HMS Belfast /Hong Kong 1950-52

Hello, I am new to this forum. I am a current resident in Hong Kong and have recently received some photographs of my Late Grandfather who came here between 1950-52 on the HMS Belfast. It is my intention to take on a personal project exploring a 'then and now' family portrait. I would really value any help or pointers on getting started. I have both books listed here which are wonderful and a selection of other old Hong Kong books. I would be particulary interested in viewing historical images or even purchasing old images but not sure how to go about it. The photograph that I do have can be seen below which I assume references the name of the photographer. 

Note: I would like to add a photograph, but can't seem to find the media attachment option.

For information the chap on the left was my late Grandfather,Charles Warner who was from Manchester, U.K. The two other officers are unknown. 

The uniforms are not those worn by officers, so the three friends must have been ordinary seamen.

Thank you, you are right. He would of been 18 at the time of the picture and his role on the ship was a Stoker.
