Raw Color Treatment

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:

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...

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.

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:

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

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

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.

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.
