💖 DESCRIPTION 💖

So here's the whole menu, no gatekeeping, every option's right here for you 🫶

• -t nits, --target_nits=nits — this sets the peak luminance of the target display. Like, how bright is the screen gonna go? That's the number.
• -s nits, --surround_nits=nits — the surround luminance of the viewing environment. Basically how lit up the room around you is. Default is 5, no cap.
• --preserve_saturation=0..1 — this one's for when a gamma < 1 generates out-of-gamut colors 😭 it controls to what extent to try and preserve saturation over luminance. Slider from 0 to 1, pick your fighter.
• -p, --pq — writes the output with absolute luminance using PQ. Periodt.
• input — the input image. The one you're feeding in 🌸
• output — the output image. The glow-up that comes out the other side ✨
• -h, --help — Prints this help message. All options are shown above. Obsessed with the efficiency honestly 👑
