Ah, I see. Well, thanks for that, chiboy

I think I've found your photographer. His full name (maybe in fact his business name) was Tung Hing.
You'll need to scroll through the link (below) a bit and look closely to find him.
I'd bet money that this is our fellow. It's a shame that most of the really talented Chinese photographers of the period have been ignored by history. You'll read how westerners on a visit to Hong Kong and Shanghai in the 19th C. sought out these esteemed photographer guys, whose reputation carried around the world even back then. A bit like how the really great tailors of today here in Hong Kong are well-known by the cognoscenti in New York, London and so on.
The article is really worth a look all through. PM me if you can't make the link work.
