Hong Kong street photography?

Here are some places. Hong Kong is sometimes tricky to shoot because things are in most cases too close up for the size they have. It's not easy shooting 40-floor high buildings when you are standing in front of them. I find my 15mm fish-eye very helpful at times.

• Mong Kok: VERY dense place, lots of small shops
• Causeway bay, specially around Sogo and Times Square for another busy area, more modern.
• Western Hollywood road, Man Mo Temple and the pedestrian street between Hollywood and Lok Lu Road. The smaller streets between Hollywood road and Wellington Street around Gage street have still some small manufacturing companies in open garages. You can see printing presses and others right on the street if you go during business hours. At night, many small restaurants opened there recently.
• Wan Chai at night for the red light district and the dark side alleys between the buildings (no worries, it's save, but bring a f/1.4 lens. Between Wan Chai And Causway bay there are several interesting small restaurants and shops, where a lot of things such as cooking happens on the street.
• Cheung Chau or also- Tai O on Lamma island for some more rural, traditional housing
• The fish traders on the sai kung pier (a bit further out) where fishermen in small boats sell fresh fish to people standing 5 meters above on the pier
• Central where (somewhat) old and new things contrast, specially old buildings and sky scrapers. Here, getting the right angle and position can be tricky though
• Dense housing in Taikoo Shing
• The rooftop parking lot of the Ocean Terminal for great, obligatory unobstructed harbor shots, favorite for photographers, reachable through the Marco polo hotel
• The spaces under bridges at the Wan Chai MTR (Exit A5) and Causeway bay flyover near Russel Street / Canal Rd. You always have older HKG residents sitting there, some performing fortune telling and cursing for people.
• any of the wet street markets

Most important in Hong Kong is leaving the main road, almost all of the side streets offer interesting views of old Hong Kong lifestyle.

One more thing about dealing with Hong Kong people: Do not expect politeness, but neither aggression from people, be it as a restaurant customer or as a photographer. It rather follows the "tough love" principle. People are doing their job, you do yours. Smile at them in a possibly warm way, bow, excuse yourself, do something to brighten their day, and you will have a great day. For examples merchants in markets LOVE the attention of a photographer on how they arranged their food. Buying something does not hurt (prices for fresh food are amazingly low anyhow compared to Europe for example).
