How to say "smile" and "look at the camera" in spoken English?

In fact, you can say anything with a smile, depending on what makes you laugh. Only more people say "cheese". You can also say "jerrybeans" (a colorful candy). A group of teachers took pictures and everyone shouted "holiday!" Some people don't like "cheese", so they say "money" and "raise!" (salary increase)

Look at the camera: This way, please! /Look here! /Look at the camera/Look at my hand (usually the photographer raises his hand)
