Zog,
I appreciate the humor and grace...
Mike and I scour the archives looking for the best of the worst images for the class...If they were easy...well where's the fun in that.
For my take on the image you stated that: "Here is a a mixed lighting shot - the stone is not painted it is all the same colour"
I took the blue light to be the natural light of the scene and worked to make the yellow sodium light disappear.
I prefer natural light when it is there (Personal Bias) To me the yellow was the problem to be solved not necessarily the color to be matched.
During my analysis of the image I saw two really big problems...
1) Yellow lights in the arches
2) The stained glass.
Secondary issues were the correct colors for the darker parts of the ceiling, control of the shadows near the alter and color saturation since I knew from the get go I was killing colors off in the image....not having been there I felt I had a bit of room there. Now that I look at the other images provided I see that I went too far in that regard...
The limits in CM were mostly curve guard issues that I over came with a mask. Since I did not need to adjust for any other color except the yellow I was free to lock down the blue side of the B channel and crank it up to see what I could do. I ended up making the B curve flat on the central axis to the center and then using a "Contrast Pin" to link two points on the curve I lifted the entire B curve upwards so that the bluish cast in other areas was reduced. Control points were removed as I went to keep the blue side of the B channel in line.
I would say to you and any others that if great images are the goal nothing you can do is cheating. No one is going to have a penalty for success....
For the purpose of the class we want to learn how to use CM. To that end I would say you "cheated" but... I think Jacob's Ladder is a interesting curves technique that Mike is going to have to wrestle with going forward. I am still trying to get my brain wrapped around it. for those still trying to understand the jacob's ladder technique you can read about it in http://www.curvemeister.com/forum/index.php?topic=2078.0
Just as I would caution anyone getting too locked into a single color space I would say that JL has a time and place. Just as LAB might be a better space than RGB in some situations or HSB has advantage over CMYK.
Everyone remember that this week is a time to push some limits and see what this plug in can do...Again don't get scared off...There is much to learn but loads of help.....
