Simu — Film Recipes

Screenshot in, C1–C7 out. Simu reads the settings of a Fujifilm recipe out of a screenshot and writes them into the camera's C1–C7 custom slots over USB. No internet. No account. No cloud AI. No subscription. FROM A SCREENSHOT Screenshots of an Instagram post, a Threads reply, a Xiaohongshu card or a web page. Up to twenty import at once, and one recipe can span two screenshots. FROM THE SHARE SHEET Take a screenshot, tap the thumbnail, then tap Share and choose Simu. Images in Photos share the same way. Images can also be dragged onto Simu or imported with a Shortcuts action. READING THE SETTINGS Recipes written in English, Japanese, Traditional Chinese or Simplified Chinese are read on the phone. A value Simu is unsure of is marked Check. A setting the recipe lists but the screenshot does not show clearly is marked Unread. The photo in the screenshot is cropped square and saved with the recipe. Recipes and kits are shown with that picture. FROM A CAMERA ORIGINAL An original JPEG or HEIF from a Fujifilm camera records the settings it was shot with, and Simu reads them from the file. A photo saved from a website or a post no longer carries the settings and is read like a screenshot. Smooth Skin Effect is not recorded in the file. The location and serial number in a photo are not used or kept. INTO C1–C7 Connect the camera over USB and pick one of C1–C7. Settings a recipe does not mention are written as the camera's neutral values. Every slot is backed up before it is overwritten, and writing starts only once the backup is saved. Any write can be put back. KITS AND SHARING A kit is a strip of film: seven frames for C1–C7, each with its recipe's picture. Tap an empty frame to choose by picture. Drag one frame onto another to swap them. A kit is written in one go, and slots it leaves out keep what the camera already has. Any recipe or kit can be shared as a short code, a link or a QR code. Codes include a checksum, so a code cut short by a messaging app is rejected. A code holds the whole recipe, with no server involved, and the format is published. SEARCH Search covers names and settings, so Classic Neg finds every recipe that uses it. Results can be narrowed by film simulation. Recipes also show up in Spotlight. WHAT THE SETTINGS MEAN What Dynamic Range, Clarity, WB Shift and the rest do, plus the range the camera accepts and rules the manual leaves out: • Clarity cannot be written while Image Quality is set to HEIF. • D Range Priority takes over Dynamic Range, Highlight and Shadow while it is on. • DR200 needs ISO 320 or higher; DR400 needs ISO 640 or higher. FREE AND PAID Reading screenshots and photos, organizing kits, sharing, and the settings reference are free. Writing to the camera is a one-time purchase that works on every device with the same Apple ID.
