I would like to know what the Develop Assistant > Exposure Bias(option)/Compensation(message) does in APh (1.10.0.244), I am as unclear as the poster below. As the other poster states EC is baked into the pixel data by physically changing the amount of light. The attached image was shot with a +2 EC to make any differences extreme. EB-ApplyExposureBiasAsDefault - Appears to apply the exposure compensation a second time while setting the slider to zero. With +2EC this saturates most pixels. EB-ApplyExposureBiasAsInitialState - Appears to apply the exposure compensation a second time while setting the slider to the EC value in the raw file. With +2EC this saturates most pixels. EB-TakeNoAction - Self explanatory and my current option. Assuming Exposure Bias(option) is the same as Exposure Compensation(message) it would help to use a single term.

Goog morning, I've searched through the forum but didn't found a satisfying answer. What exactly is the difference between "Bias as default" and "Take no action" ? As can be seen in the EXIF data, the image was taken with an underexposure of -1.7 stops. I did the test with "Apply tone curve" as default. Using "Apply exposure bias as initial state" the bias is shown correct in the Exposure section. Using "Apply exposure bias as default" on my screen the image looks +/- the same but the bias in the Exposure section is set to 0 ! Using "Take no action" shows a total different image ! IMHO, opposite to the setting used, a lot of actions must have been executed !
