After updating to v3.5, Darkroom will automatically load the depth map for Portrait photos encountered in the library and recreate applied blur from scratch, handing control of its strength and location back to the user. Thanks to a new depth range selector, it's now possible to define exactly where the foreground and the background are.
Meanwhile, in what the developers are calling an industry first, Darkroom 3.5 now features Depth-Aware filters. These come premium Portrait Filter pack to be depth-aware. Each filter will automatically adjust foreground and background settings to optimize the focal point of the image on the face, not on the background. User-created filters with depth settings also now carry over those settings to the filter itself.
Additionally in this release, Darkroom's RAW engine has been rebuilt to take full advantage of the Extended-Range color space of Raw files, which should enable photographers to dramatically improve the amount of detail that's recoverable from shadows and highlights. Similarly, the brightness, contrast, highlights and shadows sliders have been rebuilt to operate in the extended space, offering finer-grain tone control.
Elsewhere, the developers have undertaken app-wide performance refinements in an effort to make photo editing in Darkroom as fast as photo browsing. There's also now a dedicated button at the top of the library view for accessing popular third-party camera app Halide, ready for when the announced Darkroom X Halide integration goes live.
Darkroom is a free download from the App Store and includes in-app purchases for some tools. [Direct Link].
