Canon SL2: I placed the camera as a very difficult lighting space where I tried my best to keep the highlights from clipping using Underexposure vs Highlight Tone Priority. The Shadows in both are going to suffer but which one looks the best? Let me know in the comments!
What I learned: There’s an increase in noise when using HTP than Prolost Flat EV@0 (although clipping in highlights). I took the Prolost Flat EV@(0) and took it one stop down resulting in Prolost Flat EV@(-1) then Edited the image back to normal.
Prolost Flat EV@(-1) Edited saved the highlights, but created noise comparable to HTP. The difference that I noticed were the colors. The colors on the Prolost Flat EV@(-1) Edited changed when bringing the shadows up (looks worse) and the HTP retained most (lost some) of the colors in the shadows.
Recommendation: Use HTP in more brighter scenes that’s uncontrollable. If the scene is controllable, just turn it off.
Prolost Flat: 100 ISO; F2.8; 50th; EV@-1
Prolost Flat w/Highlight Tone Priority: 200 ISO; F2.8; 50th; EV@0
