The cinematograph camera is designed to withstand the most adverse conditions and climatic fluctuations; consequently, only the best selection of materials that can endure warping, shrinking, etc. are used to make it. The camera is a vessel protecting other compartments inside it for the film boxes of the exposed and unexposed film. Again, as the emulsion layer (especially the negative) is very sensitive to light, the camera functions to block out light except when it is required to create images. While certain air conditions are not integrated within this portable scale, the impact of environmental conditions on the film is undeniable. For example, despite the superior craftsmanship of the cinematograph, making motion pictures of acceptable resolution for viewing when in the humid tropics is close to impossible.
