This is the most southerly of the islands around HK and takes around 40 mins to get there on a ferry. Only one ferry there and back a day four days a week. We went on a Thursday, and if you miss the ferry back you are sleeping under the stars there until Saturday when the next one comes I think there's only 100 people living there now and are mostly fisherpeople. It's a nice peaceful place and pretty popular for camping.
I took the F3HP with Portra 400 @ 320 & 24/2.8 N.C. + 35/2 O + 50/1.4 S.C + 85/1.8 H.C. I metered for the green which was usually around 1/500 and used a 2-stop GND for the sky in some cases. I think there was around 3 stops difference between the sky and the mountains but this is no big deal for negative film.
