I have created a new HDRP project in 2019.3.0f1 and it has the default HDRP scene in it. Without changing anything I run the application and change only the Exposure value on the post-processing Volume. What I get is the inverted behavior where less exposure makes the scene brighter and more exposure makes it darker. How is this possible? What am I missing to understand how this works? Here is the video: I have tried it in some of the 2019.3.x and 2019.2.x and it always behaves the same. I had experience working with some Unity projects before where the behavior of Exposure was not inverted, I don't know how it was achieved but it seemed much more natural.
