    Just wondering which gamma curve takes the most use out of the MX Chip in the Scarlet and provides the widest dynamic range and highlight protection? Is Log3G12 built for newer sensors or can I actually benefit from it on the MX Sensor?

    Mike,


    The IPP2 RedWideGamut/ LOG3G10 Color Space and Gamma was designed to optimize the images from the RED Sensors in both Old and New Red Cameras

    You're Welcome Mike!

    Here's a "White Paper" that explains both the REDWideGamutRGB and LOG3G10 components a little better and how they come together inside of the IPP2 Workflow.

    Yeah, just to confirm, along with RWG/Log3G10, IPP2 had debayer tweaks for sharper/cleaner images and it has a bit of highlight reconstruction (to eeek out a bit more roll-off detail). Nothing magical mind you, but hey, it's free!

    So yeah, it's better all around. The only time I'd use RLF is if you have an established workflow that does a lot of what IPP2 does manually/by hand/eye...

    Everyone covered everything already but I do want to add that Log3g10 is the one you want to use, not Log3g12. As I understand, that gamma curve allows more dynamic range (12 stops over mid grey, hence the name) at the cost of some precision. G10 (10 stops over mid grey) is more suitable for all current and past cameras.

    Interesting. So, why have the LOG3G12 at all? Or is that something specific to working in a HDR workflow?
