C-41 is an iOS application that helps photographers develop film at home by providing step-by-step 'recipes' for different film stocks and chemicals. It also serves as a reference example demonstrating Core Data, unit testing, ReactiveCocoa, and the Model-View-ViewModel pattern in Objective-C.
Use cases
- develop film at home with timed step-by-step instructions
- look up development recipes for C-41 color film stocks
- time each chemical bath while developing film
- learn MVVM and ReactiveCocoa patterns in an iOS app
- study a well-tested Core Data iOS application
When to choose
- you develop film at home and want guided timing recipes on your iPhone
- you want a real-world Objective-C example of MVVM with ReactiveCocoa and Core Data
When to avoid
- you need an Android or web-based film development timer
- you want a modern Swift/SwiftUI codebase
- you need support for black-and-white or slide film processes beyond the included recipes
