Colour filters behave very differently in different colour space

corrected version !

I did a (criss) cross test in PL8 with a ProPhoto TIFF file and a converted sRGB version,
each in WideGamut (WG) and Legacy (Leg) working color space,
and used the Black & white film simulation Fuji Neopan Acros 100 (FP).

You can download “riwodot colortest I.tif”


from https://riwodot.de/colormanagement.html
or directly ( → link )
.
To get an sRGB version I exported the file to [sRGB + Preserve color details ]
and renamed it to “riwodot sRGB.tif”

no filter

  • orange = Wide Gamut
  • yellow = Legacy

with red filter

  • green = Wide Gamut
  • blue = Legacy *)

.

*) Adding a red filter (FilmPack) when set to Legacy also influenced the white point and darkened the whole pic. → Compare and check histogram!

  • ProPhoto:
    WG = 253 ↔ Leg = 231

  • sRGB:
    WG = 253 ↔ Leg = 236
