Film simulation refers to a digital photography technique that mimics the look and feel of traditional film types. It allows photographers to replicate the color, contrast, and grain characteristics of various film stocks, enhancing the aesthetic quality of their images. Many modern digital cameras, especially those from brands like Fujifilm, offer built-in film simulation modes. These modes provide users with a range of presets that can be applied to their photos, making it easier to achieve a desired vintage or artistic effect without extensive post-processing.
