Red Channel from G/B? Help.
      #3396098 - 10/18/09 12:12 PM Attachment (4 downloads)

My XSi-DSS tool chain is consistently producing Red channel that is much much worse than Blue and Green. As the result my RGB images look either lacking Red channel if I suppress the red channel, or they start looking very noisy, especially in dark parts of the image.

Why is this happening? And second, is it possible to use Green and Blue to somehow reconstruct Red channel? I think I saw some techniques to get channels reconstructed for "pseudo-RGB".
