💖 NAME 💖

ocal_tone_map — bestie, it's literally just called ocal_tone_map, that's the whole name, iconic minimalism honestly 🎀

✨ SYNOPSIS ✨

local_tone_map input output [OPTIONS...]

okay so heads up: the header up top says OCAL_TONE_MAP and the synopsis says local_tone_map. Not me editing the drama out — I'm keeping both exactly as they are, fr fr 👑

🌸 DESCRIPTION 🌸

This is the tone-mapping girlie. She takes an image in, hands you an image out, and lets you tweak a couple of things along the way. Simple. Elegant. Main character energy 💅

• -s 0..1, --preserve_saturation=0..1 — lowkey the only knob that matters — this sets to what extent to try and preserve saturation over luminance. The value goes from 0 to 1, so dial it like a vibe check: how much saturation are we protecting while the luminance does its thing? 😌
• input — the input image 🖼️ the one you're bringing to the party.
• output — the output image ✨ the one you leave with.
• -h, --help — prints this help message. And yes, all options are shown above — that's the entire menu, no secret items, no hidden DLC 🫶
