Lightroom 2 ND Grad Filter It looks great as a 16-bit image, but I get pretty shitty color banding when in 8-bit color mode. What I don't get is that photos that have natural gradients don't show banding when in 8-bit mode. is this because my camera (D50) shoots in 12-bit color mode so going down to 8-bit isn't a big change. but going from the "artificial" 16-bit gradient in LR to 8-bit is? how can I correct this? is there way to export the image in LightRoom so it doesn't have banding as an 8-bit file?
