The old practice is to position the camera on eye level for close-ups (shoulder shots). While for whole body shots, on waist level.

I’m no expert but I’m about to share what have been the practice of more “adventurous” type of photographers.

For people who wants to look slim on their photos, the camera man should position himself from above making the subject look up to him. You could place it on high tv stands or use a ladder. This has been the favorite shots of teenagers using their mobile phones.

For celebrities (e.g. politicians), you would always want to position the camera a little below the subject’s eyeline. Some even dare to position the camera below the subject’s waistline. This is to make the one viewing the photo “look up” to the one on the photo.

Moreover, you can experiment different places of your camera to achieve creative shots. Happy shooting!
