I have spent one month in Indonesia, but the only one day was such a beautiful purple sunset. When the sky turned to this color, I ran for my tripod and took photos for around 15 minuts until sky turned dark.
SUnsets and sunrises are beautiful and vary according to the part of the world oyu are in and the time of year. PRoblem is that there are SO many of these images, they are hard to seel A lot of free images too
Borobudur is wonderful buddhist stupa on Java island neer by Yogyakarta in Indonesia. The best is in the morning when you are on a hill with view to Borobudur during the sunrise. For sure you need the tripod. The foggy morning comes slowly and is quite dark.
On my last trip to Indonesia I have taken some photos that may seem to be dangerous. First was underwater with a beautiful and kindly posin moray with widely opened mouth. And the second was a crocodile posing in similar way. The second might be dangerous, but the crocodile was locked in the ZOO :-). And the morrey eel is not danger for divers.
