Comment (by Jozef Chutka):

 Thanks for the quick response Michael. I would love to use `imin`, `imax`,
 `omin`, `omax` on `colorlevels`, however this doesnt seem to work in
 ffmpeg version N-108353-g7cd252ee41-20220925

 {{{
 ffmpeg -i img.jpg -vf "colorlevels=imin=0.5" -y imin.jpg

 [Parsed_colorlevels_0 @ 0000023283b4ecc0] Option 'imin' not found
 [AVFilterGraph @ 0000023283b4df40] Error initializing filter 'colorlevels'
 with args 'imin=0.5'
 Error reinitializing filters!
 Failed to inject frame into filter network: Option not found
 Error while processing the decoded data for stream #0:0
 Conversion failed!
 }}}

 As being slightly unrelated, do you want me to create a separate ticket?
