Oh it is an open secret :)
While I have one beloved acquaintance who owns such ancient equipment for developing film I — being supremely smitten with everything ˋnostalgic´ and editing in general but without suchlike tools and toys — created the flair digitally... I can show you the colored version of this one impression here as well if you would like to :)

And thanks so much for referring to me as ˋgreat artist´ ~ that certainly is one amazing compliment indeed...!.....
