How does *color* film photography work??

Listen Later

In this continuation of our two-part series, Melissa and Jam dive into the intriguing chemistry behind color film and Polaroid photography. The episode picks up from the previous discussion on black and white film, focusing on color theory and how it applies to both traditional and instant photography. Listeners will learn about the science of additive and subtractive colors, how multiple layers of dye-sensitized silver halide work together to capture images, and the unique processes involved in developing these images. For those fascinated by the intersection of chemistry and photography, this episode is a must-listen.
