The first thing every photographer should keep in mind when photographing a religious building is to fully respect the sacred function of the temple and not causing offence while worshippers are praying. A bad behavior held inside a religious building, like a church, a mosque or a buddhist temple, just for shooting photos, is morally unacceptable and it can even put yourself in danger in several countries.
Photographing lakes is a favorite subject for every landscape photographer. Think about one of those North American lakes surrounded by wild forests and snow capped mountains or some European lakes where picturesque and tiny villages reflect into. Probably, the mountain lake reflection is the image most landscape photographers aim to. For a successful photo with a mirror-like reflection, lake water must be perfectly still.
