A friend of mine asked me a good question and that is why does his Library module look so much different from his Develop module. I had a look at his modules and the difference was at least 1-1.5 stops Library being darker than develop. I made sure he was using the correct color space for the Library module set to Adobe RGB1998. However this made no difference, yet when I look at mine they are almost exactly the same. Anyone have any idea why his is so different?
