1. He took a picture of the house.
2. He took four pictures of the house.
3. He took some pictures of the house.
4. He took pictures of the house.
Are they all grammatical?
Does #1 mean that he took just one picture?
Does #4 mean that he took more than two pictures? If we took just one picture, can't we use 'took a picture of'?
