From f4c3f425ddab7bfd1c08852f890f3c2f785efb79 Mon Sep 17 00:00:00 2001 From: Duncan Tourolle Date: Sun, 20 Sep 2026 15:24:27 +0200 Subject: [PATCH] Show the picker correcting something in the manual The recording sampled a red brick wall and moved the sliders by three units, which at GIF size is a click that does nothing. The scene now drags the frame cold first and picks a white air conditioner, so the correction is visible and the picker's being absolute - set from the photograph, not from where the sliders were - is what the picture shows. The text says so, and says a blown highlight is refused. --- docs/manual/README.md | 8 ++++++-- docs/manual/media/develop-wb.gif | 4 ++-- tools/manual/scenes.py | 3 ++- 3 files changed, 10 insertions(+), 5 deletions(-) diff --git a/docs/manual/README.md b/docs/manual/README.md index 0134f81..7c6303d 100644 --- a/docs/manual/README.md +++ b/docs/manual/README.md @@ -99,9 +99,13 @@ wheel zooms to any amount in between. ### White balance from the photograph -Press `pick` in the White Balance group, then click something neutral. +Press `pick` in the White Balance group, then click something neutral — +a white wall, a grey card, the air conditioner here.
