- Date: Sat, 15 May 2021 20:55:31 +0000 (UTC)
commit 3d5e9bc8be061c1f52ffe375f06f8e3e15d22f56
Author: JonnyRobbie <marcodv seznam cz>
Date: Fri May 14 09:55:24 2021 +0200
Update, fix and improve negative-darkroom operation
* Rework emulsion dye model to (hopefully) properly simulate colors
(this also fixes issue with multigrade paper)
* Rework color filter model with UI improvements.
* Rework sensitivity matrix calculation to (hopefully) properly
represent paper properties.
* Add more black and white papers.
