No, I didn't delve too much into Barrie's photographic exploits, not least because there wasn't much evidence to go on, other than the photographs themselves, variously spread across different family albums. Nico found a number of original nitrate negatives at the back of an old drawer, from which I made new prints (we had a darkroom in those days), and I've uploaded both negatives and prints to the database.
Barrie had a touch of the "been there, done that" about some of his enthusiasms. He had a camera early on, before the arrival of the Davies boys - see his photos of Bevil Quiller-Couch for instance, which he compiled into an album called "The Pippa & Porthos", but it seems that he lost interest in photography around the time of Sylvia's death. Similarly he was an early enthusiast of cinema, and made a silent movie in 1915 called "The Real Thing at Last", being a parody of Hollywood film-making, but lost interest once Paramount dumped his own screenplay for Peter Pan ...
I've uploaded an article in a Photographic magazine from 1980 - not particularly well-written or informative, and mostly me blabbing to whoever wrote the article, but it does touch on what little we know about Barrie and photography.
btw, I'm gradually replacing all the photographs on this site with higher resolution scans (and without irritating watermarks) in chronological order - I'm up to 1912 - but with so much else going on it will take a while longer; hopefully by this time next year the site will be close to the one I first imagined back in 1999 ...
