Moms Demand "demonstration" pic uses trick photography
While at the meeting, I wandered over to the "Moms Demand" so-called demonstration. (It was over half a mile from the meeting, but since the object was publicity I suppose its location was unimportant to its organizers). It looked like a hundred people or so people were there (its organizer had predicted four hundred).
To put in context, 300 attorneys attended NRA's National Firearms Law Seminar.
The Moms event was pitiful. One guy sung some sixties sorta-protest songs, while an old lady danced around with a red banner. Two people held a banner where cars could see it.
They had to use trick photography to try to inflate their numbers for a pic. As the linked page points out, they took the photo on an incline. They had some people stand close to the camera, then others formed up 50-100 yards back, at just the right angle to create the impression that their massed group was that deep, when most of the distance was empty space.
Here's an enlargement of a portion to show how they did it. Notice the rear ranks are far apart from the front ones.
In the full picture at the linked page I counted a total of 102 people, right about my estimate. With the trick photo, it seems like 2-3 times that.
