I do coulour correction by the numbers in the info pallete adn use the multiple referance point eye dropper tool to find the right level I can definly say with this method you will not only see the cast in the picture but also when adjusting curves and levels having the info pallet in view as you change the gamut of the image. detail in the shadow end is not notice able enogh to draw the eye away from this large higlight you may want to increase the level of the mid-tones to make this highlight less obvious. when I get home I can actually do it .. so wait and see... I hope you are pleased with the result... I will be using a mac to do it.. but if you have a good monitor on your PC and a good callibration techinques .. hopefully what I do to the image is satisfactory... I will not use auto curves and use a large History brush @ 50% it's far to easy.... LOL but I will show the result : D BRB
