@janamarie@mystical.garden what was your channel mapping with these? My IR shot all come out a dirty pink. This is much more like what I hoped for

@SEGFAULT@oldbytes.space what filter do you use? for this white foliage you want to use a ~720nm long-pass filter. I use the second colour inversion as described here: https://blog.janamarie.dev/irphotography.html, the imagemagick command would be magick $INPUT -color-matrix ' 0 0 1 1 0 0 0 1 0 ' $OUTPUT if you write out the colour matrix, it becomes a bit more readable .
