Does anyone know what type of glass or filter Rodrigo Prieto used for his Lana del Rey music video "Blue Jeans"? I'm really interested in creating a similar look for a dream sequence I have to shoot next week. I have already tested with old 1800's window glasses and it creates a really cool look, but I'd like to know what material created the particular refraction we see in this MV. Thanks for your help in advance! LINK: https://vimeo.com/38985704 Diego Gilly Cinematographer Los Angeles
