Thank you very much. Turning down the blue/cyan colors gave the best results, but I'm happy knowing about the white balance plugin. I've gotten better results with Paint.net than with all my efforts with Photoshop. Although the modified picture has had it's colors corrected, when I view the picture in Thumbnail or Filmstrip mode, the small thumbnail still shows the deep blue of the original picture. How is it that after correctingthe color problem, the problem has not been corrected in the thumbnail?
