This trip is an organized trip by a tour agency. Places to be visited includes the night markets, Pu Li (scenic location), Kaoh Siung, some theme park, memorials, and since its a band trip...music exchange with 2 local schools.
hmmm.... would you have time on your own of the urban sides? walking around is the best way to get good stuff, and this is where organized trip will affect that.
yah, band trip, sounds like you will get lots of chances for portraits.
1. What to bring? I currently have a Nikon D80, 18-200VR, 50f1.8, SB600 which i intended to bring there. Should i bring the 50f1.8? How about tripod...advisable? I'm bringing a Lowepro CompuDay.
check out my thread in the signature. considerations on travel, outdoor and streets are about the same. country does affect little, your preference decides out.
in my opinion, 50mm f/1.8 is good for portraits and fast lens. it doubles as a near macro too.
tripod, bring a light one if you want.
bag wise depends on your preference.
2. When you alight the tour bus for tours, do you bring everything out with you? If not based on my setup, which should i bring out. How about flash?
except for bag and tripod, bring everything out. you are still leaving the bag and tripod behind as a risk, but they may be worth the risk as they can be optional and bag can be more easily replaced. flash, up to you, as it is not unlikely to be useful for midday shoot unless you are familiar with fill flash.
3. What is the weather there like? Any tips on camera care (other than the obvious) specific to taiwan? I intend to wear a jacket and hide my camera inside when not shooting...good idea?
weather is volatile. and if you need to go up mountains, it can get colder. if you can hide camera inside jacket, by all means, if you can. mine is too big and looks awkward.
