- Date: Sun, 24 Jan 2016 03:24:44 +0000 (UTC)
commit a2ae6b14f5dedcc7202d3e957e8b0a236d475c9d
Author: Debarshi Ray <debarshir gnome org>
Date: Tue Jan 12 18:34:51 2016 +0100
Add Instagram Hefe
The filter is implemented by a hidden meta-operation called
photos:insta-hefe, which in turn uses photos:insta-hefe-curve,
photos:insta-hefe-vignette and svg:multiply.
Based on an analysis by Corey Hoard <corey coreyhoard com>:
