Piotr sent me his video with the following text:
I have just posted a 50 minute LUMIX S9 in-depth walkthrough for hybrid shooters. It is packed with great info and I also cover 2 custom settings that I think a lot of S9 owners would find really useful.
1. Red Record button is programmed to be a ‘Leica Monochrome’ button – handy for quick B&W shots.
2. LUT Button was a bit limiting out of the box, so programming it to ‘My Photo Style 1’ gives a lot more options like stacking 2 LUT’s and not losing grain settings every time you change the LUT (Which happened when you use the Real Time LUT menu).
