Raw processing of EOS 60D pictures becomes too red

[larswuckel]

Hello

I switched from the Canon EOS 30d to the 60d. But now I have a problem with the 60d photos and the raw-processor inside Aftershot Pro.

The raw photos of the 60d will be processed always too red. I have made a screenshot with Aftershot Pro 1.1 and Canons Digital Photo Professional to compare the results.
In DPP the colors are naturally. In ASP is a red tinge.

So I think the tone curve of the 60d for the raw processor is not the right inside the ASP.

Is there a fix?

The raw-photos of the EOS 30d becomes processed withe the right colors in ASP. So the bug is only while using 60d raw photos.

The only workaround for now is to profile the cam yourself.

... or try the icc profile of another Canon in the "colour management"-tab (as a "custom input profile"). Try the profiles that come with AftershotPro; if you find a profile that gives you pleasant colours, you can save it as a default.

Good luck with that. ;-(
Since the latest version of B5, the profiles are no longer individually available...

I also have a 60D but the only other cameras I have is a G11. But neither have the reddish tint you are finding. Clearly I do not have your file to try but I haven’t seen this with any I have used. I am using a Dell laptop with a ATI Radeon HD 5400 so hardly high end monitor but its calibrated with Spyder4Pro (my wife does have a high color HP monitor (that is noticeably better than my Dell!)so I pinch her Spyder). So I don’t understand why you are getting it but I am OK?

@john7:

My monitor is calibrated with spider3. The colors of my 30d photos were always good. But with my 60D I get such reddish tint.

Maybe it's an important fact that I get this tint always in photos while using the flashlight ?!


@afx:

How can I profile the cam by myself?

Have tried a custom WB when using the flash?
What happens when you tell AS explicitly to use the flash WB preset?

To generate you own profile you need a decent target (a colorchecker is sort of ok, but targets with significantly more patches will help, the target needs to be supported by ArgyllCMS).
Shoot the target properly exposed, then use AS in no CMS mode with an exposure adjustment of +2 (bug workaround) and no other adjustments to generate a TIFF that is then analyzed with ArgyllCMS to generate a profile.
The base mechanism is described here: http://blog.pcode.nl/2010/06/28/darktab ... profiling/

Hi I have had a look at some of my flash and I attach one in DPP and in ASP. There doesn't look to be much difference between them, this was using a Speedlight 430xII with a defuser. I also looked at some taken at a public meeting and other events but non appeared to have a red in them in. Being new to the program by white balance I notice was as shot in both programs.

@john7

Thank you for your photo compare example. I can see that the red portion in ASP is too much. Yellow is not yellow.
I think that ASP has a problem with the input icc-profile, so that you have to adjust the white balance or the tone curve.

In my example photo there is more red inside. So that is easier to notice. For that photo I used a 580EX II.
With my EOS 30D I had never such color problems before.


I tried now Lightzone and Rawtherapee (with the 60d icc). Nearly the same result with Lightzone.
The result of RawTherapee was very good. See attachment.


Maybe the developers of ASP can copy some values from rawtherapee to fix this bug?

@afx

No custom WB.
the flash WB in ASP didn't fix the red tint.

I noticed I hadn't turned on the camera profile and when I did it made no difference at all. Looking again yes there is too much red, I hadn't noticed the histogram (I am new at this!). Fiddling with the curves (selecting red) corrected it. So it doesn't look to be the 60D profile that's the isue but the program?

?? Where are you turning on the camera profile?

Hi
Under detail I have enable correction; the first options are cameras then lenses. I take it unselected the camera and lens corrections are unused.
sorry to take so long but my camera bar had vanished so I had to find out how to reset the tool bars.

[afx]

Lens correction is completely irrelevant for the color profile.

[john7]

Sorry you are right, on recooking it is an option for lenses, I thought it was for the camera as well.
