RecipeCam is an iPhone camera app that brings the film recipe shooting experience to iPhone. Photographers create, import, and apply custom colour recipes as live filters while shooting — replicating the parameter-driven approach from the Fujifilm community.

Core Thesis

We are not building a community from scratch. We are building a bridge to communities that already exist.

Architecture

Built as 8 SPM local packages with a clean dependency chain:

RecipeModel → ImagePipeline → CameraEngine → RecipeStore → CameraUI → LibraryUI → ImportExport → AppShell

Plus a widget extension for home screen recipe display.

Key Features

• 12-stage CIFilter pipeline with 3 custom Metal CIKernels and 8 grain textures
• Pro camera controls — EV swipe, tap-to-focus, AE/AF lock, ISO/shutter inline sliders, histogram overlay, focus peaking
• Recipe system — create, import (manual + OCR), and apply custom colour recipes as live viewfinder filters
• Before/after comparison — long-press to see the unfiltered image
• Export cards — shareable recipe cards in 3 aspect ratios (9:16, 4:5, 1:1)
• StoreKit 2 paywall — freemium with annual (GBP 9.99/yr) and lifetime (GBP 29.99) options
