I am looking for a solution (preferably free of cost) to capture photos in RAW mode on my iPhone 6. The solution/tool should be able to capture RAW mode image before camera converts to JPEG/PNG.
I am also willing to Jailbreak the device if required.
Best Answer
The built-in camera app in iOS doesn't support capturing RAW photos. You'll have to rely on a 3rd party app.
Since you are not looking for a paid app, you can download VSCO a free app that supports capturing photos in RAW mode.
OTOH, on the paid front, Halide Camera is a highly regarded app by photography enthusiasts and power users alike.
Note: No affiliation whatsoever. The answer is based on personal experience and ratings on the App Store.
