The Ricoh GR III has only basic film emulation modes; they're not as detailed or specific as those found on Fujifilm X-series cameras. Under the Image control section, you can find various filters mimicing the looks of negative film, positive film vivid, bleach bypass, HDR tone, cross processing, Retro, and black and white. There's also the option to create custom filters. These processing filters apply only to JPGs generated in the camera (and JPG previews embedded in RAW files), but not to the underlying data of RAW files.
