I was for a short time, a WAM video producer, but now am just a collector.
I tend to like videos for messy, and photos for wet, except dunk tanks where I like both.
I really like what I call photogenic models. Show off to the camera in photos, and talk to the audience in videos. Almost no producers do this anymore, so I will never ask for a custom unless it starts going back to what it was originally.
I do have some cool ideas for producers but I haven't made any suggestions yet.
