That's my understanding either. So I'm pretty surprized (or rather puzzled), that the specified (standardized?) method to convert from the film density based log encoding to video RGB only involves 1-dimensonal TRCs. I guess, this can only be a rough approximation. Regards, Gerhard -- Weitersagen: GMX DSL-Flatrates mit Tempo-Garantie!
