this Kodak promo I had an image of lights flashing in front of a camera to reveal a logo. the technique used here, by simply aiming a flashlight at my phone camera created an abstract representation of camera film being exposed. I felt this paired particularly well with Kodaks branding and successfully implies a sense of tactile in camera effects.
Using just one unedited shot made by adjusting the exposure n my phone I was able to create an abstract represntation of camera film being exposed.
