I guess I have a novice question. I have rarely used exposure compensation in my photography thus far. It's probably due to a lack of understanding. I understand the concept of E.C. tricking the camera into creating brighter or darker exposures for a specific scene. What I don't understand is how this technique differs from just increasing or decreasing exposure in post processing? I started to believe they create the same results. If I'm wrong, please let me know so I can improve! I have been taking portraits more frequently and I am just trying to understand the tools available to me. Thanks!
