Hi everyone,
I’m working on a custom camera implementation in iOS using native code. My goal is to capture unprocessed, realistic images directly from the camera — without any filters or post-image processing applied by the system.
I’ve implemented RAW image capture using the native camera APIs (AVFoundation) and successfully received .dng files. However, even the RAW outputs don’t look like the real environment — the colors, tone, and exposure still seem processed or corrected in some way.
I’ve tried various configurations such as photoSettings.rawPhotoPixelFormatType, experimenting with AVCaptureDevice and AVCapturePhotoOutput settings, and reviewing ProRAW and standard RAW behavior, but I’m still not getting truly unprocessed results that reflect the actual sensor data.
Has anyone experienced similar results when capturing RAW images on iOS, or found a way to bypass Apple’s image signal processing (ISP) pipeline for more realistic captures? Any insights or references from Apple’s camera framework behavior would be greatly appreciated.
Thank you!
