John on Nostr: A pixel delta (difference) between a Rec. 601 colour profile and a wide sRGB colour ...
A pixel delta (difference) between a Rec. 601 colour profile and a wide sRGB colour profile, which I mapped lighter so it's visible. Obviously measurement accuracy is lost in the JPEG conversion but I did the original in uncompressed 8bit PNG (maybe 16bit tiff would be most accurate but overkill). Quite psychedelic. #lunch
