Color Grade Your video Clips in Darkroom App for i Phone and i Pad. However, you will find rgb curves, a host of sliders and can even use the histogram when making adjustments to video clips. You have exposure, color temp, and tint, which alone can get you most of the way to correcting a video clip, plus more tools to create almost any creative look you can think of.
What most interesting to me is that although it clearly a toolset that comes from the photo editing world, much of the underlying math and operations are the same as what is required for video, only the way it is visualized and how you interact with it is different. Sure, there may be a few tools that are either missing, or present but not quite as you would prefer for video, but the Darkroom toolset does not take much….
