I love the new Lumetri LUT system in Adobe Premiere CC 2015. I used one of the preset black and white film LUTs on some GoPro HERO footage I shot, plus I added some grain and croping and here's the result. It's not perfect, but it was an interesting experiment.
I love Black & White 16mm and 8mm film and the look of this piece you got here reminds me of George Romero's 'Night of the Living Dead' very much. Maybe not so much the soundtrack of course.
Very haunting but with a touch of class to the look. I'd like to see you do a more serious dark story next time.
Remember: Black and White can often be really powerful when cut more slowly too.
But please put your camera on some sticks or a steadycam next time...and make a whole film! Because this looks really good.
