Using DPP quite often I never had any problem like this. Only thing that comes to my mind:
- Please check version. Latest should be 4.12.20 or higher
- Did you check the settings of the color space? (sRGB vs. Adobe RGB, etc)
Maybe settings in DPP and you viewer or tool for further processing are different.
- I am assuming that you are using the same PC/display for working in DPP and viewer or tool for further processing
Otherwise different dislpay graphic processor settings could cause problems, too. But not that much IMO.
If that is not the case, I'd contact Canon service or hope for more clever here.
On a second thought:
8000 K seem quite high IMO, depending on the lighting.
Did you try at normal AWB setting to achieve a better color using saturation and color tone ( I don't know the right name as I use the German UI)?
So getting to a more red tone.
I looked at this some more and here's what I noticed.
As I am working with the RAW file, the thumbnail looks different from what I see in the editor--and now I am noticing I don't like what I see in the editor either. (The thumbnail actually looks exactly like what I want.) When I create a TIFF or JPG its thumbnail will also show up, and will look red. So basically, DPP doesn't thumbnail the raw files properly, but does thumbnail the others correctly. That's peculiar. I think there's a very small amount of change in creating the TIFF, but it's far less than the difference between the RAW's thumbnail and the RAW itself.
I'll check the version number. I'd be very surprised if it's fully up to date but at least it *is* 4-point-something.
Auto/Normal color balance leaves me with coins that look like dull bronze. Even setting a custom balance doesn't seem to work--dull bronze again. So I ended up using "shade" to take the picture, which at least makes them look yellow, but then it still needs to be a bit more orange to match the way the coins look in hand, so I have been adjusting anything from 8K to 10K to do it. However, I'm going to have to go back and rethink that, because that's probably where I've been introducing a lot of the redness that the thumbnails won't show. In some cases I get what I wanted, in other cases, I most assuredly did not!
In any case, my gripe with DPP right now is the RAW thumbnails don't match what has really been done with the raw files in fact. (And yes, I know the RAW files themselves haven't changed; it's just that a "recipe" is being applied to them to show me what I see...a very good system, IMHO.)
