Curvemeister Forum

LAB first. Used a set neutral in the lighter shadow under the chairs. This got rid of most of the blue colour cast.
Moved saturation up and steepened the curve at the dark end.
The opened in RGB. Didn't think there was any blue still remaining under the chairs until I moved the blue dark end about half a square then noticed the slight change to a more natural sandy colour. Great suggestions in the session notes.
Amazing how such simple changes can make such a huge change to an image.

Am I correct in thinking there may be a slight yellow colour cast now?

The problem isn't too much yellow, but too much green in the foliage - on my monitor it looks oversaturated.  In general, foliage should be more yellow than green on the hue clock.  The sand and sky are great, so I would concentrate on the green half of the a curve in Lab mode to level out the green a bit, without affecting the sky.
