- Extreme brightness and blown highlights.
- Very flat image due to the fact that the flash is in-line with axis of lens, very few shadows, and what shadows you see is very hard.
That picture is very, very much an ambient light picture - there would be the tell-tale "zombie" skin tone from a point and shoot at that range, and the people would be lit up like lanterns, washing the relatively dark background into unrecognizability.
It would take a skilled photographer with an off-camera flash to pull off that shot without destroying the background, no way that was done with an ordinary point and shoot.
It could just be a camera with a crappy little flash that isn't showing up very much (it is outdoors, after all).
edit: From a reddit comment:
> Notice the focal length. The camera was set to its maximum zoom, and probably has an underpowered flash. Other than specular reflections off a piece of plastic (purse?) under the woman's arm and from the creature's eyes, there wouldn't be any visible effect from the flash.
