See the original photo in the Wellcome Collection. We have the photo on Gwulo already, this version has a much higher resolution. As commented there, this photo was taken around the 1 November 1869 during the visit of H.R.H. Prince Alfred Duke of Edinburgh to Hong Kong.
On the balcony of Gaupp & Co. it reads: GOD BLESS THE PRINCE ALFRED (difficult to read, but I think it's correct)
First building on the left is Victoria Exchange at 50-52 QRC, occupied by Sayle & Co.
A view in the opposite direction can be seen here. Further comments here.
