iMac 27", took a picture of it, the screen itself, imported into Aperture and had the same problem.

     

    Now, perhaps if someone else with a good screen and a 20d could try that out, we might see if it will reproduce the issue.

  • 29. Re: Raw Color Treatment
    Ernie Stamper Level 8 Level 8 (37,475 points)

    Not sure what that reproduces, unless you are telling me that in the camera and initial Preview the blue is different?  I would think a similar object/scene would have to be photographed to tell us anything about the 20d.
