The curves tool is the most flexible and powerful color correction tool. You may know it from the DaVinci Resolve Color page, from Photoshop or from other applications.
You can easily perform the lift, gamma, gain, and contrast operations with curves. This gives you the flexibility to adjust individual channels while keeping an eye on the overall adjustment.
The curves tool is ideal for compositing. Match black and white points manually or do gradual adjustments of contrast and saturation to create a believable composite.
