[QUOTE="J-see, post: 409308, member: 31330"] I think the color shift has less to do with the light levels. It is true that the less information the sensor receives, the less accurate the RAW file will be. But that same shift in colors happens during all light levels. I can shoot the same shot increasing ISO each time and thus overexposing but when normalizing in post, the colors are fairly identical. The same is not true for shooting low and increasing exposure in post. I have few problems with the color shift up to three stops but the moment I go beyond those, the color shift becomes fairly strong but from what I see, mainly limited to the shadows. There's a 0.5EV difference in the shadows between 100 and 6400 so maybe there it got clipped in one color channel. I have to compare them. I'm reading up upon it and it seems WB affects the % of colors that are present in each channel. I think the problem also could be situated there. The luminosity levels are identical and the colors are but a profile attached to the RAW. It's when loading this profile and adjusting it in a RAW editor, there's some issue with how the colors scale in relation to exposure increase. This might be true for every exposure difference but I assume since the difference in exposure is seldom as huge as what I am doing, we don't really notice. [/QUOTE]
