A process for producing a thin film of unoriented cellulose ester held under uniform tension, the process including the steps of: casting a solution of cellulose ester in an organic solvent over a smooth glass plate and thereafter removing the solvent to form a thin film of a uniform thickness on the glass plate; permitting the thin film to separate from the glass plate by immersing the same into water; and recovering the thin film from the water and setting the wet film on a supporting mount, followed by drying the same.
