Is there a way to deal with coloured light to make it look not coloured?

On a recent photo someone pointed out a colour cast which I think was due to light reflecting off a coloured surface. I have other photos were the colour of reflected light makes colours of the photo look weird. Light under a coloured umbrella or the light coming through the red plastic roof of a childrens play house.

I understand that you can tune the white balance when converting from RAW and that you can add "the opposite" colours in PP to neutralize the colour cast. But what if its only in parts of the photo?

Is there anything you can do in camera? Are there any methods that doesn't involve selective pp work?

Thanks,
Jens

Hi Jens , I am wondering if it is the 'under the table' photo you are referring to ?

I think that mostly you have answered your own question here , you could either use a color correction to find the most happy balance , or use one form of selective edit or another.

here is a link to what I figure is one of the best tools for such a selective adjustment

Color Efex Pro 3.0

I have capture nx which is largely based on the same technology as some of the functions of colorefex , the software is available in photoshop plugins .

I purchased the capture nx from a local camera store for 150$ dollars , it is not my favorite piece of software , but in all honesty , its upoint technology is incredible , it would take about 30 seconds to create the adjustment mask for the image 'under the table' and effect color changes limited only to the child's legs. I could place a screen capture of such a mask in your workshop if you would like. capture nx is nikon software , built by nik soft. I believe there are plugins from niksoft for both color and noise reduction using "upoint" in photoshop.

for in camera solutions ? I really don't know of any myself
