From 0d9feb0556342a7563dcdce7235dd7513fec200f Mon Sep 17 00:00:00 2001 From: Duncan Tourolle Date: Sun, 27 Sep 2026 16:46:01 -0400 Subject: [PATCH] Describe Tone Mapping and the film's new place in the manual The Light group gains `Tone Mapping`, and a film stock now takes its place at the end of the chain rather than sitting after exposure (D19). Say what the two sliders do and why every adjustment above them works on the scene, highlights beyond white included. The pictures still show the old rendering and are re-recorded separately. --- docs/manual/README.md | 13 ++++++++++++- docs/manual/index.html | 12 +++++++++++- 2 files changed, 23 insertions(+), 2 deletions(-) diff --git a/docs/manual/README.md b/docs/manual/README.md index f0ba1a3..7214aa1 100644 --- a/docs/manual/README.md +++ b/docs/manual/README.md @@ -174,6 +174,15 @@ the strip at its head narrows it to one group.
