While I'm still here... I thought this might be of interest to video producers. A short 1927 film, shot by a pioneer of film production and employing the colour processes of his father (William Friese-Greene, obviously). If you ever want to emulate the colour tones of that era, here's your visual reference.
I'm not a videographer myself, but it was fascinating to me as my grandmother (a lifelong Londoner) would have been 20 at that time, and my mother would be born one year after this film was made. I was amazed to see so many men and so few women at Petticoat Lane. How times have changed!
Sorry about the references to 'Empire' and all that in there... please ignore those. They're the author's words and sentiments, not mine.
