Done Mononodes RGB Split Tone V2

RGB Split Tone V2 is a camera space aware split toning tool that works directly in your chosen Input Log. Select the log and the adjustments happen in that space. Instead of bending freehand curves, you use precise sliders with soft knees and optional white and black protection. Whites and blacks can stay neutral, or be intentionally split for creative effect. Highlights, shadows, and mid gray stay where you set them, making results predictable and repeatable without anchor point juggling or unexpected hue shifts
