Oups, only 42% quality by saving for web.
Don't look that colorful, that the file could be so big...

Tanja,
When I test these I use the saturation slider in LAB to help me figure out a color cast. 

Shot 1 is your original image supersaturated.

Shot 2 is your image supersaturated with a different neutral choice.

Oups...  ;D

Hm, did I have the right points? Still looks so blue.
Was there another step to color correction? I don't remember...
Good to have the video tomorrow  ;)

Greeting, Tanja

Tanja,
Indeed it is too blue...

I think you choose a part of the pipe that was too blue.  The sample itself should be 3X3 pixels and you need to make sure you find a good spot for the neutral after shopping it around a bit.
I have attached my curve files for the image you have posted to the web...They fix that version.

I adjusted the a and b channels in lab just a bit to reduce the blue in the overall image.

Hm, funny... I set the sample on 3x3 last week, but you're right, Greg. It was on 5x5 again.
Did some action in cm mabe make a reset?

Not much time this week. Hope I can catch up next week.

Greetings, Tanja

Unbelievable! I don't find that correct neutral point.
Try now to correct with a and b channel by view.
Still don't look like I want to, but hopefully better.

Greetings, Tanja

The water is definitely too blue...

This looks like a job for CMYK.  Subtle corrections are needed here.

See my screen shot and Curve file attached:

Hi Greg,

jep, looks better with your correction.
But I don't wanna loose all the nice colors in the stones.
What do you think about your correction with a mask?

Greetings, Tanja

Well Which channel would you use??
