Help for the on-device camera and print-effect editor.
Open iOS Settings, choose CMYK Camera, and confirm Camera and Photos access. The app asks for each permission only when you use that feature.
Confirm Photos access and available device storage, then try Export again. All rendering is performed on device, so larger effect stacks may take a moment.
Use the developer contact available from the CMYK Camera App Store listing. Include the app version, iOS version, device model, and the steps that reproduce the issue. Please do not send private photos.
