Description

Used in IFD 0 or Camera Profile IFD of DNG files.

Provides a way for color profiles to increase or decrease exposure during raw conversion.

BaselineExposureOffset specifies the amount (in EV units) to add to the BaselineExposure tag during image rendering. For example, if the BaselineExposure value for a given camera model is +0.3, and the BaselineExposureOffset value for a given camera profile used to render an image for that camera model is -0.7, then the actual default exposure value used during rendering will be +0.3 - 0.7 = -0.4.
