    Could someone give me some insight into why these "hot spots" are well within range (around 80-90 on the scale) but they seem to have no detail and be clipped?

    STH, with Mysterium-X sensor?



    Metadata says no interchangeable OLPFs.



    And this looks pretty overexposed to me:






    There's your scorched highlights...

    I did a post about how I changed the OLPFs in the Epic. I now have the skin tone permanently in there because it offers better results.

    Do you see a problem with replacing the OLPF? In the entirety of the thread I didn't hear any "don't do this because..." my tests showed it balanced the color channels better and added more contrast to the image.

    Really?!

    How exactly did it balance "better" when:

    http://www.reduser.net/forum/showthr...=1#post1840869

    Mysterium-X doesn't have a calibration profile for the Standard OLPF.
    or any other profile for that matter, nor can RCXP read it. And how much contrast is correct amount of contrast?

    But, as I said earlier, do what ever you want and don't let anybody tell you different - on the contrary, I'd like to see more parts that don't belong built in. Say ALEV III.
    Or two...double the pleasure.

    First off, the image is really over exposed. Second. change your pipeline to IPP2 and you will see a huge improvement to the image. The ND you are using will also greatly skew the color but thats a different discussion.

    as Sabovic said it was overexposed and the hightlights were clipped. Even when you try to bring it back, there is still no highlight info to recover. If you look at the highlight area the tops are flat and have been harshly cutoff.

    The reason is you've clipped them at the sensor-level, but you have some metadata curves set which are bringing that white-point down to like 90%, giving you the false idea that they should be within range. You're also processing your footage in RedGamma3 which brings that white point down even further than the more current RedGamma4. Clear the curves and set the camera to RedGamma4, and you'll see those highlights get pushed to 100% where you guess they'd be.

    Ultimately I suggest going IPP2 over RedGamma4, though. Processing in IPP2 will run this clip through a highlight extension algorithm, which will rebuild the peaks and allow for a smoother transition to full clipping.

    This helps a lot thank you!
