拍照 taking a photograph

昨天被天我想了给拍照。
Yesterday I wanted to take a picture from the sky. (from the sky?)

It was in the middle of the day. （那是中午。）
>> (I don't know how to say this! Is it like this: 这在中天了。 ？？)
>> (How should I say: It was in the afternoon and I was waiting for the bus. ??)
>> (Is this correct: 我等着的巴士。)

中午的时候，我正在等巴士（公交车）。
