Blue in Hair
I had my subject too close to the Chroma-blue background and now there is some blue reflection in her blond hair - is there a simple way to fix this?
i would just use the clone stamp .... that should take care of it
if you really want to get creative grab the airbrush for some touchups
Try the following:
1. Select the hair with the Lasso Tool
2. Open Hue/Saturation dialog [Ctrl+U]
3. In the dialog's "Edit" menu choose Blue (perhapse, Cyan or Magenta) color range and reduce its saturation.
