I've done years of research on this and I've found shooting at night under certain conditions removes most shadows depending on moon phase
This technique while effective may have unforeseen consequences like not being able to see the subject you actually want to film and crashing. The finished product could have less detail than filming during the day and you may need to add lots of text graphics and narration to help the viewer imagine what it is they're not seeing. An unintended benefit using this method is you won't have to worry about things like white balance, exposure, or frankly even remembering to hit the record button. Until you've mastered this technique I suggest you don't use it for things that are important because let's face it not everyone will appreciate this "thinking out of the box" style of video. For those nay sayers I say who's the Film Maker? Don't let short sighted people hold your creativity back **** it!
