摘要
A production process of a light amount adjustment member, by which a light amount adjustment member that can sufficiently satisfy optical properties can be economically produced at low production cost and high yield by a simple operation is provided. In addition, a wide variety of light amount adjustment devices and photographing apparatus equipped with a light amount adjustment member are cheaply provided while achieving satisfactory optical properties. The production process of the light amount adjustment member comprises the step of applying a coloring liquid containing a coloring material to a transparent base material using a liquid jet recording process to form a light amount adjustment region having a particular optical density.
