How 35mm Film Works

Oppenheimer was filmed on 70mm IMAX, 70mm, and 35mm Film, which is basically just Jell-O with some sprinkles. Taking a simple photo with your own film camera also works the same. In this video I explain how film works with 70mm/35mm film in detail of how a simple piece of plastic, coated in gelatin and Silver Halide, allows us to create photos and videos, such as Oppenheimer like I discussed in my last video. I use Jell-O along with 35mm film, images, 35mm film frames from movies such as Space Jam, to help build a photo of how film works. I also fail miserably when making the Jell-O film concoction, but I still think I get the 35mm film across. Other 35mm and film concepts are gone over, including positive and negative film strips, and even the chemicals involved.
