In a traditional camera, x-ray film is typically made up of two colors: blue and green. These colors indicate the sensitivity ranges of the film to different parts of the x-ray spectrum. Traditionally, x-ray films are coated with a special emulsion containing silver halide crystals that respond to radiation. When these films are exposed to x-rays, they capture the image with varying densities determined by the intensity of the x-ray radiation passing through different tissues. The final image is developed through specific chemical processes, allowing for the interpretation of internal structures in medical imaging.
