What equipment should I bring when I travel to Tibet to take photos?

Your equipment is a standard portrait equipment. If it is a portrait. It is recommended to bring a hot shoe flash, preferably a wireless receiver. In this way, if you have an assistant, you can take great photos of people. The lights in that place can't shoot people on a sunny day without lights. . .

I don't know much about taking pictures of scenery. Dare not talk nonsense.
