Yes, I see your point. To, me there are no right or wrong answers. This kind of topic can be argued to death without much conclusion. Like asking which brand of camera is best. I think at the very best, we can only say it's a difference of opinions.
Just as you mentioned some like singapore after staying here for long, I've also come across my fair share of expatriate colleagues who say they don't like singapore because either of the weather and most commonly, it's too "wholesome" and does not have any "rustic charm". Everything looks too perfect and regulated. All of them have since left singapore to either go back to their countries or work elsewhere. In fact many of them came here cos it's a good base to see the other more interesting parts of SE asia like thailand, cambodia, etc.
I'm not saying singapore has no good places to photograph. But after a while, yeah, TO ME (my opinion), it's boring. Not cos you can't find different angles to shoot from, but it's the same old subject. The chances of you getting better lighting, fantastic skies is a lot higher in temperate countries than Singapore. Of cos there are days where the place looks terrible but not for long. But cos the places are so big, you feel uninhabited. Like I said, if you feel singapore is a joy to shoot, if there are 10 different angles you can take on the MBS or buildings for eg, then there are 1000 or more different angles and subjects you can shoot overseas!
The disadvantage with singapore is its equatorial location, and its tiny size. There is nothing we can change about that.
Ok, just how i feel. One man's meat is another man's poison...
