Description

Hi all,

When I import iPhone RAWs I get abnormally dark images, while the accompanying JPEG taken by the software on iPhone is clearly several orders of magnitude brighter.
And it's something it cannot be solved with exposure or brightness modifications in darktable, it brings excessive noise to the image.

As I don't know if it's something that darktable needs to implement specific support for this RAW images, I ask.

Software:
darktable 2.0.7 under Arch Linux
Camera+ 9.0.1 on iOS 10.2 on iPhone 6S Plus

Test photo was taken with torch on. Test photos can be provided.
